Hola List Today I update my website http://www.meteorites.cl with impactites from monturaqui ($5-$8 each)
Monturaqui Impactites The meteoric crater of Monturaqui, located near to the south border of the Salar de Atacama (23� 55,5" S and 68� 15,6" W) and with altitude of 3000 m, was formed around 100,000 years ago by the impact of a iron meteorite (coarse octahedrite IA) of an estimated diameter of 13.4m and 9,870 ton. Which formed a crater of 380 m of diametre in the line E-W and 360m in the line N-S with a depth of 31m. Recognized the first time in 1962 by Joaquin S�nchez, from of the examination of an air photography. These Impactites are the most significative material of meteoric origin, in the crater and it consists of a minerals cluster highly heterogeneous, formed mainly for granitic minerals inside of glass that involves small Fe- Ni spheres, of sizes between some microns up to 2mm.
