哈勒尕提铁铜多金属矿床是新疆西天山北缘博罗科努多金属成矿带上的一个典型矽卡岩矿床,其成岩成矿时代此前尚无确切的年代学资料。作者通过对与成矿相关的二长花岗岩和花岗闪长岩中锆石的LA-ICP-MS U-Pb同位素测定,获得其加权平均年龄分别为(376.4±3.2)Ma和(365.6±3.5)Ma,表明其侵入时代为晚泥盆世,代表了晚古生代北天山洋向南部伊犁板块俯冲消减背景下的岩浆作用产物。矽卡岩矿石中辉钼矿Re-Os等时线年龄为(368.9±3.1)Ma,加权平均年龄为(366±2)Ma,与成岩时代在误差范围内一致。哈勒尕提矿床与同一成矿带上的艾木斯呆依"可克萨拉铁铜矿床、莱历斯高尔-3571铜钼矿床等一起,构成了一个与晚泥盆世—早石炭世中酸性侵入岩有关的矽卡岩-斑岩型铁铜钼多金属成矿系统。
Halletti iron-copper polymetallic deposit is a typical skarn deposit on the Borokonu polymetallic metallogenic belt on the northern margin of western Tianshan, Xinjiang. There was no exact chronological data for the age of diagenesis and mineralization. Based on the LA-ICP-MS U-Pb isotopic measurements of zircons from monzogranites and granodiorites related to metallogenesis, the authors obtained the weighted average ages of (376.4 ± 3.2) Ma and (365.6 ± 3.5) ) Ma, indicating that the age of its invasion was Late Devonian, representing the product of magmatism under the background of the subduction of the northern Tianshan Ocean to the southern Ili plate in the Late Paleozoic. The Re-Os isochron age of molybdenite in skarn ore is (368.9 ± 3.1) Ma and the weighted average age is (366 ± 2) Ma, which is consistent with the diagenetic age within the error range. The Halle Gaiti deposit and the Aiamusi deposit on the same metallogenic belt together form a basin with the late Devonian- Skarn - porphyry iron, copper, molybdenum polymetallic metallogenic system related to the Early Carboniferous intermediate - acid intrusive rocks.
