| 英文摘要 | The Xiangshan Cu-Ni deposit is located in the eastern part of the East Tianshan orogenic belt, northwestern China. Rhenium and osmium isotopic analyses of Ni- and Cu-bearing pentlandite from the deposit have been used to determine the timing of mineralization, the source of osmium, and, by inference, the source of ore metals. Pentlandite samples have osmium and rhenium concentrations varying in the ranges of 39.61 similar to 110.60 ppb, and 0.437 similar to 3.763 ppb, respectively. Analyses of these data yield a seven-point isochron with an age of 298 +/- 7.1 Ma. The age implies that the Cu-Ni sulfide deposit and other related magmatic deposits in the same area formed between the latest Carboniferous and Early Permian extension in the East Tianshan. An initial (187)Os/(188)Os ratio of 0.682 +/- 0.32 (MSWD=9.4) and the delta(34)S of -0.84 parts per thousand to +2.40 parts per thousand for the ores, suggests a magmatic source for the ores, with the melts being dominated by mantle contributions. The data also indicate that the Xiangshan Ni-Cu deposit, like many other silver, iron, copper, gold, and nickel deposits within East Tianshan, is related to a large-scale extensional process. |
