Geologic Structures: Quartz veins in slate

[@stevenbaumann8692]

I took accurate measurements and samples in December 201&. The quartz is not hydrothermal. After detailed study, I am convinced it is a quartzolite. It was a magma of almost 100% quartz. There were enough other minerals to culminate out some Muscovite, that settled at the bottom of this small magma chamber!

This is why I read the comments under your videos too! I'd never heard of quartzolite!

Yes I did learn something. I thought all veins were hydrothermal. So you're saying it's not actually a vein at all, just magma that consisted of quartz and cooled? But then it also is highly mineralized like a hydrothermal vein. I'm new to this so appreciate all the info.

[@stevenbaumann8692]

@@goldiswhereyoufindit that's fine. I use to too. There is a bit of a theoretical overlap too.

Hey from Australia. Watching for the first time on the 6 year anniversary of filming. I saw some of my own slate rocks with quartz crystal near my home today, went to research and found your video!

[@stevenbaumann8692]

Thanks! I hoped it helped. And welcome to the channel.

See, and I even know what banded iron formation are because of a previous video; I'm learnding

My friend just brought me a rock from Alaska. Everyone on a rock identification group is telling me it’s quartz vein in basalt

[@stevenbaumann8692]

That is possible with later hydrothermal activity. So are calcite ones.

[@ferneycastano2257]

I have always had a question that I have not been able to solve, what are all the possible vein ocurrences?

[@stevenbaumann8692]

That's a loaded question. I would say mostly magmatic, hydrothermal, and groundwater.

Do you have other videos?

[@stevenbaumann8692]

Heather Kipp yes. Many more. Some are in playlists.
