Hello new followers! I’m Lizzy. My expertise is ore geology and mineral exploration, but I’m interested in all aspects of earth science. I’ve been a field mapper, lab scientist, adjunct faculty, and currently a SAHM because the job market is always up and down 😄
You probably wouldn’t see nice crystal faces either way, but I don’t see any cleavage planes which is one reason for my guess. It’s hard to say though since they are so tiny

I’ve been listening to this song since it came out and today was the first time I’ve watched the official video and I can’t believe I never knew about the gold mining metaphor in it

Oil geologists, if there are any on here: was the oil at Spindletop Jurassic in age (I know the salt dome it came out of was) or did it seep up from the Paleozoic? I haven't been able to find a clear answer on this, and I'd really like to know!

This @nytopinion.nytimes.com op-ed on rare earths repeats a misleading story: that China dominates these industries mainly because of lax labor and environmental standards. It sounds intuitive, but it’s analytically wrong in ways that matter for policy. 1/

How does sand mining reshape rivers?
@drchrishackney.bsky.social explores how #sandmining is transforming riverbeds in the #MekongRiver, #Cambodia. His work shows that bedforms become larger, steeper, and rougher than natural ones, altering flow and #sediment dynamics!

No this is either andradite or grossular garnet but I’m not sure which

That one is pretty but certainly very different than the other ones.
It looks like the green may be epidote. It is a low grade metamorphic mineral and you can see it as little veins like that.

Nice marble and looks like maybe the small minerals are garnets

White could be wollastonite. Needles could be either wollastonite or an amphibole like tremolite or something. I also think I see some small red garnets.

I would say this could be igneous or it could be metaigneous (metamorphosed igneous rock). If it is metamorphic I would still call it a gneiss even if you don’t see the classic gneiss layering. This is one reason why where it comes from matters. Sometimes it’s not that easy to tell with hand sample

Not all metamorphic rocks are foliated, especially if they form by metasomatism (magma cooks the rocks that it intrudes into). A skarn is an example of that. Many marbles and quartzites are also not foliated. Some igneous rocks that have been metamorphosed also can not look very foliated.

Today’s my birthday, and I wanted to share two of the books I received. Excited to read both!

Obviously I could be wrong. Do you know geologists in the Capital District? They might recognize it right away.

They don’t transport aggregate that far, especially when there is lots around. This likely came from a New York quarry, and I think this rock is actually metamorphic. Lots of quarries in the Adirondacks and this very much looks like the rocks from there

This is one that’s not easy to ID with a photo 😅 and I might have made different guesses if you didn’t mention where you found it.

But my other guess is that this is actually wollastonite and a pyroxene from a skarn. I actually may lean more toward this one actually.

So you saying this is from Milton, makes me think this is from a quarry in the Adirondacks. Rocks from there are granulite facies metamorphic rocks and have a lot of feldspar and orthopyroxene. So I suspect that’s what this is.

I never learned to study. I just have a good memory, pattern recognition, and math skills. Now, I’m failing at teaching my oldest kid study skills because I’ve got no idea what they are.

They also make fleece lined tights. I’ve been thinking about buying some of those for myself.
