abstract |
Previous studies have identified iso-topic hotspots in insoluble organic matter (IOM)
from carbonaceous chondrites. The origins and formation mechanisms of these hotspots
and the host IOM are a matter of ongoing debate. For example, it is not clear whether
D and <sup>15</sup>N enrichments in IOM formed within a common organic precursor in
cold interstellar environments or due to irradiation of organic material in the early
Solar System. It is also unclear what effect parent body processes would have had
with regard to the alteration of meteoritic IOM. In order to address these issues,
more recent studies have attempted to make in-situ measurements of isotopic anomalies
in IOM. In this study we present in-situ NanoSIMS isotopic analyses of material within
a sample of the CM2 meteorite Cold Bokkeveld, comparing the distribution of hotspots
and bulk H, C and N isotopic composition in the rims and interiors of altered chondrules. |
