GEOLOGY AND ORE-FORMING FLUID TYPES OF THE LINXIANG GOLD DEPOSIT, XUNYONG, SHANXI |
| |
| Abstract: | The Linxiang gold ore deposit is found in the Palaeozoic Devonican strata. The gold ore-bodies occur in carbonate, fine-sandy phyllite and phyllite, and the major ore-bearing wall rocks are confined to the EW ore-control fault.Pyrite, limonite, pyrrhotite, chalcopyrite and quartz are all the major carrier minerals of gold.The second and the third ore-forming stages are majormineralization stages. The stable isotope and ore-forming fluid characteristics suggest that the metallogenic substance comes mainly from orogenic belt strata,and the deposit is a shallow-seated, medium-low temperature, leaching, syngenetic gold deposit which was formed in sedimentary rock in the Yanshan epoch. |
