摘要
矿床地质地球化学和矿床矿物学的研究结果表明,珊瑚钨锡矿床具有多矿化阶段的水平侧向正常分带特征。无论从矿脉的矿物共生组合、矿物标型特征,或是近脉的蚀变作用,它们之间都存在某些相似、继承的演化关系。自东向西,随距矿化中心距离的增大,成矿过程中岩浆热液成矿作用逐渐减弱,而热液改造成矿作用越趋强烈。矿床西侧首次发现的金矿化,正是这种热液改造成矿作用的显示。
The studies of geologic-geochemistry and mineralogy in the Shanhu tungsten-tin deposit show that the depoist has the character horizontally lateral normal zoning caused by the mineralization of various stages and controlled by the hidden granite. No matter what the mineral paragenetie association and typomorphic character, or the atteration near the veins, there exist some genetically developing and evolutionary relationships between the veins.
From the east to the west, with the increase of the distance from the mineralizing centre, the magma-hydrothermal mineralization gradually weakens and the hydrothermal reconstruction mineralization is more intensive. The gold mineralization has been discovered for the first time on the west side of this mine, and that is just the demonstration of the reconstruction process.
