a specimen of spodumene from Moylisha, near Shillelagh, Co. Wicklow, Ireland a lithium aluminium silicate
|Origin||Moylisha, near Shillelagh, Co. Wicklow, Ireland|
a pyroxene mineral consisting of lithium aluminium inosilicate, LiAl(SiO3)2, and is a source of lithium.
Spodumene was first described in 1800 for an occurrence in the type locality in Utö, Södermanland, Sweden. It was discovered by Brazilian naturalist Jose Bonifacio de Andrada e Silva. The name is derived from the Greek spodumenos (σποδυμενος), meaning “burnt to ashes,” owing to the opaque, ash-grey appearance of material refined for use in industry.
