NWA 10458, L5 Chondrite with LITE Inclusions, Micromount

$5.00

Description

The meteorite NWA 10458 was recovered out of the Saharan Desert near the border between Morocco and Algeria in 2014. Unlike many desert meteorites, this find was relatively fresh, which is evident it's dark black fusion crust. This meteorite was classified as an L5 chondrite that is moderately shocked (S3) and lightly weathered (W1). What makes this meteorite very interesting is the presence of LITE inclusions - Large Igneous Textured Enclaves. LITE's are a new type of chondritic inclusion which was discovered by the scientists at Cascadia Meteorite Laboratory (Portland State University). These new inclusions have been published in scientific papers and are still being studied - further research will elaborate on how they were created and what their significance is.

Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing a single small fragment like the one shown. Your purchase will include a labeled gemjar for safe storage.
