康滇地轴北段(以下简称“北段”)东缘系指北起雅安,经雷波、宁南至云南会泽,南北长450余公里的地带.它是我国著名铅锌矿产地.长期以来,对此带铅锌矿床认为是与岩浆作用有关的远成热液矿床,尽管在找矿实践中遇到许多与此观点相矛盾的地质现象,仍因受岩浆热液成矿论的束缚而没有提出更多异议. “北段”东缘铅锌矿带位于川滇黔鄂台拗与“北段”接壤地带.该带自晚震旦世至早古生代末发生了较强烈拗陷,沉积了厚大的碳酸盐岩和碎屑岩建造.在碳酸盐岩建造
The northern margin of Kangdian axis (hereinafter referred to as the “northern section”) refers to the eastern edge of Ya’an, north of Leibo, south of Yunnan to Huize, north-south length of 450 km. It is China’s famous lead-zinc production. Since this zone, the lead-zinc deposit is considered as a far-field hydrothermal deposit related to magmatism. Although many geological phenomena that contradict this view have been encountered in ore-prospecting practice, due to the constraint of the magmatic hydrothermal mineralization theory While no objections were raised.The Pb-Zn ore belt in the eastern margin of “North Section” is located in the border area between E’tai’ao’’O’tai’ao and ’North Section’ in Sichuan, Yunnan, Guizhou and Guizhou Provinces with strong depressions occurring from the Late Sinian to the Early Paleozoic, Built with thick carbonate and clastic rocks. Built in carbonate rocks
