| 在国外开展地质找矿工作首先遇到的困难就是相关资料难以收集,遥感战略选区可以解决这一难题。利用遥感技术优势,不仅能克服地域、自然环境等方面的限制,而且可以快速地对区域地质背景及成矿条件等进行分析研究,从而为后续地质工作的开展提供基础资料。此次研究利用多光谱卫星遥感数据,在分析所收集的地质矿产资料基础上,对智利阿塔卡马区斑岩铜矿带开展遥感影像特征及成矿地质条件分析、矿化蚀变信息提取、成矿预测等研究,划分了3个成矿亚带,选取了3个战略选区,圈定了6处找矿靶区,并提出了进一步开展地质找矿工作的建议,取得了良好的应用效果。 |
| 英文摘要: |
| It is always difficult to collect relevant geologcial data when carrying out geological prospecting work in foreign countries, using remote sensing technology will solve this problem, it will not only overcome the liminations of regional and natural physical environmental, but also quickly extracts the relevant information of regional geological background and metallogenic conditionsetc, which guides the next stage exploration plan. In this case study, the characteristics of the remote sensing image, metallogenic geological conditions, extraction of mineralized alteration information and metallogenic prediction were carried out in the Atacama porphyry copper belt using multi-spectral satellite remote sensing data on the basis of analyzing geological and mineral deposit data collected,etc. The study has divided the copper belt into three sub metallogenic belt, selected three strategic target areas, delineated six prospecting targets. Finally the authors propose the exploration advices for further work, and achieved good exploration effect. |
