Just a collection of rocks! Also some punk (rock) and some queer geology resources! Most of the images on this blog probably won't be mine.
Here's how you can add an image:

Things you'll find on this blog:
Sedimentary rocks
Metamorphic rocks
Igneous rocks
The rock that I have been reading about today is called tuff. Some sources classify it as an igneous rock, some classify it as a sedimentary rock, others classify it as both! I'm putting it in the igneous category because it mostly consists of Volcanic material, and because according to wikipedia it's mostly studies as a part of igneous petrology. Tuff is really cool! Visually, at least in most of the photos I saw, it looks like a finer grained conglomerate. I've had a particular interest towards clastic rocks, and tuff is no exception! Even though it is an exceptional rock. According to the University of Pittsburgh Department of Geology and planetary science, "A rock with a pyroclastic texture is termed a tuff if the largest fragments are less than 2.5 inches long, a volcanic breccia if the fragments are larger."
According to the Geology Science website, its composition is felsic, which basically means that it's minerals are lighter (whereas mafic rocks tend to consist of darker minerals) {I think!}.
I'm really interested in learning more about the processes of how tuff forms, and will maybe make a second tuff entry when I do.
Nashite is a very interesting mineral.According to Mindat, its chemistry consists of the elements Ca (calcium), H (hydrogen), Na (Sodium), O (oxygen), and V (vanadium). It has been approved by the IMA. According to the University of Utah, it was first disvocered by Joe Marty in 2010 in San Miguel county, Colorado. Nashite is named after Dr. Barbara P Nash. You may be wondering why I have chose to put this entry in the Queer geology history/resources/representation box, and that is because Dr. Nash is a trans woman. She has done a lot of work related to minerals and volcanic rocks. This page has some of her publications listed if you would like to read some of her research ! I don't honestly know a ton about minerals (although I'm definitely interested in learning more about them), but it is really cool to know that there are Trans and LGBT geologists doing really interesting research!
