摘要
利用遥感技术对北美洲新生代地层的遥感地质特征进行研究,总结和分析不同区域新生代地层(第三系、第四系)的影像特征及其分布和变化,分别建立遥感解译标志。在解剖佛罗里达地区沉积型磷矿床的基础上,分析其控矿要素的遥感影像特征,为今后开展境外相似地区地质调查及找寻同类矿床提供遥感技术支持,对减少境外矿产投资的盲目性具有一定的指导意义。
Geological characteristics of Cenozoic strata in North America have been studied by using remote sensing technology,with the image features,distribution and changes of Cenozoic strata(Tertiary and Quaternary)in different regions being summarized and analyzed,and their remote sensing interpretation markers being established,respectively.Based on analysis of sedimentary phosphate deposits in Florida,remote sensing image features of ore-controlling elements have been analyzed,thus providing a reference for carrying out geological survey and searching for similar ore deposits overseas in similar areas in the future,and reducing the blindness in transnational mineral investment.
