摘要

The analyses of PGE characteristics for the Kudi ophiolite, western Kunlun, are reported in this note. The Ir-depleted anomalous ancient upper mantle represented by the Kudi mantle peridotites had been percolated and mixed by remelted oceanic crust material from a supra-subduction zoen, leaving the rocks relatively enriched in Pd. The PGE contents in the Kudi cumulate pyroxenites and gabbros vary from 2.4 to 23.94 ng/g, and the highest values are in pyroxenites. The Pd/Ir ratios increase from the pyroxenites to the gabbros.
