鹤庆锰矿产出于晚三叠世诺利期剧烈下陷的一个台沟环境。力学成因上 ,该台沟盆地属于走滑拉张型盆地。它的生成与西缘台褶带卡尼 -诺利中期区域性南北向深大断裂带的右行走滑拉张活动有直接的关系。稀土和碳、氧同位素资料表明 ,成矿经由以玄武岩浆活动为代表的地热系统对盆地基底矿源层中锰质的萃取、生物吸收以热水喷流形式进入盆地的矿质而成矿的过程。总结出区域性深大断裂、玄武岩浆活动、矿源层三者为扬子地块西缘卡尼 -诺利成锰期的控制因素
Heqing Manganese ore production in the late Triassic Nori period of a severe subsidence of Taiwan and Taiwan environment. Due to mechanical reasons, the Taitou Basin belongs to the strike-slip extensional basin. Its formation is directly related to the right-lateral sliding sliding activity of the north-south trending deep fault zone in the mid-stage of the Canili-Noli in the western margin of the margin. Rare earths and carbon and oxygen isotope data show that mineralization process through the geothermal system represented by basalt magma activities into the mineralization of the basin by the hot water jet into the basement source bed of manganese ore. It is concluded that the regional deep faults, basaltic magmatism and the source rocks are the controlling factors of the Karni-Norils into manganese in the western margin of the Yangtze block
