Maskelynite is a glassy phase found in some meteorites and meteorite impact craters. Typical samples are similar in composition to plagioclase feldspar, and revert to that mineral when melted and recrystallized. It was named after British geologist M.H.N. Story-Maskelyne.
The Dhofar 378 meteorite is 47% maskelynite by volume.
Usage examples of "maskelynite".
Shergotty and Zagami meteorites show that both diabase stones consist mainly of the pyroxenes pigeonite and augite, and of maskelynite, a shocked plasgioclase glass.
The maskelynite is zoned, with accessory phases of titanomagnetite, ilmenite, pyrrhotite, fayalite, trydimite, whitlockite, chloraptite, and baddeleyite.
