Characteristics of Structure and Control of Ore in the Sanguanmiao Gold Deposit, Luoning County, Henan Province

Sanguanmiao gold deposit located in the south of porphyritic granite near the contact zone of the Taihua group and Xiong'er Group.Detachment fault zones and alteration zones of interlayer slip fault developed in the mining area.The rock structure in the fracture zone of alteration containing gold is main ore-bearing rock.The form of ore bodies is mainly stable layered.Gold minerals is mainly Silver Gold mine.Carrier minerals of gold are pyrite,quartz,and galena.Wall rock alteration is silicification,pyrite,galena,chloritization,sericitization,and so on.Mineralization type is silicified altered rock type gold mine.In the multi-stage intense tectonic-magmatism,regional metamorphism and migmatization processes,the gold element can form ore body along the alteration zone of interlayer slip faults.
