Research Abstract

In-situ carbon isotopic analyses using SIMS was developed at the University of Hawaii. I analyzed 4 different natural samples: (1) high-pressure metamorphic rocks, (2) contact metamorphic rocks, (3) jadeites, and (4) graphite-bearing mantle xenoliths. Unfortunately, I was not able to reliable date from (1) and (2) because of matrix effects of silicate inclusions within carbon-bearing phases in these samples. Graphite in jadeites has similar carbon isotopic compositions to mantle value. This suggests that fluids with mantle-like carbon isotopic compositions are responsible for the formation of jadeite at the beginning of subduction. Graphite in the mantle xenolith has light-carbon isotopic compositions. This suggest the carbon in the sample was of biogenic origin. This graphite will provide us useful information on origin of diamond in the mantle.
