基于三维地质建模的青海松树南沟金矿区找矿预测研究
Research on prospecting prediction of Songshunangou gold district in Qinghai province based on Three-dimensional geological modeling
摘要
Abstract
The Songshunangou gold district is located at the southern edge of the central part of the North Qilian orogenic belt.In response to the demand for finding minerals in the deep margin of this district,we estimate the resources of the ore body of its Western deposit and carry out the prediction of mineralization in the deep margin.Based on Surpac software and Leapfrog software,the geological database and 3D geological model of the mining area were established by combining display modeling and implicit modeling.The resource estimation of the ore body was carried out using a geostatistical method.Finally,the prospecting-information contents method was carried out using the finding information quantity method,which extracted the favorable ore-control factors of the deposit and established a comprehensive prediction model.The metal content of the Western deposit in the Songshunangou gold district is 19.59 t by the geostatistical method.Meanwhile,the comprehensive prediction model was used to delineate three prospecting targets,and the predicted potential metal content reached 2.85 t.The comprehensive metallogenic prediction of the Western deposit in the Songshunangou gold district enables the 3D quantitative prediction of potential mineral resources in the deep section.It provides suggestions and references for the next phase of deep-side prospecting and exploration for the Western deposit.关键词
