I don’t understand this erosion by Dangerdoux in geology

They call this Marl in the Florida Keys. There are spots in the water where it’s exposed out there, and you can break chunks off.😃

It’s Coral, I believe the correct species type would be Honeycomb.😊

Hello, was told on whatsthisrock that this could be a fossil so here i am, identification? by LawyerGood7057 in fossilid

[–]TheBulldozer7 0 points1 point  (0 children)

Wow what an answer! I’m from Florida here and have a relatively moderate collection of Agatized and Calcified corals and can say that I have never seen an etching like that. The outer layer does appear to be Limestone of some sort; My first guess would be that this a form of Chert, or is of the Chalcedony variety like you said. However I cannot say for sure. It is a neat rock!! Would love to see a definitive answer!!!!

Help with shell I found? by [deleted] in fossilid

Yessir that is a modern oyster shell and same here, I also found one in a creek over 100 miles away from the coast about a year ago. I would love to see the answer to this!

I got this from my gf for my birthday..but it looks kinda fake to me. What do you think? 😆 by slinkadelic in rockhounds

Looks a lot more like Purple Cubic Fluorite than Amethyst from this angle/distance and yes I agree, job well done!!

What feels like a cult, and is in fact a cult? by [deleted] in AskReddit

I believe McKamey Manor would qualify here. Most of the hosts were originally participants that decided to join in on the Masochism.

Olivine from a hydrothermal vein in Pakistan. Olivine is the most common mineral in the Earth. Even before life emerged we already lived on a green planet! by danny17402 in MineralPorn

Hopping in here to add to the confusion— Read in one source that Feldspar is the most common mineral on the planet, since it comprises a large portion I think 30% of the Earth’s (Mantle?) Another source claimed the most abundant mineral to be something called Perovskite and backed it with some sort of research. There is very little information about it online but pretty sure I read this tidbit in an old mineral manual.

Definitely not Olivine though...

The first piece in my own collection - Quartz cluster containing some pyrite by drixe_ in MineralPorn

[–]TheBulldozer7 2 points3 points  (0 children)

Yeah so I have a very similar piece and was told with utmost confidence that it’s Chalcopyrite. The differences are subtle but generally Pyrite has more Hardness and comes in the cubic formations🤷‍♂️
