本文在野外地质矿产调查的基础上,通过收集菲律宾内格罗斯岛西部地区地质矿产资料,分析该区铜、金矿的区域地质背景、成矿地质条件及成矿控制因素。结果表明,该区斑岩型铜矿和热液型金矿主要与内格罗斯岛岛弧岩浆岩带有关,受区域断裂构造破碎带、闪长岩和白垩系火山碎屑岩层控制,在类似部位或附近是寻找铜、金矿的有利地段。这对今后进一步寻找斑岩型铜矿、热液型金矿具有一定参考。
Based on the investigation of geology and mineral resources in the field, the paper collected the geologic and mineral data of the western Negros Island in the Philippines and analyzed the regional geological background, metallogenetic geological conditions and metallogenetic control factors of the copper and gold deposits in the area. The results show that the porphyry copper deposits and hydrothermal gold deposits in this area are mainly related to the arc magmatic belt of Negros Island and are controlled by regional faulted structural fracs, diorites and Cretaceous pyroclastic rocks. Parts or nearby are looking for favorable locations for copper and gold mines. This is a reference for further looking for porphyry copper deposits and hydrothermal gold deposits in the future.
