XL, TEKTITE -impact of METEORITE- 800,000 years!!! Polished. - 76.3 g

Las tektitas (del griego tektos, fundido) son objetos de vidrio natural que se han formado por el impacto de grandes meteoritos en la superficie de la Tierra. Las tectitas son los minerales más secos conocidos, con un contenido de agua promedio de 0,005%. Esto es muy raro, ya que la mayoría de los cráteres donde las tectitas se formaron se encontraban bajo el agua antes del impacto. También se ha descubierto zircón parcialmente fundido dentro de algunas tectitas. Esto, junto con el contenido de agua, sugiere que las tectitas se formaron bajo una temperatura y presión muy elevadas (similares a las necesarias para formar diamante). Las indochinitas como la de este lote se formaron por el impacto de un gran meteorito hace 800.000 años, en lo que hoy es el actual Laos, según muestran los estudios más recientes. El choque fue brutal, de manera que material fundido cubrió el 10% de la superficie terrestre, habiéndose encontrado indochinitas incluso en la Antártida. El ejemplar de este lote es de buen tamaño, bonita forma, y pulido perfecto. No deje escapar esta oportunidad!

Tektites (from the Greek tektos, molten) are naturally occurring glass objects that have been formed by the impact of large meteorites on the Earth's surface. Tektites are the driest known minerals, with an average water content of 0.005%. This is very rare, as most of the craters where tektites formed were under water prior to the impact. Partially molten zircon has also been discovered within some tektites. This, together with the water content, suggests that the tektites were formed under very high temperature and pressure (similar to that needed to form diamond).

Indochinites like the one in this batch were formed by the impact of a large meteorite 800,000 years ago, in what is now Laos, according to the most recent studies. The impact was brutal, so much so that molten material covered 10% of the Earth's surface, and indochinites have even been found in Antarctica.

The specimen from this lot is a good size, nice shape, and perfect finish. Don't miss this opportunity!
