摘要
大坪金矿床属石英脉型多金属硫化物矿床.论文总结了最具代表性的V_9矿脉的地质特征,指出该矿脉深部找矿远景大.对流体包裹体研究表明,矿脉形成于中深(3.07km)、中压(922×10~5Pa)、成矿流体中温(264℃)、中盐度(9.05wt%NaCl)和中等密度(0.86g/cm^8)的物理—化学环境中.
Abstract: The Daping Gold Deposit belongs to a polymetallic deposit of gold-sulfide quartz vein type. The geological characteristics of the most representative vein No.9 are summed up; and the fine prospects in the deep of this vein is pointed out in this paper.The research on fluid enclosure shows that vein No.9 was formed in a physical-chemical environment where the depth and pressure were medium (3.07km, 921×10~5Pa),and the ore-forming fluids had medium temperature (264℃), medium salinity (9.05wt%NaCl) and medium density (0.86g/cm5).
