新疆清白山铅锌矿遥感找矿信息提取及遥感找矿模型探讨

Remote sensing information extraction and exploration model of qingbaishan lead zinc mine,Xinjiang

层控碳酸盐岩型铅锌矿是我国主要的铅锌矿类型[1],因其分布范围广泛且地质演化过程复杂,在西北地区一直以来比较难开展大范围的相关地面调查工作,对西北地区铅锌矿找矿工作造成较大的阻挠。随着多光谱遥感找矿技术的不断发展,其在矿产勘查已取得良好的成效。鉴于此,本论文以新疆清白山地区铅锌矿床为研究区,研究矿区找矿信息提取,利用LANDSAT7数据重点对研究区内主要岩性组合、构造形迹进行解译,提高原填图精度,利用LANDSAT8(OLI)数据提取蚀变信息异常结合以往基础地质资料进行综合分析,总结遥感找矿模型,为今后寻找同类型的矿床提供借鉴和参考。

Stratified carbonate-type lead-zinc deposits are the main types of lead-zinc deposits in China [1].Because of their wide distribution and complex geological evolution,it has been difficult to conduct large-scale related ground investigations in the northwest region.The lead-zinc ore prospecting work in the Northwest has caused greater obstruction.With the continuous development of multispectral remote sensing ore prospecting technology,it has achieved good results in mineral exploration.In view of this,this paper takes the lead-zinc deposit in the Qingbaishan area of Xinjiang as a research area,studies the extraction of prospecting information in the mining area,and uses LANDSAT7 data to interpret the main lithological combinations and structural features in the research area to improve the accuracy of the original mapping.Using LANDSAT8 (OLI) data to extract alteration information anomalies combined with previous basic geological data for comprehensive analysis,summarize the remote sensing ore prospecting model,and provide reference for finding similar types of deposits in the future.
