摘要
南岭地区是世界著名的钨矿床集中区,国内外许多学者进行了大量的工作。本文通过对南岭地区钨矿形成经历深源物质喷溢、风化剥蚀、沉积、地层重熔成岩、花岗岩多次演化、岩浆热液析出、成矿母岩碱质交代、酸淋滤萃取、热液运移、聚集沉淀成矿等多期多阶段成矿作用探讨研究,认识到碱质交代的成矿母岩、流体的钙质丰富时,一般形成白钨为主的矿床;当碱质交代的成矿母岩贫钙时,一般形成黑钨矿床。
The Nanling area is one of famous tungsten concentrated areas in the world. Many domestic and foreign scholars have made researches in the area. Through multi-times multi-stages mineralization discussion of tungsten formation by the deep source effusion, weathering denudation sedimentation, the strata remehing, the granite muhievolution, the magma hydrothermal eruption, mother rock replaced by alkali ,the sour leaching extract,the hydrothermal migration, accumulation the precipitation mineralization and so on, the authors proposed when the mineralization mother rock rich in calcium was replaced by the alkali, the white tungsten was formed;when mineralization mother rock of poor calcium was replaced by alkali .the black tungsten was formed.
