摘要
二里沟金矿床的含金石英脉产于二叠系炭质板岩中,金属矿物主要以硫化物为主,而金矿物主要赋存在黄铁矿中。流体包裹体均一温度范围为119.7℃~293.5℃,盐度范围在3.15wt%~8.66wt%,密度在0.92g/cm3左右,成矿流体具有中低温、低盐度、高密度的特征,结合前人研究,认为该矿床类型可能属于中低温的造山型矿床。
Containing gold quartz vein gold mine in Permian in carbonaceous slate in Erligou Gold Deposit, metal minerals are mainly composed of sulfide and gold content of ore deposits mainly occurs in the gold content of pyrite. Fluid inclusion homogenization temperature of 119.7 ℃ to 293.5 ℃, salinity range in 3.15 wt % - 8.66 wt%, the density of around 0.92 g/cm3. Suggests that the ore-forming fluid has the characteristics of low temperature,low salinity and high density. Combined with previous studies that the ore deposit types may belong to the low temperature of orogenic type deposit.
