摘　　要：针对南美洲沉积型铜矿类型和成矿带划分,基于Google Earth遥感影像,对典型矿床进行遥感地质解译,建立了不同沉积铜矿类型的遥感地质解译标志。基于Landsat--ETM遥感影像,依据沉积型铜矿分布、控矿地质条件和遥感影像特征,将南美洲沉积型铜矿划分为滨太平洋一级成矿带和北部二叠纪、中部古近纪和南部白垩纪等3个次一级成矿带。Aiming at the types of sediment-hosted copper deposits and its metallogenic belt division in South America,the typical sediment-hosted copper deposits were interpreted based on the Google Earth remote sensing image,and the interpreted indicates of the different types sediment-hosted copper deposits have been established.Based on the Landsat-ETM remote sensing image,the Peri-Pacific first level metallogenic belt and three second level metallogenic belts including northern Permian metallogenic belts,central Paleogene metallogenic belts and southern Cretaceous metallogenic belts,were divided in South America according to the distribution and geological conditions as well as the remote sensing image characteristics.
