Pyroxene
Pyroxene
Pyroxene is derived from the Ancient Greek πῦρ, pur and ξένος, xenos ("fire" and "strange"). This name was given in 1796 by Rene Just Haüy. This is due to the occurrence in volcanic lavas where pyroxenes are sometimes embedded as crystals in the surrounding volcanic glass.
It was supposed to be imperfections in the glass, hence the name "fire strangers". However, they are early-forming minerals that according to the Bowen reaction series have already crystallized before the magma reaches the surface of the earth (and from then on is called lava). In this way the pyroxene crystals "float" in the melt that forms the volcanic glass, or obsidian by rapid cooling.
