Magnesio-hastingsite from the anorthosites of Oddanchatram, Palni-Dindigul area, Tamil Nadu

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

The characteristic mafic constituent of the anorthosites of Oddanchatram is clinoamphibole. The chemical composition, optical properties and cell parameters indicate it to be magnesio-hastingsite. It is suggested that the mineral is of primary origin and precipitated early from a hydrous gabbroic anorthosite magma that gave rise to the anorthositic suite of rocks of the area.
