Rocks

Granite

>>8223693
Great help, thanks.

>>8223695
You're welcome.

I am unironically a geologist too, so you can rest assured that those rocks are indeed granite.

>>8223698
Can I get some actual help please.

>>8223700
Sure

Quite sure that those are rocks.

Better light and closeups please.

The red one is steel.

Those rocks look like they were naturally made

Very sure that those rocks are made artificially.

Ignore the Finish, they've never contributed to anything in society anyway.

Why would you even start if you don't finish?

They're minerals! Jesus Marie

BAH GAWD

IT'S THE ROCK'S ILLEGITIMATE CHILDREN, THE PEBBLES

I'm a geology student. Polished rocks are really hard to identify.

Rock classification is based on rock composition (which I can't do from here) Size (which I can only guess at), Shape, and Sorting.

The only ones I would feel confident in is the Marble in the center, the red Chalcedony, and the sandstone on the right side. Probably a Lithic Arenite. Depends on if it's a lot of rock fragments or feldspar. If feldspar than it's Arkosic Arenite. I can only guess by color.

Take them to your local college earth science department.

The rest I wouldn't even want to guess at.

Dark slab second from right is basalt
bottom three shinies are metamorphic but can't tell from here

Red shit is jasper

Center is quartz
Top left probably basalt

Top mid looks sedimentary
Far right some kind of concretion.

Far bottom right who knows.

all of those rocks are diffrent because of artificial selection

Why do you have these rocks lol

>>8223691
upper left and other thing that looks the same is gabbro i guess
and under the upper left one is andesite

don't take his response for granite

>>8223691
center white looks like calcite
red is definitely jasper
large edged rock is flint, maybe basalt

I'm no geologist but the little brown one to the middle left kinda looks like weathered chert, though I'm not sure if that's a dumb assumption.

This is a really good thread for this board

>>8223691
can you upload a gsmc? you alrady have cmos

A what? Get outta here, nerd.

I agree with this comment.

Use a scale bar when ever you take photographs, it really helps preferably millimeters since most of the world works in those units.

It would be useful it you could do close ups, so that we can see the individual grains "crystals".

I'm not sure if it is true for all lenses, but prime lenses behave as macro lenses at the minimum focusing distance.

Get yourself a some glass, a streak plate, steele nail, and some HCl.

These things are what you need if you want to work out what minerals are in your rock if the grains are big enough.

get a magnifying glass and take a closer look and you should have all the tools you need to start geologising.

This should have happened sooner and the thread should have ended there.
