Highly siderophile element and Re-Os isotopic compositions of Mohelno-Biskoupky peridotite, Bohemian Massif, Czech Republic
2015
Abstrakt
We investigated major/trace element compositions in parallel with highly siderophile element (HSE) distributions and Os isotope compositions in ""Type I"" rapidly cooled garnet and spinel peridotites from Mohelno and Biskoupky, equilibrated in low P-T regime and most likely representing suboceanic mantle lithosphere. Based on the described behavior of the trace elements and HSE distribution, it is likely that Mohelno-Biskoupky undergone partial melting and subsequent refertilization by basaltic melts, the pattern which is usually recorded by orogenic lherzolites rather than abyssal peridotites.
