Re-Os geochemistry of wolframite from Jeřmanice W-(Sn) mineralization, Bohemian Massif, Czech Republic
Original language description
We present the preliminary Re-Os data from W-(Sn) granite-related mineralization hosted in phyllites near Jeřmanice, Bohemian Massif, Czech Republic. Analyzed samples JerB-1 and JerC-1 have very low Re and Os contents (23 and 54 ppt; 0.15 and 0.5 ppb, respectively) coupled with surprisingly strongly subchondritic 187Os/188Os between 0.1040 and 0.1054. These preliminary results may suggest unique behavior of wolframite with respect to Re-Os isotopic system. While the Os contents are similar to terrestrial basalts (e.g., MORB etc.), it shows much lower Re contents and 187Os/188Os similar to Martian meteorites (SNC) and Eucrite Nuevo Laredo. Therefore, it is possible that wolframites have a potential to retain primary, frozen Re-Os composition reflectingRe-Os composition of the primordial Earth?s mantle.
