通过对沙溪斑岩铜矿床的研究,以构造-岩浆活化成矿背景和四级控矿构造为依据,提出了构造岩石屏蔽、背形核部控矿定位的模式及其依据,并讨论构造活动对成矿元素化学行为的控制作用,着重分析了强矿化剂元素F与Cu含量的关系,提出了成矿元素垂向分带、水平分带和迁移富集的地球化学模式。运用此模式预测了沙溪矿床邻区一个相似的成矿远景区,初步证明了本文提出的构造控矿模式。
Based on the study of the Shaxi porphyry copper deposit, based on the tectono-magmatic activated mineralization background and the fourth grade ore control structure, the models and their basis for controlling the ore-bearing of the tectonic rocks and the dorsal nuclei are proposed and discussed Tectonic activities on the chemical behavior of the ore-forming elements. The relationship between element F and Cu content of the strong mineralizer is analyzed emphatically. Geochemical models of vertical zonation, horizontal zonation and migration and enrichment of ore-forming elements are proposed. Using this model to predict a similar metallogenic prospect in the adjacent area of Shaxi deposit, it proves the tectonic ore-controlling model proposed in this paper.
