| 中文摘要: |
| 秘鲁（Peru）位于南美洲西海岸的安第斯成矿带北部，该成矿带是斑岩型铜矿蕴藏量最大和最集中的地区。秘鲁中南部大多分布已在开发的大型矿区和开发多年的老矿区，而滨海北部一带地质工作程度相对较低，因此本研究选择了秘鲁兰巴耶克省（Lambayeque Province）奇克拉约市（Chiclayo）东部地区为研究对象，运用ETM、ASTER等多光谱遥感影像提取矿化蚀变信息，通过野外调查验证，结合成矿地质条件及成矿预测分析，圈定找矿靶区2处，以期为后期该区域找矿工作提供一定参考。 |
| 英文摘要: |
| Peru is located in the north of the Andean metallogenic belt， western coast of South America， which has the largest and most concentrated porphyry copper deposits. In central and southern Peru， it is widely distributed that large mining areas and old mining areas which have been developed for many years， while the degree of geological work of the northern coastal area is relatively low. Therefore， this study chooses the eastern area of Chiclayo City in Lambayeque Province of Peru as the research object. Using ETM， ASTER and other multi-spectral remote sensing images to extract mineralization alteration information， through field investigation and verification， combined with metallogenic geological conditions and metallogenic prediction analysis， two ore prospecting target areas are delineated， in order to provide reference for the future prospecting work in this region. |
