Timing and genesis of the Tongshanling stratiform W-Mo skarn deposit in Hunan Province: Implications for exploration

  • 摘要:

    湖南铜山岭矿床位于南岭成矿带西段, 是与Ⅰ型花岗闪长岩有关的矽卡岩型铜多金属矿床。近年在远离花岗闪长岩体的棋梓桥组灰岩地层中发现了厚层状矽卡岩型钨钼矿体, 其地质特征、矿物组合与金属类型均与岩体接触带型矿体不同。通过系统的野外观察、显微鉴定、石榴石原位U-Pb定年、白钨矿LA-ICP-MS微量元素分析对该矿床矽卡岩形成时代、成因机制进行了研究。结果表明: (1)矽卡岩成矿作用可划分为石榴石矽卡岩、绿帘石绿泥石矽卡岩、石英硫化物、石英方解石4个阶段; (2)石榴石U-Pb谐和年龄为(160.4±4.2) Ma(MSWD=0.79), 明显晚于花岗闪长岩体(约167 Ma), 与花岗斑岩(约161 Ma)的年龄一致; (3)核部石榴石稀土元素配分型式为轻稀土元素富集、重稀土元素平坦型, 与花岗斑岩全岩稀土元素配分型式相似, 边缘石榴石的稀土元素配分型式为轻稀土元素亏损、重稀土元素平坦型, 与接触带矽卡岩中石榴石不同; (4)与绿帘石共生的白钨矿主要可分为3个世代, 3个世代的白钨矿稀土元素配分型式均为轻稀土元素富集、重稀土元素亏损型, 但稀土元素总质量分数从第一阶段(Sch1-a, 332×10-6~353×10-6)到第二阶段(Sch1-b, 144×10-6~301×10-6)到第三阶段(Sch1-c, 4.05×10-6~31.8×10-6)呈显著渐进式下降趋势, 与绿泥石共生的白钨矿(Sch2)稀土元素配分型式显示轻稀土元素富集, 重稀土元素亏损, 稀土元素总质量分数为51.2×10-6~139×10-6; (5)钨钼矿化主要集中在退变质阶段, 其中Sch1-b及Sch2阶段具有较高的氧逸度, 为钨沉淀的主要阶段, Sch1-a与Sch1-c阶段氧逸度较低, 为钼沉淀的主要阶段。综合分析认为, 层状矽卡岩与铜山岭及魏家接触带矽卡岩均不为同一成矿系统, 可能与分异程度更高的花岗斑岩有关, 未来铜山岭矿床深边部找矿应该更加关注晚期花岗斑岩体。
