摘要
对漠滨金矿流体包裹体的最新研究,获得成矿流体物理化学参数:平均均一温度为199.14℃,平均盐度为6.01wt%(NaCl),平均密度为0.92g/cm3。据此估算,漠滨金矿的平均成矿压力为16.36Mpa,平均成矿深度为1.64km。结合地质特征分析和前人的研究结果,认为漠滨金矿属于造山型金矿床的浅成类型,并推断漠滨金矿深部找矿潜力较小。
According to the recent research of fluid inclusions in Mobin gold deposit, the authors obtained physical and chemical parameters about metallogenic fluids： average homogeneous temperature is 199. 14℃, average salinity is 6. 01wt% （ NaCl）, and average density is 0. 92 g/cm^3. Thus, the average ore-forming pressure is estimated as 16.36 Mpa, and the average ore-forming depth is as 1.64 km. Combining with the analysis of geological characteristics and the previous results, the authors consider that it belongs to the epizonal in type of orogenic gold deposit, and the prospecting potential is little in the depth in Mobin gold deposit.
