摘要
从区域铜镍矿成矿地质背景、矿区地球物理、地球化学特征等方面入手,对图拉尔根①号杂岩体进行岩相、岩石化学特征及矿化蚀变分析,与黄山、香山成型矿床进行对比.证实①号杂岩体岩石组合类型与香山、黄山闪长岩-辉长岩-辉石岩-橄榄岩型岩石组合相当,并具有相似的m/f、Ni/Co及较高的S值含量.矿化主要赋存在角闪橄辉岩相中,主要受杂岩体岩相带及岩相接触带间脆-韧性构造破碎带控制,认为该岩体具有形成岩浆型铜镍矿的成矿远景.
Starting from regional geological background of the Cu-Ni deposit and its geophysical and geochemical characteristics, this paper describes the petrological, petrochemical, minieralisation and alteration features of the No. 1 complex at Tulaergen, Hami County, Xinjiang Uygur Autonomous Region. A comparison has been made between these features and those of the deposits at Huangshan and Xiangshan. The results indicate that this complex is comparable to the Huangshan complex in their diorite-gabbro-pyroxene peridotite assemblage, m/f and Ni/Co ratios, and high S content. Mineralisation of this complex occurs mainly in amphibole pyroxene peridotite, and is controlled by certain lithological zones and britle-ductile fractured zones between different rock types. It proposess that this complex is a promising target of searching for Cu-Ni ores.
