摘要
在斜沟—红柳丘井地区开展1∶50 000土壤测量,采集样品5 625件,粒度为4目至20目。通过样品加工分析和地球化学参数统计,对成矿元素地球化学特征进行研究,圈定单元素异常467处、组合异常3类、综合异常17处。根据异常查证评价情况对综合异常进行了分类及排序。在此基础上,结合区域地质背景、矿产资源分布情况,划分了以Au、Pb、Zn、W、Mo为主的找矿远景区5处,初步评价了其成矿潜力,指出具有找矿潜力的矿床类型为斑岩型钼矿床、蚀变岩型金矿床、火山热液型金矿床。
1∶50000 soil survey was conducted in the Xiegou-Hongliuqiujing Area and a total of 5625 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 divided 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.
