摘要:

铜绿山矽卡岩型铜铁金矿床处于长江中下游铁铜成矿带最西部的鄂东南矿集区,主矿体分布于燕山期闪长岩与下三叠统大冶群大理岩、白云质大理岩接触断裂复合带上,矿体呈似层状、透镜状和脉状产出。在详细研究铜绿山矿床成矿地质背景以及野外系统采样的基础上,通过对石英二长闪长岩和不同成矿阶段(矽卡岩阶段、退化蚀变阶段、氧化物阶段、硫化物阶段和碳酸盐阶段)样品分别进行主量、微量和稀土元素的地球化学分析,从元素地球化学角度讨论成矿流体的地质特征。结果表明:在接触交代过程中,Fe、Mn等元素逐渐被成矿流体从岩体中带出,在构造的有利位置发生沉淀并富集; 当矿化强烈时,MgO含量急剧增高,CaO含量急剧降低,说明矿化可能与镁矽卡岩有关; Hf/Sm值从早期蚀变阶段普遍小于1变为晚期蚀变阶段普遍大于1,说明到了晚期蚀变阶段,成矿流体可能以富氟流体为主,野外观察到黄铜矿矿石往往产于透辉石矽卡岩以及晚期萤石脉切穿早期磁铁矿矿石现象也佐证了这一认识; 从石英二长闪长岩到不同成矿阶段样品,稀土元素总含量总体上呈逐渐降低的演化趋势,而退化蚀变阶段样品的稀土元素总含量普遍较高,不排除可能发生稀土元素矿化。

Abstract:

Tonglushan skarn-type Cu-Fe-Au deposit is located in the southeastern Hubei of the western Middle-lower Yangtze River Fe-Cu metallogenic belt. The main ore bodies of Tonglushan deposit distribute along the contacting zones and faults between Yanshanian diorites, and marbles and dolomitic marbles of Lower Triassic Daye Formation. Ore bodies occur as stratoid, lenticular and vein. Based on the detailed metallogenic geological background and systematic sampling, the quartz monzodiorite and mineral samples in different metallogenic stages, which are skarn, retrograde alteration, oxide, sulfide and carbonate stages, were analyzed by the major, trace and rare earth elements, and the geological characteristics of ore-forming fluids were discussed by element geochemistry. The results show that Fe and Mn are taken out from the fluid and deposit in the suitable position; the increase of MgO content and decrease of CaO content during the mineralization indicate that the mineralization may be related with magnesium skarn; the ratios of Hf/Sm change from less than 1 in the early metallogenic stage to more than 1 in the later metallogenic stage, implying mainly F-rich fluid in the later metallogenic stage, and the wide distribution of chalcopyrite ores in diopside skarns and fluorite veins cutting the former magnetite ores supports this conclusion; the total contents of REE decrease from the quartz monzodiorite to samples in different metallogenic stages, and the higher total contents of REE in retrograde alteration stage probably mean REE mineralization in it.
