摘要
通过近1000个包裹体温度、盐度的测定,圈出了该金矿Ⅱ_下脉中包裹体的温度、盐度及密度等值线图。等值线表现出与切割层间断裂的断层及富矿体有密切关系,反映了该金矿的热液成因及矿液的通道。文中还对矿物包裹体成分进行了研究,并且提出了该金矿属于中偏低温、低盐度、低密度的层控变质热液矿床观点。
Nearly 1000 inclusions from gold ores were measured for temperatures and salinities. On the basis of the data obtained, the isograms of temperature, salinity and density have been constructed for inclusions from the lower part of vein II in this gold deposit. The isograms indicate that the gold deposit is closely related to the faults which cut through the interlayered faults, as well as to the high-grade orebody, providing evidence suggesting the gold deposit to be of hydrothermal origin. Presented in this paper are the data on the composition of mineral inclusions, and a hypothesis has been proposed that the gold deposit is a meso-cpithenial strata-bound deposit of metamorphic-hydrothermal origin, which is charactenized by low salinity and low density.
