四川省冕宁县石官山地区石英脉及包裹体特征

Characters of Quarts Vein and Its Inclusions in Shiguanshan Field,Mianning County,Sichuan Province

总结四川省冕宁县石官山地区石英脉的野外产出特征,描述了包裹体的显微特征,计算了石英包裹体的均一温度、盐度、密度,对石官山地区进行了野外地质调查并室内测试分析.结果表明,石官山地区包裹体盐度为8%~15%,均一温度为140~235℃,密度为0.98%~1.08%.这与冕西金矿集中区已发现金矿体有相似的成矿物化条件,具有找矿的潜力.

The characteristics of quarts vein were summarized, the microscopic characteristics of its inclusions were de- scribed, the homogenization temperature, salinity, and density of inclusions from quarts vein in Shiguanshan field were cal- culated, which located in Mianning County, Sichuan Province. The results show that the homogenization temperature is 140 -235℃, the salinity is 8% - 15%, and the density is 0. 98% - 1.08%, which indicate Shiguanshan field, with ore-pros- pecting potential, has similar ore-forming physicochemical conditions with other gold deposits found in the west of gold con- centration district in Mianning County.
