This is a melted stony meteorite, or achondrite (sub-group: eucrite). It is part of the Stannern meteorite shower that fell in Moravia in May 1808. It has a mineralogy similar to that of a terrestrial basalt (igneous rock formed from cooling lava), made up of the silicate minerals pyroxene and plagioclase. Stannern is one of a group of meteorites that is thought to come from the asteroid 4 Vesta.
