中文摘要:新疆北部的铜镍(铂族元素)硫化物矿床成矿系列形成于海西期,是世界上形成于显生宙的少数几个铜镍硫化物矿床成矿系列之一。它具有许多特殊性,如形成多个亚系列(喀拉通克、黄山、箐布拉克)、每个亚系列又包含多个岩体形成多个矿床、不同的亚系列及每个亚系列内部的各个岩体和矿体差别较大、成矿母岩低镁高铝富钾等等。海西期的地幔柱活动可能是形成该成矿系列的主要原因。目前对同一时期的箐布拉克亚系列及其它基性超基性岩带的研究程度较低,在今后的大调查中应加以注意。
Abstract:Being one of the most important Phanerozoic Cu-Ni sulfide metallogenic series in the world, the Hercynian Cu-Ni sulfide metallogenic series in North Xinjiang has some unique peculiarities: ① one series is composed at least of three subseries; ② each subseries has more than three mineralized igneous complexes; ③ the subseries are different from each other; ④ the mineralized basic-ultrabasic rocks are characterized by low Mg and high Al and K. The interaction between the mantle plum e and the crust played an important role in the formation of the Kalatongke, the Huangshan-Hami, and the Qingbulake subseries of the Hercynian Cu-Ni sulfide metallogenic series, while the Qingbulake subseries has not been investigated thoroughly and has a potential for prospecting.
