Tektites found on Earth are formed by large asteroidal or cometary impact with the Earth. Energy from the impact melts terrestrial rock and ejects it into the upper reaches of the atmosphere. A few minutes later tektites rain down. The final morphologies are largely dependent on the distance from the source crater and the degree of terrestrial weathering/etching. Where are they found?Tektites are found in geographically restricted areas or 'strewn fields' related to the source crater. The most recent and largest strewn field is in Australasia with tektites being found in the Indochinese peninsula (Thailand, Vietnam, Cambodia, Laos and southern parts of China), the Philippines, Malaysia, Indonesia and Australia. These tektites are derived from an unknown crater in the Indochinese Peninsula area. The second largest strewn field is in North America, with tektites being found in Georgia and Texas, derived from the Chesapeake Crater in North America. The green moldavite tektites are found principally in the Czech Republic from the Ries Crater in Germany. Tektites are also found in the Ivory Coast, from the Bosumtwi Crater in Ghana. Numerous other tektite to impactite sites are found, usually associated with smaller craters. Sent with certificate, professionnal seller based in FranceCombine shipping available
