PGE and Chalcophile element concentrations in peridotitic sulfides from the St. Elena ophiolite, Costa Rica
This dataset presents in situ (LA-ICPMS; down to a 10 micron beam size) major, minor, PGEs and chalcophile elements on sulfides from five partially serpentinized peridotites from the St. Elena ophiolite, Costa Rica. PGE-Re concentrations in sulfides (dominant petlandites) are highly variable, ranging from 1 – 100,000 times that of primitive mantle (PM). PM-normalized PGE-Re patterns in the sulfides are dominated by strong Pt depletions relative to Os, Ir, Ru and Pd. Pb concentrations average around 2.7 ppm.
Coverage Scope: Regional (Continents, Oceans)
Geographic Location: St. Elena, Costa Rica
