摘要
The researches on the metallogenic geological settings of the Jianquanzi gold deposit and Wenyu gold deposit show that they both have geological characteristics of orogenic hydrothermal gold deposits.On this basis,the characteristics of fluid inclusions as well as hydrogen and oxygen isotope compositions are analyzed and compared.It is found that the ore-forming fluids are characterized by medium temperature,low salinity and rich CO2,which accords with the characteristics of the fluid inclusions at typical orogenic gold deposits.The project points out hydrogen and oxygen isotope compositions data are mainly located in the mixure zone of magmatic water and metamorphic water,while tending to drift towards precipitate water.From the above analysis,it is concluded that the Jianquanzi gold deposit and Wenyu gold deposit are greatly similar in the metallogenic mechanism.And the metallogenic mechanism characteristics of the Jianquanzi gold deposit are discussed further in detail.
