西部某地区地球化学特征及找矿预测

Geochemical Characteristics and Prospecting Prediction of Tianshuihai Area in Xinjiang

对西部某地区的地质背景及区域地球化学特征进行分析,在此基础上进行了1∶5万化探普查工作,对区内地质体内元素分布特征、元素共生组合特征等进行分析的同时对化探异常进行圈定并评述。通过对异常区进行野外地质验证,认为研究区晚三叠统克勒清河组和早侏罗统巴工布兰莎组为主要含矿地层。通过对元素地球化学参数特征、元素共生组合特征、主要地质体元素分布特征等方面对研究区地球化学特征及其分布规律进行研究。在对研究区异常评价与解释推断基础上进行了资源潜力评价,划定找矿远景区2处,经综合研究认为,此次工作效果显著,成果可靠,并为该区今后找矿提供了方向。

The geological background and regional and geochemical characteristics of the study area were analyzed.Based on this,a 1∶50000 geochemical survey was carried out,and the geochemical anomalies were delineated and reviewed while the element distribution characteristics and element symbiotic combination characteristics were analyzed in the geological body.Through field geological verification of the anomaly area,it is considered that the Late Triassic Keleqinhe Formation and Early Jurassic Bagong Bransha Formation are the main ore-bearing strata in the study area.The geochemical characteristics and distribution law of the study area were studied from the aspects of element geochemical parameters,element symbiotic association and element distribution of main geological body.On the basis of the anomaly evaluation and interpretation,the resource potential evaluation is carried out,and two prospecting areas are delimited.The comprehensive study shows that the work is effective and reliable,and provides a direction for the future prospecting in this area.
