Description:
In this talk we discuss a simple physical disaggregation technique coupled with an X-ray mapping procedure used to locate 81 micrometer-sized presolar SiC grains from the Murchison carbonaceous chondrite, that preserves them in their pristine state. We then describe pristine SiC surface characteristics and overall morphologies determined by high resolution field emission scanning electron microscopy (FESEM), and compare these features to those of presolar SiC grains that have been prepared using chemical dissolution techniques.
