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 (23º 55,5" S and 68º 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 Sánchez, 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.
