摘要
结合遥感技术的现状、发展趋势和资源环境应用需求 ,从遥感地质应用出发 ,提出多源遥感数据分层识别集成、基于岩矿识别技术体系集成和基于岩矿识别谱系集成的基本思路与框架 ,强调矿物或矿物集合体在遥感地质分类与识别中的重要性 ,初步建立矿物遥感地质分析模型 ,分析集成与模型在蚀变与矿化信息提取。
The idea of synthetic integration for extracting and analyzing the geological information is put forward and discussed. Three integration modes, of hierarchical identification using various scales of remote sensing, of discrimination methods and techniques for minerals and rocks, and of spectral identification tree based on spectral frature of minerals and rocks, are primarily established. Of all, minerals or mineral assemblages discrimination are emphasized. Two combination analysis models for geological application, which are based on the single mineral identification and on the mineral assemblage identification using remote sensing, are established. It is most potential for extracting information of alteration and mineralization, and analyzing the geological environment. Both the gold deposit of Chicheng-chongli in Hebei Province and Cuprite district are as test areas, which used technique combination of both the synthetic integration and combination analysis models for geological application. The potassic altered mineral assemblage, which are strongly related to the genetic source for gold deposit, are extracted from Chicheng-chongli area in Hebei Province. The seven Mineralization and Alteration spots are extracted and confirmed. The geological genetic are analyzed effectively according to the intergrowth minerals which are discriminated using AVIRIS data at Cuprite district in U.S.A..
