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.

Campo del Cielo iron meteorite. Structural classification is coarse octahedrite. Weight is 3 kilograms. This photo shows wonderfully developed regmaglypts, also referred to as “thumbprints”. The regmaglypts formed while the meteoroid ablated during passage through the atmosphere. The Campo del Cielo meteorites come from Argentina, where they are believed to have fallen between 4,000 and 5,000 years ago. Nickel-iron meteorites, such as this one, are fragments of the cores of larger ancient asteroids (similar to Earths iron core), that have been shattered by impacts with other asteroids. After spending 4,500 million years in space this piece of ancient iron core found its way to Earth from the asteroid belt between Mars and Jupiter.
