位于康滇地轴中段、川南滇中中生代断陷盆地中的砂岩铜矿,在五十年代后期,已引起广泛注意.它具有矿点分布众广,品位较富,易采易选等特点,但地表出露面积小,远离岩浆岩体,在岩浆热液成矿论盛行的当时,被认为是一种规模不大的远离岩浆源的中低温热液矿床而没有给予适当的重视.六十年代,随着同生成矿理论的兴起,勘探实践的深入,滇中砂岩铜矿的成因问题和矿体赋存规律都有了进一步的了解.采用同生成矿理论总结的浅紫交互带、矿物分带和水下地形(即众所周知的“三板斧”)成矿规律,相继在滇中探明了十余个大中小型
Sandstone copper deposits, located in the middle of the Kang-Dian axis and in the Mesozoic-Cenozoic rift basins in the southern Sichuan and Yunnan provinces, have attracted wide attention in the late 1950s and have the characteristics of widespread ore points, rich taste, easy selection and easy selection, etc. However, At the time of the prevalence of magmatic hydrothermal mineralization, it was considered as a small-scale, intermediate-low-temperature hydrothermal deposit far away from magmatic sources without proper attention due to its small surface area and distance from magmatic rocks. , With the rise of synoptic ore-forming theory, the exploration of practice, the origin of the sandstone copper deposit in central Yunnan and the rules of orebodies have been further understood.Using synchronic mineralization theory, Belt and underwater terrain (that is, the well-known “three axes ”) mineralization law, have been proven in Yunnan in more than ten large, medium and small
