凸起凹陷构造控矿及找矿探讨——以泰安市区为例

Study on Structural Ore-control and Ore Exploration in Uplifts and Depressions ——Setting Tai'an District as an Example

摘要:

在泰安市所辖6个县市区范围内，分布着以铁、金等为主的金属矿产和以煤、石膏等为主的非金属矿产。两类矿产分别赋存于呈近SN向相间排列的5个凸起和5个凹陷构造中，铁、金等矿赋存于凸起，煤、石膏等矿赋存于凹陷。对凸起构造特征分析认为，南北方向相邻的凸起、凹陷构造本是一体，凹陷深部与凸起有相似的地质条件，相似类比理论为地质找矿工作提供了空间,应树立综合找矿和缺位找矿的思想，整合矿业权，实行整装统筹勘查。

Abstract:

Within the scope of six districts and counties in Tai'an city, there occurred metallic mineral resources, such as iron and gold, and non-metallic mineral resources, such as coal and gypsum. Two types of minerals resources occurred in five uplifts and five depressions alternately with the trend of SN. Iron, gold and other minerals occurred in the uplifts; while coal, gypsum and other minerals occurred in depressions. On the basis of analyzing structural characteristics of uplifts, it is regarded that uplifts and depressions with the trend of SN are integrated. The deep part of the depression has the similar geological conditions with the uplifts. Similar analogy theory will provide space for geological prospecting work. In two types of minerals and probably omissed minerals exploration, iron and gold deposit should be found in uplift, and coal, gypsum, oil exploration should be found in depressions. Comprehensive prospecting and exploration ideas should be established in order to integrate mining and co-ordinate the implementation of fully equipped exploration.
