Indochinite is
named after the region of occurrence; the former French
colonies of Indochina (Vietnam, Laos, Cambodia) but
also found in
Thailand and southern China. These Tektites are
usually dark brown to black natural glass.
Indochinites are similar to other Tektites such as Libyan Desert Glass
and Moldavite.
Tektites
may be Meteoric Silica Glass as a result of the impact
of a meteor on Earth. Tektites are usually found in
association with meteor impact craters or suspected
ancient craters. Their origin is not fully understood.
The leading theory, the "Meteorite Impact
Theory", is that when a meteorite hits the Earth,
the heat and pressure of the impact are so great that
it causes rock and sand to be fused into glass
or Tektites. Tektites, like all natural glasses, contain
gas bubbles and "swirl" like inclusions.
