Hi. My name is Andy. I'm a geologist from Canada who has been collecting minerals for decades and now I have added meteorite collecting to my hobby. This blog is loaded with photos of my personal collection of minerals and meteorites. I have also been adding my own photos of what I think is cool and interesting geology. Unless I indicate otherwise, all the microscope photos and macro photos have been taken by myself. Please use the "Ask me anything" option to leave comments or questions. I'd love to hear from you.

OBSIDIAN with CRISTOBALITE. Black obsidian (volcanic glass) with white “snowflake” crystals of the silica mineral, cristobalite. This combination is often referred to as “snowflake obsidian”. Microscope photo taken at 20X.
