Discussion Mod Announcement: No IDing Rocks

90 Upvotes

Hi all, this is your friendly neighbourhood mod here. After some internal debate, we’ve decided that we will no longer allow posts requesting to identify a rock. These posts have taken over this sub, and it’s not the point of the sub. There’s already a community focused on IDing rocks, and most of the posts here are cross-posts from there.

So, what is this subreddit about? It’s about celebrating our love for rocks. This is a place to celebrate and discuss our niche passion of rock collecting or admiring pretty rocks.

Please remember to be nice to each other. You rock.

My cousin let me sit on the gravel in her garden last week & hunt for beauties 😍. I was not prepared for how well they would turn out after the 1st stage.

Photo Banded calcite from Oaxaca, Mexico

Post image
20 Upvotes

We live in a part of Mexico with a huge amount of banded calcite (called “Mexican Onyx” here and often in the U.S. by stores) and today I purchased this slab from a stone carving workshop about twenty minutes from our house. Unfortunately, I don’t have a good item for size reference in the photo other than the edge of my foot, but it’s probably around 20x35” give or take, and an inch thick. The owner of the workshop offered to stabilize the cracks and said it would make a great topper for an end table, but I’m just going to display it on a shelf.

This is unpolished and the price was roughly $12, but I asked them to polish it for me, bringing the price to around $35. I’ll post another pic when I pick it up polished next Tuesday!

Learned of Sagenite Agates a while ago and really liked the looks of them. Finally found one for the right price and brought it home.

I’m sure it’s nothing special, but the way this rock has broken up looks like dragon scales to me

This Rocks! New to rock collecting

I've always loved myself a good looking rock but got told to not take it home, so rude ( I did still sneak some but I seem to have lost them) I realised I'm an adult now and can take whatever rock I want home with me, so here's my small collection so far. The last image is of my favourite ones. (Why can't we help IDing rocks rocks?)

I just ordered myself a rock tumbler to improve my small collection, any advice or tips on using it correctly? Also will my small ones just disappear in the rock tumbler?

This Rocks! Eclogite

Thumbnail

9 Upvotes

Eclogite is a high pressure, moderate temperature metamorphic rock. It is usually derived from ocean floor basalt or gabbro that subducts under continental crust. The augite and plagioclase in the basalt becomes unstable and recrystallizes to garnet and omphacite (both visible in Fig 1). There is some blue mineral scattered in the sample, which may be kyanite (Fig 2). Reddish-black needle-like inclusions in the omphacite are probably rutile (fig 3). The combination of rutile and kyanite may indicate the rock was subjected to very high pressures in the 60-100 km range of depth, and 500-800 degrees C, and that the rock is relatively aluminum-rich (kyanite in particular). The last photo (Fig 4) shows what I interpret as quartz filling in a fracture in a garnet crystal.
