Pseudotachylite often appears dark, shiny and glass-like. This rocks name looks similar to tachylyte basaltic rock. Tachylytes are made of molten basalt which cooled quickly and often contains crystals with a quench texture that formed due to rapid cooling after being heated up rapidly.

This combination pseudotachylite Beaverhead shatter cone was legally self-collected on expedition, in 2002, in a place named Law's Canyon, at the time, near Challis, Idaho. The main and auxilliary picture clearly shows the pseudotachylite injected (possibly troilite) into the rock and the back of this same specimen has evidence of shatter cones.

The specimen is unusual as it contains both elements of what scientist typically see occurs when the ground is suddenly impacted, heated and pressurized by a high speed meteorite/ asteroid strike.  

Specimen size: 11.25" L X 6 1/2" W X 4 1/2" D, Weight: 8.4 lb

Ships with Certificate of Authenticity, information about the specimen. Display stands and photo cube not included.

Here is a singular opportunity to own a very unique specimen from the famous Beaverhead impact structure, the 2nd largest impact structure in the USA!
