Sometimes the energy produced by a meteorite impact is sufficient to melt the Earth’s crust. The resulting droplets of molten rock are thrown high into the air and freeze as they fall. Splattering the surrounding area with droplets of glass called tektites.
This one is called an Indochinite, after the area in which similar tektites are found. Tektites look superficially similar to volcanic glass, or Obsidian, but are formed in a completely different way.
