Study on Geological Characteristics and Prospecting Direction of No.3 Vein in Gutaishan Gold-antimony Deposit,Hunan Province
The Gutaishan gold-antimony deposit is an important medium-sized gold-antimony depos-it in central Hunan,which belongs to the type of broken zone related to magmatic activity.In order to clarify the geological characteristics and prospecting direction of No.3 gold-antimony vein,based on the analysis of mine geological data,the research work of tunnel survey,drilling verification,rock and ore testing and geo-chemistry has been carried out.The results show that the Jiangkou Formation is a source layer,and the ore-forming elements in the source layer are activated by regional metamorphism,magmatic hydrothermal activi-ty and tectonic movement,which enter the ore-forming fluid and migrate with it,and then enrich the ore-forming in the suitable ore-bearing structure.The vein is obviously zoned in the vertical direction,with a stepped side,and the side Angle is about 70°.Two prospecting targets have been predicted,and four bore-holes have been drilled in No.1 prospecting target,and industrial ore bodies have been seen in all of them,indicating that the deep mining area has a good prospecting prospect.
