| 摘 要： | 智利斑岩型铜矿闻名全球,世界上最大的丘基卡马塔和特尼恩特斑岩型铜矿就产于此地,主要分布在圣地亚哥-依基克一带,是地震-火山作用和侵入作用特别强烈的地区,成矿时代为拉拉米期(早白垩世—古近纪).通过对智利斑岩型铜矿区域地质特征和3个典型的斑岩型铜矿床成矿地质条件及矿床地质特征分析,得出智利斑岩型铜矿成矿与多期次岩浆活动密切相关,呈南北纵向成带展布、成群出现,成矿时代新、埋藏浅、储量大.Lowell-Guilbert的斑岩铜矿成矿模式和Hollister的"闪长岩模式"对智利斑岩型铜矿的勘查起了重要的指导作用.

| Abstract: | Chile is well known for its porphyry copper deposits in the world, with the world＇s largest Chuquicamota and El Teniente deposits of such type, distributed mainly in San Diego-Iquique region, where earthquake, volcanism and intrusion is seriously intensive. The metallogenic epoch is from Early Cretaceous to Paleogene. With study on the regional geology of Chile porphyry copper deposits, as well as metallogenic conditions and geological characteristics of three typical deposits, it is found that the mineralization of Chile porphyry copper deposits is closely related with multi-stage magmatism, distributed in north-south-trending belts and occurring in groups, with new metallogenic epoch, shallow bury and large reserves. The porphyry copper metallogenic model by Lowell-Guilbert and the diorite model by Hollister play important roles in the exploration of Chile porphyry copper deposits. |
