Carbon in Glass Inclusions in the Allende Meteorite
Abstract
It is shown that olivines in chondrules of the Allende CV3 carbonaceous chondrite contain two types of micron-sized silicate melt inclusions. These are clear glass (type I) and devitrified glass (type II) inclusions. In an attempt to detect the possible presence of carbon, various inclusions were measured with a Raman microscope. Carbon in the form of graphite was detected only in type II inclusions.
