Is there a specific name for this variety of quartz?

Geofag here

Quartz and maybe cordierite?

>>9018235
If it's metamorphic it's migmatite, but the texture looks strangely glassy in the photo

Blueschist

Blueschist facies again.
Yeah it's quartz and garnet I think. Green is probably epidote.

P.S. I'm guessing you think that blue mineral is azurite.

One way you can test easily is to try scratching it with a key. If it azurite it will scratch easily, if not it's probably cordierite.

Thank you very much based geofag!

Definitely not azurite.
