It doesn't look like typical meteorite pics so I'm asking for advice. One guy in the last thread (on /b/, I wrongly assumed some experts still /b/rowsed) posted a meteorite pic that looked strikingly similar to the shape as well as surface texture.
I don't have any magnets but some stuff clung on to my tweezers when I tried to sift through to show you guys big piece of what's fallen off.
This is the rock, the next pic will be some of the stuff that's fallen off onto what it was set on. I've taken this pic on standard printer paper for a size reference, it's 15lbs.
I even have a blurry video showing the stuff sticking to my tweezers if anyone can tell me how to make a webm.
Please refrain from commenting on here/hear typo in the OP. I apologize and am not realizing how out of it I currently feel.
Here's the "stuff", I'm currently showing how it surprisingly stuck to my tweezers, and if you note between this pic and the next the different in how much dark dust stuff is sticking to these little colored rocks I'm sure you can see that whatever this stuff is it's clearly magnetic.
Here's a pic I took of those few pieces earlier before I dumped more stuff that fell off onto the pile and realized all the little shavings were sticking to the colored rock pieces.
This was the wrong pic, pic related.
I'll post a few more pics, but if there's no interest or anyone that can help I'll just let this die.
The next 5 pictures are of the top, the 5 after that are of the bottom, then the next 4 are close ups.
This is the bottom, the top actually has more shaving type stuff you can brush off with your finger but the bottom is black. Can anyone tell me why that would be?
Ok, no one is interested, I'm going for a smoke.
4chan "Detected possible malicious code in file image" so I had to skip one.
In this pic you can clearly see one of the reflective pieces of stuff that's all over the rock but the phone camera can't pick up most of them because the reflection is too small.
I don't know man, some legit meteorites can be worth 1000 bucks a gram. I wouldn't trust a college professor with two ounces to "test". I've heard a lot of stuff about people getting rare minerals tested and being told it's worthless only for the guy to take and sell it for a lot of money.
This is the top at a different angle, the bottom will be the next pic so you can really see the color difference.
Not that you have to sell it OP anyways, but having some characterization made on it would be helpful for identification.
Would be useful to do some EDAX (though I dunno about Tc detection).
Here are some close ups. I'd really like to get the opinion of a geologist or at least a meteorite hobbyist.
Only a special kind of Meteorite is worth "1000/bucks a gram", pic related.
Your rock could be a chondrite, which doesn't worth very high price.
Just go ask an expert and keep the rock with you.
I wouldn't sell it, but I wasn't the one that found it I just happen to be the one looking stuff up for her.
Here's a pic of one of the larger reflective pieces and the next pic will be slightly angled without the reflection for comparison.
Lunar Meteorites are worth $1000/gram. I was perplexed because the only pics I could see of meteorites were smooth, had a crust, all this other stuff that looked nothing like what I had. Then one kind anon posted this pic of a Lunar Meteorite in the thread I made on /b/. I checked out the website he linked it to and some of the pics look identical to what I have, right down to the same colored rocks inside when you cut it open that fell off the outside of mine in the first few pics.
Funny story man, when I hold it my hands are gradually chilled to the bones. I don't really have a way to describe it. The rock itself isn't cold to the touch, it's a little cooler than room temperature but when I hold it for more than a few seconds the inside of my hands start getting really, really chilled. Creepy.
Here's the inside of a lunar meteorite so you can see the comparison of the colored rocks to what I posted just after the OP.
How does your grandma know the rock wasn't there? I mean if she leaves shit like that laying around for a month, how can be sure the rock didn't come from somewhere else? Maybe someone moved it doing some yard work and she didn't notice.
Here's why I don't think it's a meteorite. If it hit her house, it would have went through the roof/wall. It wouldn't have just bounced off. If it hit the concrete patio, it would have cracked it and/or cracked the rock itself.
If you really want to stick with the story that it hit her house, I would ask if anyone is doing some blasting in the area. Does she live in the mountains?
I know a legit meteorite dealer. I've helped him handle some specimens. The 1000/gram stuff isn't common. I've seen small pieces of Mars meteorite go for less than that. I've seen a $4000 slice that used to be in a local museum and what you have isn't that either. You can trust someone to look at it. They're not going to beat you over the head and take it, especially if it's a professor.
It didn't hit her house, she thought something hit her house when in fact it just hit her porch. I had the same thoughts as you when I was told about it, it sounded ridiculous, I actually thought it had busted up the concrete, and if a meteorite did in fact hit, I was looking at busted concrete and the meteorite was something small sitting in the rubble.
However after looking at some of the other moon rocks and seeing that the little pieces coming off of it are magnetized I'm leaning towards thinking it might be legit.
Here are some other lunar meteorite pics that I've been using to compare the two.
Last one for comparison.
Like I said all I know is what I was told, after being told the concrete around the rock had turned white like it'd been heated, the first thing that came to mind was some kids in a pickup driving around in the back with a large rock, holding a torch and heating it up and then going 100mph and throwing it out and it ended up on her porch.
That was more plausible to me than it being a meteorite, but the more I think about it the more ridiculous that sounds.
A close up of the black part on the bottom.
Here's one more comparison for people saying it would have a huge impact and leave a crater. This is nearly the same weight as the one I have and in sand/pebbles this is the size of the crater it left. It's not what you see on TV. I would say if that hit concrete it might legitimately not crack it. (The concrete patio is 6" or 12" thick)
They want me to pay. But as you can see in this pic the little shavings are sticking to these colored pebbles or whatever.
No. If something is radioactive, the EM waves will cause interference with electronic devices. Putting a camera close to a radioactive source will cause interference with the camera, and this shows up as snow on the viewscreen. You should see like little bursts of color on the camera screen. It should be fairly noticeable if you bring the camera close to a radioactive object in the dark, because the entire camera screen will be dark except for random pixels changing color for half a second. Some shitty cameras will do this regardless though, so try it somewhere else beforehand
A phone might work as well, but you'd probably have to use a corded phone and have the cord go right over the object. Otherwise you can't really tell if you're getting interference from radiation or just because your cell signal is poor.
>rock falls from outerspace onto your grandma's driveway or whatever
>concrete turns 'white'
>no mention whatsoever of physical damage
>rock somehow doesn't bounce/shatter into dust considering the concrete is relatively unphased
this story isn't even cool, faggot.
You watch too much tv bro, meteorites won't even make a small crater unless they're something like 100lbs or more. I read a lot because it didn't make sense to me either at first, but apparently something this size will just land on the ground with a thud, or in this case the concrete.
Here is a super shitty web.m of the small pieces in the 2nd and 3rd pics in this thread magnetically attaching themselves to my metal tweezers and then subsequently becoming demagnetized. If one of you /sci/guys can tell me why they stop clinging on to my tweezers after a minute that would be great.
I did the camera in darkness test, no radiation.
Well, I... I haven't felt like having sex for the past day or so... and I did wake up feeling nauseous in a cold sweat yesterday.... oh god... what's happening to me?
Also I've been growling at anything I don't like, and just randomly... I've had to stop myself from impulses to bite things, random objects, people's throats. Guys, I think I might be turning into a werewolf. Did I inhale too much moon dust? Or some pathogen from the moon? Have we discovered the origins of werewolves? What am I going to do guys?
The color's a little off, and it's not the same shape. If it were then this wouldn't be a meteorite since vanadinite is caused by oxydation. We'll see when we cut it open either tonight or tomorrow.
I agree that it appears to lack fusion crust, but after more research I've read that on rare occasion a meteorite will only have fusion crust on one side, or not at all.
Take a look at these examples.
On top of that I discovered that the little colored rocks inside had magnetic properties as seen here.
you're a fucking idiot.
It's not hard walking into a professors office and asking him what he thinks about it. Regardless of whether he says its worthless or not, you could still keep it.
If a meteor is small enough to be slowed down by the atmosphere it will still hit the ground with terminal velocity.
A rock like that going at terminal velocity would damage the house.
It didn't hit the house, it hit a concrete patio. Not the type of concrete cinderblocks are made out of, the darker, denser concrete, whatever that is.
Kitchen magnets don't work, but if you look here >>6565825 you can see that the colored pebbles inside have magnetic properties, and the shavings that have fallen off of it are sticking to them. However it looks much more like a stony meteorite than a metal one. I still haven't gotten around to cutting a piece off to send somewhere.
All the metal meteorite pictures I've looked at look WAY different than this, mainly because of the obvious fusion crust. However, Lunar and Martian Stony Meteorites look much more similar to this one and some can have little to no fusion crust. Don't ask me why, I'm not a scientist.
This whole thread pic related
>As I said in the thread on /b/ last night; it appears to lack a fusion crust
Lacking a fusion crust doesn't mean it is not a meteorite, sure most have them but some don;t and meteorites value is primarily determined by it's uniqueness so that is at least hopeful for op
>Grandma here's loud noise
I already knew what that rock was the second you posted this thread but I was banned so I had to wait till now to reply.
Those are chondrules. And the redder pieces of rock are olivine and pyroxene.
And of course
Iron metal which explains the magnetization properties.
What you have here I am sure OP is a very common meteorite which falls roughly udner the H chrondrites, however,this is a rather rare type of H chrondite, so rare it doesn't really have a classification to itself.
However that being said I don;t think it is extremely valuable. but it should be more valuable than normal H Chronicles. When you cut it open you will see a beautiful cross section of the olivine and pyroxene which should appear as red and yellow circles within the rock and some glitter of iron.
Thank you for your very informative post. It sounds like you're familiar with this stuff, is it a hobby or something to do with your job?
Yes. Though after reading the previous post I feel invigorated to get started. My sleep schedule is pretty messed up and I was thinking about hitting the hay but now I'm considering grabbing the saw right now.
How would I even do that?
At first I half scoffed, half laughed at your post. Now I'm thinking something along the lines of "How often does someone get a chance to put his member on something from space?"
No pics for you bro.
>How would I even do that?
Easy, m8. Think about what density is. (hint: kg/m^3).
All you've gotta do is fill a big container with water up to the very top and drop the meteorite in. Then you measure the volume of water that was pushed out of the container. This is the volume of the meteorite.
Then you just find the mass of the meteorite.
Then you divide the mass by the volume. Bingo. Density.
Also, how would you suggest cutting it? Just completely in half? Because I'm kind of strange, and feel it's a shame to cut it at all. I know it has to be done but I feel like it's a loss to disturb the preservation of it's natural form.
There is a small "knob" on the bottom that I could hack off, I was looking for a spot that wouldn't disturb any of the maximum dimensions of the meteorite. So I looked for something that wasn't something that any measurement would be taken to determine the meteorites maximum size. That includes extreme point of the X, Y, *and* Z axis. There is a small knob in a larger bowl type area on it that measures about 2.5x2.5 inches but I'm considering that it's possible this does have some kind of crust, and that spot may have been on the back end where the entire knob is made of crust. So it could be completely pointless to cut that off and I'll just have to cut again somewhere else.
Pic related, to be precise.
Neat, except I'm not dropping it in water. There's a lot of dust and stuff on it that's pretty fucking cool, so I don't want to wash it off.
Also, picking it up and flipping it over cause a piece that sounded large to fall and hit the cardboard, and I think I lost it.
Actually man, no moon rock has ever been found on North or South America. It would be the first, also it would be the third largest ever found. But our friend who sounds like he knows what he's talking about is saying it's one of the most common ones.
You've convinced me. Now... what do I use? I have a lot of tools at my disposal. Circular saw, sawzaw (is that even how you spell that?), dremel (I don't know how to spell tools, I just use them) tool with a very small circular blade... chainsaw. Chainsaw? God that would be badass. Maybe on my next one.
Lots of sociology subjects in past degrees and I'm currently working towards becoming a teacher. American teacher standards aren't that great and the curriculum is pretty silly right now. I miss the days of primary students being hands on with stuff like displacement. Remember to be a good dad and do this sort of stuff in the yard with them!
I have to wait for my dad (not underageb&, economy stuff) and he's bitching about not wanting to cut it right in half. Some website he found said they only want you to send them 4 grams or so, and that's pretty small.
I can't find my 2"x2"x3' industrial magnet, and kitchen magnets don't stick, no. However, if you read the thread you would see that material that fell off is magnetic, as demonstrated in the .webm that I posted showing them attaching themselves to my tweezers.
About three and a half hours when my dad gets back from his dr. appt. He said he's got a handsaw with a very thin blade, still only going to cut off a very small piece though. It's probably going to be like 1/2 or 1/4 inch viewing hole. I feel like I'm going to be disappointed. I really do want to cut it in half and view the beauty of what is inside, if I could I would cut it flat ways from one side to the other so I would be left with a top and bottom half and could have the most viewing surface as possible.
Ok, here's something I'd like to know. Why doesn't it have a fusion crust? I mean, they're supposed to heat up right? Unless an alien came down and dropped it 100 ft or so over my grandmother's house... hmm...
There are chondrules literally falling off the outside, that seems really strange to me. Especially since they're almost like spongy rocks and felt like bread crumbs in my fingers the first time I picked one up.
The meteorite was sitting on a paper plate, I literally thought someone was stupid enough to sit it on a used paper plate and I was picking up stale bread crumbs. That seems like it would burn off or something, so why didn't it?
>Lacking a fusion crust doesn't mean it is not a meteorite
if it supposedly just fell and it doesn't have a fusion crust then that's a pretty strong indicator that it's not a meteorite.
That just goes to show how misinformed people are on the internet, it was practically a witnessed fall son.
>Grandma chilling in her house
>Hear wall shaking BOOM
>Grandma goes to look
>Sees rock that wasn't there a minute ago
Regardless of whether or not it's likely, what you're looking at is a meteorite without a typical fusion crust. Take a good look, because now you know what that looks like and can identify other meteorites without fusion crust and feel superior to your fellow man, like I know you like to do.
I just woke up, and my dad is still awake about to go to bed. I should be cutting it open somewhere around noon or afternoon.
Not a lot adds up to it being a meteorite. A lot of things are off about this but who knows it's not out of the question. .
the only way your actually going to find out if it's a meteorite is if you bring to someone that knows their shit, prob at a local university. Don't give it to them if you dont feel comfortable doing that but your going to need a professional opinion. maybe let them cut off a small sample. don't cut and mangle it all to shit yourself cus maybe you have some rare type and it'd be worth a lot to a collector. Probably not but it's worth taking into consideration. They aren't going to fuckin bash you over the head and run off with it so you don't need to worry about them saying its worthless and taking off with it. If they bring it up, make it clear your not going to sell it to them without second opinions and whatnot so they have no motivation to lie about it. I think it's definitely worth checking out.
Also, look into sightings in your area around the time you Grandma heard it. Something that size may have been visible coming down.
One of the anon's that sounded pretty informed >>6568467 recognized the stuff in this pic >>6564425 as chondrules. People are saying the red stuff looks like this and that, but everything they're suggesting it may be are very hard crystals with specific and defined shapes. While this stuff is brittle (the smaller pieces anyway) and not very well defined.
I didn't find anything around Jan/Feb this year but I did find this website.
I ctrl-F my city and am seeing that people have seen strange crafts flying around with jets following them and stuff recently. Feels pretty weird man.
Follow this link then click on your state and ctrl-F your city.
Really. I was out of it and I apologized in the second post bro.
Also I found something pretty neat, a gif of a meteorite flying past a skydiver.
I think I heard of this on /sci/
It's really cool because it's one of the first times that a meteor has been photographed in the dark phase of it's travel (when it's not burning up).
There's a video of it somewhere, and they recreated the event on 1000 ways to die. He was standing on a deck, leaning on wooden railing in front of a pool. The meteorite came through the middle of his chest and landed in the pool. He was not alright.
