摘要
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 field geological and mineral survey,and geological data collected from the western Negros,Philippines,it is analyzed the regional geological backgrounds,geological condition of mineralization and mineralization controlling factors of the copper and gold deposits in this area.The result shows that the porphyry copper deposits and hydrothermal gold deposits are related to Negros arc magmatic belt,mainly controlled by regional faulted structural fracture zones,diorites and Cretaceous volcanic clastic rocks,and the similar positions or nearby areas are favorable locations for prospecting copper-gold deposits,which having important significance for further prospecting for porphyry copper deposits and hydrothermal gold deposits in the future.
