Indochinite tektites were formed during an ancient meteorite impact on Earth. Molten debris from the catastrophic impact was thrown high into the atmosphere and then fell back to Earth as odd glass-like objects. The objects are called tektites and these particular tektites come from Thailand (hence the name Indochinite). Each tektite is unique and could be considered a fossil object. Their composition is very strange - not quite Earthly, but not quite meteorite either.
