Abstract
The particular purpose of the present study was to remeasure (using the electron microprobe) and reevaluate the range of olivine compositions, including CaO, in dunite sample 72415, and compare that range with olivines in established plutonic rocks. Olivines from ferroan anorthosite 62237 and samples from the Stillwater intrusion were analyzed; literature data for other lunar and terrestrial plutonic samples were also used for comparisons.Downloaded from ADS
