Fluid induced melting in mantle xenoliths and some implications for the continental lithospheric mantle from the Minusinsk Region (Khakasia, southern Siberia)

Kovacs, Istvan; Hidas, Karoly; Hermann, Joerg; Sharygin, Victor; Szabo, Csaba; Ntaflos, Theodoros


Eleven representative xenoliths from the Minnsinsk Region, southern Russia were studied in order to highlight the characteristic features of the subcontinental lithospheric mantle beneath the region. Type-I xenoliths show that the lithosphere underwent various degree of depletion overprinted by enrichment processes leading to LREE-enriched pyroxenes. Estimated equilibrium temperature for the xenoliths is in the range of 960-1050°C. Type-II xenoliths are the result of crystallization from a...[Show more]
