Abstract:

1∶50 000 soil survey was conducted in the Xiegou-Hongliuqiujing Area and a total of 5 625 samples were collected,with sampling sizes from 4 mesh to 20 mesh.Through sample processing analysis and geochemical parameter statistics,the geochemical characteristics of ore-forming elements were studied.A total of 467 single-element anomalies,3 types of combined anomalies,and 17 comprehensive anomalies were identified.Based on the anomaly veri-fication and evaluation,the comprehensive anomalies were classified and sorted.Based on the above,combined with the regional geological background and distribution of mineral resources,the research area has been pided into 5 prospecting prospect  areas mainly  composed of Au,Pb,Zn,W,and Mo,and their ore-forming potential has been preliminarily evaluated.It is believed that there are prospecting potentials for porphyry type molybdenum deposits,altered rock type gold deposits,and volcanic hydrothermal type gold deposits.
