摘要: 树基沟铜锌矿床是太古宙花岗-绿岩带中与火山岩有关的块状硫化物矿床(VMS)。本次对赋矿围岩黑云斜长角闪片麻岩开展了锆石LA-ICP-MS U-Pb定年,主量元素、微量元素和Hf同位素分析。锆石U-Pb定年结果表明,黑云斜长角闪片麻岩原岩结晶年龄为(2 549.4±5.6) Ma,可近似代表树基沟铜锌矿床成矿时代。地球化学研究表明,岩石富集大离子亲石元素(LILE)、亏损高场强元素(HFSE)、轻稀土富集、重稀土亏损,为一套岛弧环境的火山沉积岩。黑云斜长角闪片麻岩εHf(t)值为5.0~8.7,单阶段模式年龄TDM 1值为2 527~2 649 Ma,指示其源区主要亏损地幔物质,树基沟地区可能存在新太古代地壳增生事件。结合前人研究成果,认为树基沟铜锌矿床成矿于板块俯冲环境,地幔部分熔融形成富含贱金属岩浆向上运移、汇聚、喷发、固结成岩,后经海水淋滤下渗成矿元素富集二次喷发成矿,并经后期鞍山运动变质变形作用的产物。
