HG 铜矿位于智利第四大区科金博东南约50 km，是一个以铜为主的中型铜（银金）矿，为中安第斯成矿带的一部分。结合 HG 铜矿区域地质条件，运用区域成矿学和现代成矿理论，通过矿床地质学、成矿构造学和矿物岩石学等方面的研究，阐明 HG 铜矿的地质特征和成矿规律，进行成矿预测，对矿区找矿工作具有重要指导意义。研究表明，上白垩统（KIag）花岗闪长岩、花岗闪长斑岩、花岗岩、正长岩等组成的杂岩体为矿区主要赋矿岩层和成矿母岩。区内岩浆活动，尤其是后期酸性岩体的侵入使得成矿母岩中成矿物质进一步交代和富集。结合矿区地质、物化探资料，指出斑岩型和构造破碎型成矿远景区。

HG copper deposit is located in the southeast of Coquimbo in Chile, which is a medium-size copper (Silver, gold) ore polymetallic deposit and mainly composed by copper ore. It is a part of the Andean metallogenic belt. Integrating with the geological conditions of HG mine, based on the metallogenic theories related to the regional metallogeny and modern metallogeny, this paper has clarified the geological features and the metallogenic regularities of HG copper deposit, and the metallogenic prediction was forecasted through the comprehensive research on the mineral petrology, metallotectonic and mineral deposit, which is significant for ore-prospecting practice. The researches show that Upper Cretaceous (KIag) complex is the hosting rock and mother rock, and it is including granodiorite, grandiorite-porphyry, granite and syenite. The magmatic movement in this area is the main causes for the further replacement and enrichment of metallogenic material, especially the acid rock irruption. Based on geological, geophysical and geochemical data, this paper indicates porphyry-type and structure fracture mineralization prospecting area.
