Chert- is a microcrystalline or cryptocrystalline sedimentary rock. 

Diorite- is a course grained, igneous rock.

A to Z Rocks

So I'm going to start out something fun. I'm going to list off rock specimens A through Z. Either going to try to get one in for each day or more than one a day. There are three different types of rock: Igneous, Sedimentary, and metamorphic rocks.

I'm going to start with the letter A of this specimen, Andesite.
Andesite is a fine-grained, extrusive igneous rock composed mostly of plagioclase with other minerals such as hornblende, pyroxene and biotite.

Hey everyone! This blog is and will be about Geology and Astronomy related material. Pictures will be posted along with text. This is new to me because I normally blog about my personal life and also about sports so this is kind of a different direction. It'll be a fun experience and journey for who ever follow! Thank you for taking the time to look at my blog! Enjoy!
