Tissintite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Ca,Na,□)AlSi2O6
Specific Gravity:
3.395 (Calculated)
Crystal System:
Monoclinic
Name:
The mineral name is after the host Tissint meteorite, which in turn is named after the town of Tissint, Morocco, where the meteorite fell. It fell on 18 July 2011 and is only the fifth Martian meteorite that people have witnessed falling to Earth.
Ca-analogue of jadeite. A C2/c clinopyroxene, containing 42–60 mol% of the Ca-Eskola component, by far the highest known.
A vacancy-rich, high-pressure clinopyroxene, with a composition essentially equivalent to plagioclase. Formed during a shock event severe enough to allow nucleation and growth of vacancy-rich clinopyroxene from a melt of not too calcic and not too sodic plagioclase composition that was neither too hot nor too cold (Ma et al. 2015), i.e. the meteor hit on Mars that ejected the meteorite material that reached earth.
