This is 1 of 169 approved meteorites classified as Martian (shergottite).

Olivine-phyric shergottite

WA 8716 was classified among the group of shergottites. One of the characteristics of the rock is to be rich in olivine. This mineral occurs both in the form of phenocrysts (measuring up to 2 mm) and smaller crystals, this time microscopic. Large olivine crystals and a population of microscopic crystals are zonated, with a more magnesian core and an iron-enriched perimeter. Other microcrystals appear on the contrary homogeneous. Small inclusions of chromite, as well as vitreous inclusions surrounded by radial fractures, can be observed in olivine crystals. The rest of the stone is made up of a matrix in which are housed crystals zoned with pyroxenes, plagioclases transformed into maskelynite, oxides (chromite, ilmenite), phosphates (chlorapatite) and finally sulphides (pyrrhotite). Surprisingly, some sulphides would be present here in the form of troilite, not pyrrhotite


Original mass : 168 grams, and is apparently paired with a set of fragments representing a much larger mass, weighing a total of 3.7 kilograms

Date of purchase : DEC 2014 . Ouarzazate. Morocco

Unknown place of fall
