New Martian Meteorite
NEW MARTIAN METEORITE
Tissint – Achondrite (Martian, olivine-phyric shergottite)
The Tissint meteorite fall of 2011 is spectacularly significant: not only was it the first witnessed fall of a Martian meteorite in almost fifty years, but the few fragments that were swiftly recovered, less than 10kg worth, were fantastically uncontaminated by contact with the Earth and lack of weathering. The large mass held by the London Museum of Natural History is regarded as one of the most significant meteorites in their collection, and the most important meteorite of the last 100 years. This superb little nugget is a broken off end piece from a larger mass, with a rich black fusion crust, shimmering in places with a glass-like sheen. The rest of the stone displays the fine-grained, soft gray interior, a fascinating window into the mineralogy of the Red Planet, and representative of one of the most important meteoritic events for generations, measuring 28 x 22 x 19 mm, and weighing 12.9g, presented in a Riker mount.
