About XenoliteHide

Formula:
Al10Si8O31
An uncertain material, probably sillimanite.

Originally described by Nils Adolf Erik Nordenskiöld in 1842 from pebbles and boulders at Gulf of Finland coast near to St Petersburg, Leningradskaya Oblast', North-Western Region, Russia. Friedrich Becke investigated xenolite by optical methods and noted that it is very close to sillimanite.

Note: Not to be confused with xenolith.
