Indochinite – Guangdong

Indochinites from Guangdong Province are tektites from southern China and belong to the extensive Australasian tektite strewn field. They formed approximately 788,000 years ago during a major impact event, when terrestrial rocks were melted and part of the resulting melt was ejected into the atmosphere.

Tektites from the Guangdong region are most commonly dark brown to almost black and have a glassy character. They occur in various shapes, and their surfaces may be strongly sculpted, with pits, grooves and other structures. Our selection primarily includes specimens from the Maoming area in Guangdong Province, China.

Indochinites and the Australasian Strewn Field

The Australasian strewn field is the largest known tektite strewn field on Earth. Tektites associated with this impact event are found across a vast area extending from southern China and Southeast Asia through Indonesia to Australia. Tektites from southern China represent one of its northern groups.

Although the age of the Australasian tektites is well established at approximately 788,000 years, the source crater of this impact event has not yet been conclusively identified. Research into their distribution, chemical composition and shapes nevertheless points to a source region in Southeast Asia.

Appearance of Tektites from Guangdong

Individual specimens can vary considerably in shape, size and surface structure. Irregular to aerodynamic forms with a dark glassy surface are typical. Some pieces may display brownish to olive shades when viewed in strong transmitted light.
