【摘要】：四川甲基卡矿田是中国乃至于世界上锂矿资源最集中的地区之一,目前运用遥感技术开展甲基卡型锂矿的研究工作尚较为薄弱,文章运用遥感技术在甲基卡特殊地貌区开展找矿填图应用研究,建立了研究区典型岩石及矿物的波谱数据库,总结了研究区黑云母片岩、十字石片岩、十字石堇青石片岩、角岩、二云母花岗岩、含锂辉石伟晶岩、无矿伟晶岩、石英脉、长石斑晶、锂辉石单晶、云母、绿柱石的波谱特征;之后分别基于中等分辨率遥感数据Landsat 8和高空间分辨率遥感数据Geoeye-1进行图像处理和信息提取,开展了地质填图应用初步研究。研究结果表明遥感技术作为一种新兴的技术手段,对甲基卡型锂矿的填图及找矿具有重要的指导意义,可以作为今后地质找矿工作的"先头兵"。
[Abstract]:The Sichuan methyl card field is one of the most concentrated areas of lithium in China and in the world. At present, the research work of using remote sensing technology to carry out the methyl card lithium deposit is still relatively weak. In this paper, the application of remote sensing technology in the special geomorphologic area of methyl card is carried out and the spectrum number of typical rocks and minerals in the study area has been established. According to the library, we summarized the study area of biotite schist, cruciform rock, cordierite schist, corner rock, two mica granite, spodumene pegmatite, ore free pegmatite, quartz vein, feldspar, spodumene single crystal, mica, and beryl, and then based on medium resolution remote sensing data Landsat 8 and high spatial resolution remote sensing, respectively. The data Geoeye-1 carries out the image processing and information extraction, and has carried out the preliminary study on the application of geological mapping. The results show that the remote sensing technology, as a new technical means, has important guiding significance for the mapping and prospecting of the methyl card lithium deposit. It can be used as a "pioneer" in the future geological prospecting work.
