摘要
在广西大瑶山研究区充分融合近红外光谱技术与地球化学方法进行金、银、钨等矿产勘查示范性研究,利用便携式ASD光谱分析仪,在研究区开展点及剖面线多点测量,针对特定的几个指标建立地球化学异常之间比对分析,构建近红外光谱地球化学勘查模型,进而对成矿有利靶区进行圈定。新发现花岗斑岩脉(体)4处,高品位的金矿脉3条,圈定成矿有利靶区2处。同时,土壤近红外光谱剖面测量成果也可能为深部寻找隐伏岩体及矿化体提供有意义的找矿信息。
The near-infrared spectroscopy technology and geochemical methods have been fully integrated to carry out the demonstrative exploration study on gold,silver and tungsten mineral resources in Dayaoshan research area,Guangxi.The portable TSG Spectral Analyzer is used to measure at the points and prospecting lines in the study area.The comparative analysis between geochemical anomalies is established according to the several specific indexes,and the near-infrared spectrum technology and geochemical exploration model is constructed to delineate the favorable mineralization target areas.There are four new granite porphyry dikes(bodies),three gold ore veins of high grade and two favorable target areas of mineralization.Nevertheless,the survey result of soil near-infrared spectral profile can also probably provide the meaningful information for the deep exploration of concealed rock mass and mineralization body.
