河北青龙三家子金矿矿物学特征

研究了三家子金矿床中石英热发光性与包裹体均一温度、黄铁矿与热电性、金银矿物成分与成色等矿物学特征。在此基础上 ,总结了它们在判断矿床成因、矿床勘查与评价等方面的地质意义。最后得出结论 :三家子金矿为一中温、中深成热液矿床 ;尽管三家子矿床遭受到一定程度的剥蚀 ,但其深部可能还有较大的矿化远景。

Mineralogical characteristics of the Sanjiazi gold deposit in Qinglong county, Hebei

On the basis of studies of the mineralogical characteristics such as thermoluminescence and inclusion homogenization temperatures of quartz, pyroelectricity of pyrite and chemical compositions of gold and silver minerals and finenesses of gold and silver in the Sanjiazi gold deposit, the authors summarize the geological significance in the determination of the genesis of the deposit and mineral exploration and evaluation. Finally the following conclusions are drawn: the Sanjiazi gold deposit is a mesothermal deposit, and although it has undergone erosion to some extent, gold mineralization in its deep part is possibly promising.
