Description
Summary:The aim of the present contribution was to evaluate the trace element mobility in olivine, low-Ca pyroxene and plagioclase of the Kargapole meteorite under thermal or impact metamorphic conditions and recognition of the properties of chondrule-forming events. The compositions of the minerals were analyzed using an electron probe microanalyser (EPMA) and a secondary ion mass spectrometer (SIMS). No considerable deviations in the trace element concentrations of olivine and pyroxene from unequilibrated ordinary chondrites in the Kargapole meteorite were revealed. This points to minor effects of impact metamorphism and terrestrial weathering on trace element mobilization. Olivine and low-Ca pyroxene of porphyritic olivine-pyroxene chondrule POP-0 contain higher trace element concentrations than minerals in porphyritic olivine PO-2 and olivine-pyroxene POP-4 chondrules and in the meteorite matrix.
