【摘要】 兰坪盆地成矿带是我国最重要的有色金属成矿带是全国固体矿产资源十六个重点成矿区带之一,Cu, Pb, Zn, Ag储量丰富,本文在充分搜集分析云南兰坪盆地区域以往地、物、化、遥及矿产勘查资料的基础上,综合运用地球物理、地球化学、遥感等的理论和方法,全面系统地研究了兰坪盆地各种有利成矿条件,并在此基础上进行了成矿预测。1、通过兰坪盆地的遥感图象处理、信息提取和地质解译及野外调研,作者对兰坪盆地断裂构造以及构造运动进行了解译。2、对区域1:20万地球化学水系沉积物进行了处理和成图,圈定了区域若干个具有成矿潜力的地球化学异常。3、对兰坪盆地区域所处的三江地带矿床分布特征、矿化特征、成矿规律进行了全面总结和分析。4、多元信息综合分析充分发挥了各种技术和理论的优势,集中反映了所有能指示矿床存在的依据,为找矿勘查的准确性提供了有力保证,为找矿提供了新的思路和方法,对预测未知类型的矿床具有很大的优势,它是未来成矿预测发展的新动向和新趋势在多元信息集成的基础上,作者圈定了A级找矿远景区4个, A-1:大村远景区,A-2:灰山-东至岩-富隆厂-白秧坪远景区, A-3:白洋厂远景区, A-4:金顶远景区。4个A级远景区地质、地球物理、地球化学、遥感构造解译均指示有很好的成矿前景,并且区内均有已知矿点存在。更多还原

【Abstract】 Lanping Basin in Yunnan Province is an important nonferrous and precious metal metallogenic belt, which is one of sixteen main metallogenic belts of solid mineral resources in China. This paper has collected and analysed previous inofrmation in geology geophysics,geochemistry,remote sensing and mineral exploration,and makes an overall and systematical study about various ore-forming conditions and ore-forming forecast in Lapping basin, with the synthetic use of the modem advanced techniques and the theories of geophysics, geochemistry and remote sensing .1. Through remote sensing image processing, information extraction, geological interpretation and field research, author find out the faults and tectonic movement of Lanping basin.2. The regional 1:200 000 geochemistry stream sediment had been processed and maps were obtained. A number of significant geochemical anomalies region with the mineralization potential delineated.3. A comprehensive summary and analysis of the distribution, mineralization situation and deposit of Sanjiang zone where Lanping Basin is in was made.4. Multi-information played a full comprehensive analysis of various technical and theoretical advantages, to reflect on all the instructions to deposit the basis for the accuracy of mineral exploration and provided a strong guarantee for prospecting to provide a new way of thinking and methods , To predict unknown type of deposit, a great advantage, it is the future development of the new mineralization forecast trends and new trendsOn the basis of information integration, the author delineated 4 class A prospecting district, they are A-1: Dacun prospective vision, A-2: Huishan-Dongzhiyan-Fulongchang-Baiyangping Prospective vision, A3: Baiyangchang Prospective vision, A-4:Jinding Prospective vision. Geology, geophysics, geochemistry, remote sensing structural indicates a good prospect of mineralization in these four prospective visions, and the regions there are mines.更多还原
