摘要
斑岩铜矿的成矿作用与成矿能量的消耗是相并而行的。从成矿元素由分散到集聚过程的热力学体系变化 ,估算了形成德兴斑岩铜矿田的成矿能量 ;探讨了成矿能量的来源及其与成矿斑岩的关系 :认为斑岩并非矿田成矿能量的唯一来源 ,部分来自地球深部的内热产生的局部性对流热。
Mineralization of a porphyry copper deposit goes parallel with the consumption of mineralization energy. Based on the variation in thermodynamic system in relation with the process of ore-forming elements from a dispersion to an accumulation state, the author has estimated the mineralization energy consumed during the formation of the Dexing porphyry copper ore field, and discussed the source of mineralization energy and its relation with the ore-related porphyry, suggesting that the mineralization energy was derived not only from the porphyry, but also partially from the local convection heat produced from internal heat of the Earth at depth.
