Indochinite Tektite | 40.2 Grams | Impactite Gormanite sphalerite and pyrite crystalsIndochinite is a variety of the mineral tektite, which is a natural glass formed by the intense heat and pressure of a meteorite impact. These tektites are usually found as small, aerodynamically shaped objects, often teardrop or irregular in shape, resulting from the molten material solidifying as it cooled rapidly after being ejected from the impact site. Indochinites are believed to have formed around 780,000 to 800,000 years ago, following a
