Deposits Geological Characteristics And Ore Potential Analysis Of The Hulu Valley Gold Field In Shan County

Xiaoqinling, Xiong’ershan, Xiaoshan district is a major gold production in NenanProvince.In recent years,with the deepening of geological work,prospecting has madesignificant breakthroughs in Xiaoshan district.It is only inferior to Xiaoqinling, Xiong’Ershan the non-ferrous metal and the noble metallogenic mineralizes.The hulu valley goldore area is the structure to flatten the low mountainous area, locates the geostructure positionfor the North China platform south the reason and north the Qinling orogenic zoneengagement intermediate belt.It is situated at the Henan Province Sanmenxia south, is apartfrom Shan county county seat Nandong45km, the transportation convenience, the minerals isrich, colored, precious metal mineralization centralism, already gradually became the focalpoint area which the people focused attention on.The mining area is located the model in the deterioration nucleus mixed crag, his/herkern is composed by the archaean group too China group crystalline basement,, the boundaryfor opens to the fault, the cap rock by the ancient proterozoic group stratum is composed.Themineral lode occurs in the north-west trending faulted structure, the length reaches tens ofmeters to several kilometers, ore body thickness is on the average of0.6meter, but thepersonal status is rich is its characteristic. Gold mineralization and widespread developmentof silicification, pyrite alteration and so closely related. Regional development ArcheanTaihua Group formations, etamorphic medium. Zone of tectonic activity with multiplefeatures, the distribution of multiple gold polymetallic deposits (points). Mineralization in thearea has excellent condition, great exploration potential.This article considered that the type of gold deposit mainly belong to fractured alterationzone,which occurred in the metamorphic rock of Taihua Group through the analysis of oredeposit geology,and ore-controlling conditions of Huluyu gold deposit. Detachment fault andfault belts especially NW-trending fault belts were main ore-controlling structure. In addition,it analyzed three important mining area, which was good prospecting perspective of Huluyugold deposit.Through to formerly worked the achievement acquisition of information, unifiedthe mining area geological investigation, the ore appraisal, the rock mass host quantityelement and the trace element analysis and so on the microexamination, investigatedthoroughly the crag ore the structure structure, the mineral composition, summarized the oreforming element depth portion to concentrate the rule, the mineralization concentrates therule; Forecast the depth portion prospecting dvantageous spot, has simultaneously pointed outthis mining area next step prospecting direction.
