#Metamorphic Rocks

[geologyin-blog]

Weathering is the process by which rocks are broken down into smaller particles through physical, chemical, and biological processes. Weathering affects different types of rocks in various ways. Read more here: https://www.geologyin.com/2024/07/weathering-of-different-rock-types.html

Trivia Tuesday!

Do you know what metamorphosed quartz is called?

High-grade metamorphic rock, monomineral, most likely sillimanite crystals, more than 700 c and 7 kilo bars

Metamorphic: this rock is classified by grade. Low grade (like shale) means it was under a little pressure or only under pressure for a short time. High grade (like gneiss) was under a lot of pressure for a long time. When it's high grade the minerals can start to sort and rearrange themselves. High grade pressure can also take the minerals in its rock and make new gems out of it.

Break it

Melt it

To my geology gang out there who has any idea how to start studying for petrology, can anyone maybe send sum helpful tips, pdfs, materials that are free online, videos, and all that stuff.

This is for a petty thing I'm about to do to prove shit to people. Thank y'all in advance (⁠*⁠＾⁠3⁠＾⁠)⁠/⁠～⁠♡

I’ve handled a lot of Indiana river rock recently. These are a few I saved. I have a life long fascination with geology, Indiana has much to explore. The last two rocks give me comfort when I hold them. I don’t know why but I aim to find out!

Rocks are naturally occurring solid aggregates of minerals or mineraloids. They are classified into three main types based on their formation processes: igneous, sedimentary, and metamorphic rocks.

Micaceous Marble? Calcareous Schist? Sometimes metamorphic rocks aren't so cut-and-dry.

i think about how log 11 is kaycee being sad she will never get to show off her mod and having daydreams about being praised and recognized for her work, but in the end her one and only witness to her pride and joy was leshy, and the memory of what she has done and contributed to the game died with him

Metamorphic: this rock is harder than the rock it was made from. When put under enough pressure metamorphic rocks can make new gems or structures.

Break it

Melt it

Put under more pressure
