摘要
印度尼西亚矿产资源丰富,主要矿产包括镍、锡、铜、铝、金、铁、银、煤等,矿业是其重要的经济支柱产业,也是外国投资的传统热点行业。本文在系统梳理主要矿产典型矿田/矿床类型、规模、地层岩性、构造-岩浆作用和成矿年龄等研究成果基础上,总结刻画了与主要矿产成矿密切相关的9个三级成矿带及其成矿特征,识别出代表性成矿带5个主要成矿期次,即中二叠世—晚三叠世(265~220 Ma)、白垩纪—渐新世(145~30 Ma)、中新世(22~7 Ma)、上新世(4 Ma)、更新世—全新世(1 Ma~至今)。
As rich in mineral resources,mining industry in Indonesia was an important economic sector and a traditional hot topic industry for foreign investment.The main minerals resources include nickel,tin,copper,aluminum,gold,iron,silver,coal,etc.Based on previous research,the relationships between main mineralization processes and the Indosinian-Yanshan and Himalayan Tectonic Event were summarized,and 7 second-order tectonic units and 12 third-order tectonic units were divided.Based on summarizing the typical type and scale of ore fields and deposits,stratigraphic lithology,tectonic-magmatism,and metallogenic age,9 tertiary mineralization belts were divided,in which the mineralization characteristics were summarized and 5 representative mineralization epochs were identified.These five metallogenic epochs are respectively Middle Permian-Late Triassic(265 to 220 Ma),Cretaceous-Oligocene(145 to 30 Ma),Miocene(22 to 7 Ma),Pliocene(4 Ma)and Pleistocene-Holocene(1 Ma to now).
