Applications of the laser Raman microprobe to the study of layered intrusions

Abstract

Raman spectroscopy is a non-destructive technique that can be used for the identification and crystallographic analysis of both transparent and opaque minerals as small as 1-2 μm in diameter. The technique has advantages over analyses by other techniques such as X-ray diffraction and electron microprobe, because little sample preparation is required and samples ranging from hand specimens through polished blocks to thin sections can be rapidly analysed. These features make this an ideal technique for the identification and investigation of the various minerals associated with layered mafic-ultramafic intrusions such as the Archaean Munni Munni Complex, in the west Pilbara Block (WA). -Authors Show more
