Single and multiphase inclusions in metapelitic garnets of the Rhodope Metamorphic Province, NE Greece.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 73(3) , 477-83, (2009) Single and multiphase inclusions in garnet porphyroblasts from the diamond-bearing pelitic gneisses were studied by means of combined Raman Spectroscopy and Electron Scanning Microscopy (SEM/EDX). They are either randomly distributed or with preferred orienta... |
