新疆兴地Ⅱ号铜镍矿床位于库鲁克塔格前寒武纪基底陆壳隆起带南部，兴地深大断裂南侧，产于兴地Ⅱ号基性-超基性杂岩体内．本文通过对兴地Ⅱ号杂岩体中辉长岩进行LA-ICPMS锆石U-Pb精确定年，获得206Pb/238U加权平均年龄为740.2±5.7Ma，表明兴地Ⅱ号铜镍矿（基性-超基性杂岩体）形成于新元古代南华纪．对兴地Ⅱ号含铜镍杂岩体的年代学研究，为揭示兴地Ⅱ号铜镍矿床的成矿动力学背景，以及进一步寻找和深入研究区域内同类矿床具有重要的理论依据.

The Xinjiang Xingdi No. ⅡCu-Ni deposit prouduced in Xingdi No. Ⅱmafic-ultrmafic complex rock body which is located in the south of the continental crust uplift of Kuruktag Precambrian basement and the south Xingdi deep faults. A gabbro sample yielded a SIMS U-Pb zircon age of 740.2±5.7Ma(MSWD=0.85, 95% confidence level), which indicates that the Xingdi No. ⅡCu-Ni deposit(mafic-ultramafic complex) formed during the Nanhua period. It’s provide a theoretical basis to study the ore-forming era of the Xingdi No. ⅡCu-Ni deposit’s for the further seek and in-depth studies on the deposit.
