前言我国某地区砂岩铜矿床曾由地质、冶金部门的地质队、昆明工学院、地质科学研究院等单位进行过研究,对矿床所作的规律性总结,在地质勘探工作中起了积极的作用,但在矿床成因问题上仍存在分歧意见。主要观点有二:其一,认为矿床为同生沉积期产物,环境属古代湖泊,矿床及与之密切相关的岩石红—灰色调的形成受湖泊微地貌控制;其二, Preface The sandstone copper deposit in a certain area of ​​our country has been studied by the geological team of geology and metallurgy department, Kunming Institute of Technology, Institute of Geological Sciences and other units. The regular summary of the deposit has played an active role in the geological exploration work , But there are still differences on the cause of the deposit. The main points are twofold: First, it is considered that the deposit is the product of the same depositional period, the environment is an ancient lake, the deposit and the closely related rock red-gray tone are controlled by the lake micro-topography;
