中文摘要: 河南栾川县白土铅矿床位于华北地台南缘、NWW向的马超营大断裂上,结晶基底为太华群构成,中元古代熊耳群安山岩不整合于太华群之上,中元古代晚期沉积了官道口群浅海相碳酸盐岩建造,矿体产于碳酸盐岩中的次级断裂带,呈脉状、似层状分布。对矿床的成因类型进行了总结:裂谷环境经复杂的构造演化形成马超营断裂带及该区近东西向的浅海相白云岩,燕山期区域挤压环境下,热液沿基底断裂及裂隙通道上侵并白云岩中的铅活化、迁移形成含矿热液,在有利位置富集成矿,总体上属于受碳酸盐岩制约的陆相火山岩型铅矿床。
Abstract:The Baitu lead deposit in Luanchuan County, Henan Province is located on the southern margin of the North China Platform and the Ma Chaoying fault in the NWW direction. The crystalline basement is composed of the Taihua Group. The Middle Proterozoic Xiong"er Group and Anshan Rock are not integrated on the Taihua Group. In the late stage, the shallow sea-phase carbonate rock of the Guandaokou Group was deposited. The ore body is produced in the secondary fault zone of the carbonate rock, which is vein-like and layer-like. The genetic types of the deposits are summarized: the complex tectonic evolution of the rift valleys forms the Ma Chaoying fault zone and the shallow east-west shallow dolomite in the area, and the hydrothermal fluid along the basement fault and fissure channel in the Yanshanian regional extrusion environment Lead activation and migration in the upwelling and dolomite form ore-bearing hydrothermal fluids, which are rich in minerals at favorable locations, and are generally continental volcanic-type lead deposits restricted by carbonate rocks.
