南岭中段锡资源总量预测

The prediction of total tin resources in the central part of Nanling region

南岭中段地区成矿地质条件优越,是中国主要的锡矿产区,近年来的地质找矿又取得了新的突破。笔者从成矿地质背景分析、矿床类型划分入手,在成矿地质条件优越、锡矿资源丰富、矿床类型复杂及工作程度较高的区域,运用"三步式"资源评价方法,结合中国地质类比法及综合地质法等多源地学综合预测理论,采用MRAS资源量评价系统对南岭锡资源潜力进行预测。

Nanling region has favorable geological conditions for mineralization and hence serves as the main tin producing area in China. In recent years new breakthrough has been made in geological prospecting. Beginning with an analysis of ore-forming geological background and the classification of ore deposit types, the authors chose some study areas where ore-forming geological conditions are favorable, tin resource are abundant, ore deposit types are complex and working extent is relatively high. Adopting the ＂three step＂ resource estimation method in combination with other multi-source geological synthetic prediction means such as the Chinese geological analogy method and the integrative geological method, the authors utilized the resources extent evaluation system to predict the tin resource potential.
