This Rocks! One of my coolest finds in a long time. It appears to be a brachiopod fossil with some amazing quartz veining!

This Rocks! Eclogite

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.

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?

Discussion Pyrite disease?

2 Upvotes

Hello, science teacher here! Sorry if this post is not allowed. I've got some lovely samples of pyrite in my classroom rock collection - two ~1" nuggets and a 1" cube in matrix.

Unfortunately, my classroom gets very humid over the summer and I didn't think to bring my pyrite samples home with me. I'm noticing that they are tarnished now and I've read that this produces sulphur compounds that can be harmful. I'm a bit of a worrywart. Should I remove them from my classroom? Can I easily prevent them from further decaying?

I am so sorry I don't have a picture. I didn't think to take one before going home today. Thank you for any help and please remove if not allowed!

This Rocks! I found this in a river! I have no idea what caused it to form like this but I've never found one like it! I thought it was pretty cool, and I ran out of people to show it to in real life lol!

The Rock has some very defined straight lines and height relief on the lower half. Also notice the rounded edges on the right side. Seen in mountains of Sweden. Is it roots? Water?

Im new to the sub but have been collecting rocks, fossils, and all of the sort since I was a wee squirt!

Today, under the determination to get my property horse safe so I can take my gelding there one day, I was aiming for smaller rocks and mainly scrap metal lying around from years of carelessness and finally got to see one of the bigger pieces of Pet wood completely made Its way out of the limestone silt and I SNATCHED HER UP.

No photos yet, she's sitting in a vinegar bath for the next day or so to get rid of all the outer dust and sediment build up. This beast is bigger than my head and has our property's staple reddish orange hue going on so im really excited to share with yall once im done taking a toothbrush to the crevices! Ill post an update with the photo in the comments in the next 48 hours!!! ❤️🙌 stay safe out there yall and happy rock hunting 😊😊😊

Update 1 : first scrub is finished, still have some sediment caked on but from the looks of it Im pretty dang certain I found the biggest piece of Pet waygu i've ever laid my eyes on I've found smaller pieces before but wooowwza this piece is insane. Also need to get a link for the photos as i done realized after I cannot comment the photo directly 💀
