Abstract:
Shijing gold-silver deposit,which is lied in Jurassic volcanic and pyroclastic rocks,is composited of two gold and silver mineralization belts,fourteen mine(change) bodies,and is obviously controlled by the fracture structure.The function of enrichment of main mineralization is related with volcanic hydrothermal activity.In middle-low temperature volcanic hydrothermal in the environment of the Mesozoic,gold-silver ore-forming hydrothermal is enriched firstly by heat power and boiling function and then sediment and enrichment because of cooling, reduced pressure.Ore-forming materials mainly comes from the surrounding rock,ore genetic types is low epithermal volcanic hydrothermal,industrial types is quartz vein-broken altered rock.It has good prospecting marks of strata,vein rocks,structure,mineralized alteration,geochemical.It is favorable for regional metallogenic conditions and prospecting potential.
Key words: Gold-Sliver deposit, Geological features, Genesis, Prospecting indicator, Jilin Province
