This is a strange rock that I found inside a shipment of indochinite tektites from Thailand. This specimen was mixed in with over two kilograms of small tektites. It has the same shape and surface etching features seen on tektites, but it is heavier and grey in color. It appears to be a fine-grained rock of some sort that has experienced the same chemical weathering processes that indochinites recovered in the same area show. It is a tektite version of a meteorwrong, a "tekwrong" ?
