摘要
矿床模拟法是成矿地质环境模拟、类比方法,可据此估计在特定地质成矿环境中的某矿产资源潜力.本文探索利用矿床模拟法对辽宁清原太古宙地体中的金矿床进行综合预测.原始数据取自1∶5万区域地质调查资料,共观测地层、构造、岩浆岩、接触带和化探资料等9个逻辑变量.预测结果显示了几个新的有利金矿靶区,有必要进行重点勘探工作.
The deposit modeling method is a method of metallogenic environment modeling and analogy. The assessment of mineral resource potential using the deposit modeling method is made by predicting the existence of generalized deposit models in recognized favorable geological environment within an area of interest. In this paper, we try to use deposit modeling method to predict gold resources in Qingyuan district, Liaoning. The data are completely based on the regional geological survey in the scale of 1: 50000. As the original data for calculation 9 variables are selected from the stratigraphy, structure, magmatic rocks and their contact zones, and pedogeochemical prospecting. The results of prediction point out several new target areas where gold deposits have not been found and it is necessary to emphasize exploration for gold deposit in these areas.
