Petrified Lightning - 2.43" Saharan Fulgurite splitammonitepair These varied shades and hues

These varied shades and hues are the product of the ever-present geological forces always at work below our feet

Documented evidence of mining in this region dates back to the Spanish conquest

The red coating is actually a silicone adhesive called RTV 560

This specimen is a fragment of brick from the walkway of that home

When lightning strikes dry sand, the intense heat melts and fuses the silica creating tubes of rough glass called fulgurites. The process happens quickly, often trapping molecules from the surrounding atmosphere inside the walls of the impact tube. These natural time capsules allow scientists to study the composition of ancient climates. This specimen is a 2. 43" fulgurite collected in the Sahara Desert. Originally
