The nickel sulfide mineralization of ultrabasic rocks in Bangong Lake-Nujiang metallogenic belt of western Qinghai-Tibet Plateau constitute a new type of ore deposit discovered in Tibet in recent years.Based on litho-geochemistry and a Sr-Pb isotopic analysis of the nickel-bearing ultrabasic rocks in the Bangong Lake within the west segment of the metallogenic belt,this paper describes the characteristics and formation conditions of magma sources of these rocks and,according to the zircon U-Pb LA-ICP-MS dating data,deals with the basement background of northwest Tibet.The results indicate that the Ni-bearing ultrabasic rocks are enriched in large-ion incompatible elements Rb,Th,U,Sr,Pb and high strength field element Ta but depleted in Ba,K(LILE) and Nb,Ti (HFSE) in the primitive mantle-normalized trace element patterns,exhibiting a strong REE depletion but a slight LREE enrichment in the chondrite-normalized REE patterns.All these features indicate consistently that the ore-bearing magma was derived from an enriched lithospheric mantle source which had been metasomatized by the subducted sedimentary melt,and that the magma originated from a source with low extent of partial melting (about 10%) at a shallow depth of the spinel lherzolite facies.In addition,a group of residual zircon ages of 2.48 Ga in the rocks indicates a relative simple source of sediments in the mid-Tethys ocean of Bangong Lake area at that time,which probably came mainly from the Late Archean-Early Proterozoic basement.It is thus inferred that the changing period from Archean to Proterozoic ( ca.2.5 Ga) might have been a rapid growing period of ancient continental crust in northwestern Tibet.
