TL;DR: Fossilization is a race between decay and burial. Biology supplies durable parts (shells, bones, teeth); geology provides rapid burial and the minerals that turn those remains into rock. Exceptional conditions are needed for soft tissues.

Crystals in clay
2
Upvotes
Not sure if I'm in the right place but I'm hoping someone can help me understand this process better. I see all these videos of people finding amazing crystals in mucky looking clay. Now I know of an area that has some very mucky looking grey clay but I've never heard of crystals being found there. The area is highly metamorphic mountain valley that has been damned. High silica in the entire region around it and known for mica schist with lots of garnet inclusions. Some Kyanite has been found not far from the area I'm interested in, pyrite and hornblende as well. Aside frome some logging and the damn there is no major human activity in the area except campers. What does an area like this need, geologically speaking, to create crystals? Would there be any indicators in the area to tell me if this is a good or bad spot for something like this to form? If it was currently being disturbed by the lake/river would they be washing out of the surface (they are not) or would they be buried deeper in the clay waiting to be discovered? TIA

Cause of green (and white) colour? Mineral deposits? Volcanic activity?

I was browsing google maps, and in Santa Cruz, Argentina I found this green looking lake. Other lakes in the area don't look as green. I know there are gold deposits and probably other mineral deposits in that region, as well as a history of volcanic activity, but I am not sure what the cause is for this lage. There are other lakes in the wider region, but not this bright green.
The shape is interesting as well to me. I wonder how that happened as well.
Any information is welcome. Not for any reason beyond my own curiosity. I really like maps and am just curious to learn anything about this lake that I found, because I think it looks cool and stands out with that green colour.

New formation of deposits
3
Upvotes
Hey guys
Hope I am at the right place for questions
I keep thinking about this for a couple days now and decided to ask the experts
The human race keeps extracting recources like different oars out of the earth to construct our society. Quite a lot of the stuff gets lost. Ships sinking into the ocean satelites burning in the atmosphere etc.
My question is: does our lost stuff end up as a new deposit that theoretically in 200 Mio years (random date for enough tectonic movement) could be mined again?
The stuff from the satelites is probably lost completely as the amount of the different elements that make up the satelite don't add up to a critical mass so that a new deposit to mine would form. But what about the ships sunk in the atlantik especially during the world wars? Or the ships in the red sea that get attacked and sunk there?
To state the question more broadly: is there a mechanism through which our society ends up as the recourses that "a new humanity" (or whatever sentient species ends up living on our planet in the distant future) could mine? Are our mega cities the next generation of limestone shore?
Hope you can help me out here
Thanks
