| 英文摘要 | Ni-Cu sulfide mineralization occurred in series of mafic-ultramafic complexes in Eastern Tianshan. These deposits, however, failed to reach economic level for PGE, and some of the samples have lower PGE compositions even than primitive mantle. Low PGE contents can be caused in two ways: (1) sulfide segregation happens so early that a great deal PGE removed along with sulfide in the early stage of magma evolution; (2) because of low partial melting, large part of PGE remains in primitive mantle, so only little PGE goes into melt. In the case of Xiangshan and Tulargen, it is available to model the origin of primitive magma according to the geochemical behavior of PGE (luring partial melting and sulfide segregation. The results show that there is no sulfide segregation before the emplacement of the intrusions, and low degree of partial melting, about 10% to 20%, is responsible for the low PGE level in magma, for most of the PGE remains in the residual mantle after partial melting. Pd-Ni plot shows that no pre-segregation happened ever, and neither did sulfide fractionation happen. When R = 330, ( Pt + Pd) can reach 1. 27 x 10(-6) conduit system will be the most potential object to deposit PGE. |
