Highly siderophile element geochemistry of peridotites and pyroxenites from Horní Bory, Bohemian Massif: Implications for HSE behaviour in subduction-related upper mantle

Original language description

Highly siderophile element (HSE - Re, Os, Ir, Ru, Rh, Pd, Pt, and Au) and S abundances, sulphide petrography and 187Os/188Os compositions of two distinct suites - Mg-lherzolite and Fe-dunite/wehrlite accompanied by pyroxenites from Horní Bory, Bohemian Massif, Czech Republic are reported. The Mg-lherzolite suite is enriched in IPGE (Os, Ir, and Ru), moderately depleted in Pd, Pt and S, and has osmium isotopic compositions similar to that of the Phanerozoic convecting mantle. Such a composition can be best explained by reaction between previously depleted peridotite and sulphur-undersaturated melt at low melt-rock ratios. This reaction was associated with precipitation of IPGE alloys and Pt-As. The Fe-dunite/wehrlite suite is depleted in IPGE, enrichedin Pd, Pt, and S and has radiogenic osmium isotopic compositions. The origin of this suite reflects melt-rock reaction between peridotite and subduction-related melt at high melt/rock ratios resulting in breakdown of primary sulphides and
