摘　　要：矿体成因类型分析对于研究成矿地质条件、成矿规律尤其是对地质找矿工作意义重大。本文针对钻探工程揭露到的深部矿体,通过与空间位置关系的比较确定了浅部矿体与深部矿体之间的关系。通过分析深部矿体与围岩的接触关系、不同矿石类型的分布特征以及矿石结构构造,阐述了该深部矿体为深部熔离-贯人型矿体,与浅部矿体的成因类型不同,为今后在Ⅲ矿区主矿体深部开展地质找矿工作提供了理论依据。It is great significance that the study of ore-body genetic types for the metallogenic geological conditions and metallo-genic laws,especially the geological prospecting work.In this paper,the relationship between the shallow ore-body and the deep ore-body is determined through the comparison with the spatial position of the deep ore-body exposed by the dilling project.By analyzing the contact relationship between the deep ore-body and the surrounding rock,the distribution characteristics of different ore types,the structure and construction of ore,it is stated that the deep ore-body is a dee melting-penetrating ore-body,which is diferent from the genesis of the shallow ore-body.It provides a theoretical basis for the future deeply geological prospecting work in the main ore body of the Ⅲ mining area.
