Metallogenic Conditions And Prospecting Prediction Of Copper And Gold Deposit For Fenghuangshan Area Of Hanyin County,Shaanxi Province

As the national economy continues to grow,the demand for mineral resources is increasing day by day,and the proven resource reserves at this stage can no longer meet the needs of social development.Shaanxi Province,as an important producing area of mineral resources,has increasingly prominent contradictions between the supply and demand of mineral resources.It is urgent to realize breakthroughs in prospecting for existing mineral resources and find new mineral resources to alleviate the contradiction between supply and demand of mineral resources and promote the sustainable development of mining.The implementation of geophysical and chemical prospecting work in the mineral blank area,the study of mineralization conditions,and the development of prospecting predictions can achieve breakthrough progress in mineral prospecting and ore prospecting in Shaanxi Province and provide an important basis for subsequent prospecting work.This paper is based on the "Pre-investigation of Gold and Silver Polymetallic Ore in Fenghuangshan Area,Hanyin County,Shaanxi Province",and on the basis of fully absorbing and digesting previous data,combined with the results in geological and geochemical prospecting of the project,analyzed the geological and geochemical characteristics of the mining points,using the comprehensive geological analysis method.Based on the above work,the analysis of the working area's metallogenic conditions and the study of prospecting predictions are carried out.Through research,the main progress made in this paper is as follows:1.Through the study on the anomaly of sediments in the water system on a map of1:25000,23 multi-element anomalous areas have been delineated.Study the relationship between anomalies and geological background,and select 8 of them as key anomalies for anomaly verification.2.Through the inspection of key anomalies,it was discovered that three ore sites,including the Luyugou copper-molybdenum mine.After research,the geological characteristics of each ore site,such as ore body characteristics,ore-controlling conditions and ore-controlling factors,were basically determined.Submitted the Luyugou copper-molybdenum mine deposit.3.Combining some predecessors' data,comprehensively integrating the geological characteristics of the mining sites in the area,and studying the metallogenic conditions of the working area,it is believed that the copper and gold deposits in the Fenghuangshan area have good metallogenic conditions.The area is considered to be a favorable area for searching for copper-molybdenum deposits of "magma-hydrothermal type(related to porphyry type)" and "tectonic altered rock type" gold(silver)deposits.4.Combining the regional mineralization conditions and mineral resources,analyze and study the geological and geochemical characteristics of the mining points in the work area,and carry out prospecting predictions.Five prospecting prediction targets such as Luyugou and Wanjiapa are selected in the research area.And determined the target mineral species in the prospecting target area.
