Gold in Quartz Matrix.

If I am not mistaken, this specimen originated from Colorado!

This is one of the largest uncut emeralds discovered as of yet!

Hello reader,

I was wondering if you’d would like to see more regular posts from me. Let me know what you think! I will try my best to maintain a consistent schedule, but I also have a very busy schedule.

Best,

This is a thin section photomicrograph of one of the lunar mare basalts that was sampled on the Apollo 12 mission. Notice the high olivine content! You can discover some more about this sample by using its identifier, located in the top left corner. Enjoy!

(Let me know if you’d like to see an annotated version)!

Also- quick revision- the field of view is actually 1 mm.

ROCK ON!

This is a cool shot that I got while visiting Carlsbad Caverns National Park in New Mexico.

Pictured above are photomicrographs of thin sections from the Manson impact structure (located in Manson, Iowa) seen through polarized light and crossed nickels. The first photo displays what I believe may be a silicate (feldspar, plagioclase) grain that exhibits the parallel striae of planar deformation features characteristic of shock metamorphism. The second photo depicts the annotations that I made to the original photomicrograph to highlight areas of interest. As seen in the second photograph, there is an extinction front captured in this image. Many silicate minerals that experience shock metamorphism after a collision may exhibit undulatory extinction, where the anisotropic nature of the crystal itself is not simultaneously experienced but rather is progressively expressed due to the irregularity created by the massive impact from a meteor. I don’t believe that there are many published photomicrographs of these thin sections, so this is a rare and special treat for anyone interested in geology, microscopy, meteoritics, or the wider field of astronomy. Enjoy! :^) [Please, if you have any comments, suggestions, or corrections for my work, leave them on this post!]

Will this be a new Steven Universe meme? Who knows... (Sorry for my awful art).

Here is a photo that I took at a museum of natural history in Houston, Texas. This is a specimen of cubic Fluorite. I apologize for the poor image quality! :^)

Crash Landing in Tumblr

Hello! I finally decided to get a tumblr! I hope to upload photos of minerals and little art pieces to this blog! Thanks for checking this out!
