| 中文摘要: |
| 云南东川铜矿是我国最重要的铜矿田之一，具有悠久的勘查开发历史和丰富的科研成果，其矿床成因一直以来是学术界争论的话题。本文在前人研究基础之上，结合近年来实地工作成果，认为东川铜矿具有赤铁矿 -辉铜矿-斑铜矿 -黄铜矿的矿物组合和一定的分带特征，多层位成矿特征显著，与中非铜矿带SSC矿床具有高度可比性，其含矿建造系统和高角度断层供给系统为主要控矿要素，并可作为找矿勘查的直接依据。研究表明东川铜矿仍具有较大找矿前景，多层位找矿思路是该区域实现找矿突破的重点。 |
| 英文摘要: |
| Dongchuan Copper Mine in Yunnan Province is one of the most important copper .elds in China, with a long history of exploration and development and rich scientific research achievements. The genesis of Dongchuan Copper Deposit has always been a controversial topic in the academic circle. Based on previous studies and combined with the results of field work in recent years, this paper holds that Dongchuan Copper Deposit has the mineral assemblage of hematite-chalcocite-bornite-chalcopyrite and certain zoning characteristics. The multi-level metallogenic characteristics are signi.cant. It is highly comparable with the SSC deposit in the Central African copper belt. The ore bearing formation system and high angle fault supply system are the main ore controlling factors, and its can be used as the direct basis for ore prospecting. The research shows that Dongchuan Copper Mine still has a great prospecting prospect, and the multi-layer prospecting idea is the key point to realize the prospecting breakthrough in this area. |
