Abstract

Raman microprobe (RMP) spectra of synthetic coesiste and three natural coesites from eclogite - facies rocks are provided and evaluated for characterisation purposes. The main coesite line lies at 521 cm^-1 and the other characteristic lines attributed to coesite occur at 117, 177 and 271 cm^-1. Two petrologically useful applications were (a) the confirmation of the coesite structure in very small natural crystals deduced to be coesite from petrographic observations only, and (b) the recognition of sub-microscopic crystallites of quartz in incipiently - transformed coesite in all the natural samples.
