东川铜矿已有四百多年的开采历史,过去的开采对象主要是裂隙型富矿。解放初期,由于认识的局限性,只注重大而贫的层状铜矿,忽视了小而富的裂隙矿体。后来的矿山地质工作基本沿用初期的概念,对裂隙型矿体未进行专门工作。近年来,我局广大矿山地质工作者,深入实际,系统调查,根据大量的第一性资料认为,东川铜矿不属于岩浆源的中温热液矿床,应为沉积变质矿床。随着矿床成因认识的突破,不仅在过去的无
Dongchuan copper mine has been more than 400 years of mining history, mining the main object of the past is fractured bonanza. In the early period of liberation, due to the limitation of understanding, only the large and poor stratiform copper deposits were emphasized, and the small and rich fractured ore bodies were neglected. Later, the basic geological work of mining follow the concept of the initial stage of the fractured ore body without special work. In recent years, a large number of mine geologists in our bureau have conducted thorough and systematic investigations. According to a large amount of first-rate data, Dongchuan Copper Mine is not a mesothermal hydrothermal deposit of magmatic origin and should be a sedimentary metamorphic deposit. With the breakthrough in the genesis of the deposit, not only in the past without
