Electron Microscopic Study of Carbon Minerals and its Application to Antarctic Carbonaceous Chondrite(<Special issue>Mineralogy-Micro to Global- (Part2))

Abstract

Mineralogy of various carbon minerals, such as diamond, graphite, fullerene, carbon nanotubes and shungite was briefly summarized and related studies were reviewed. Some typical occurences of nano-daiamond, graphite and other carbon aggregates in Antarctic carbonaceous chondrite were described by means of high resolution electron microscope. Their characteristic features were clarified.. It was suggested that carbonaceous chondrites may be classified into some types based on crystallinity of graphite and other characteristics of carbon minerals.
