中文摘要:
      [摘要]在草原覆盖的勘查盲区,如何选择有效、合理、经济的技术方法组合寻找隐伏的矿产资源, 是目前国内外矿产勘查领域共同面临的重要问题。本文以内蒙古镶黄旗道郎和都格矿区为例,采用地 质填图、地面高精度磁测、放射性、高密度电法、甚低频、x 荧光测量、钻孔等多种方法对研究区进行了初 步勘查,结果表明该区存在广阔的铜钨矿找矿前景,其中详细介绍勘查该类型矿床的技术方法与组合顺 序特征,实践表明,对应该类型覆盖区,应用地质填图、磁法扫描、Niton 荧光仪快速化探测量和高密度电 阻率法是有效的方法组合。
英文摘要:
      Abstract:Through the petrology and geochemistry research for the Beilekuduke granite, in Kalamaili region, East Junggar, Xinjiang, the relations between the Beilekuduke A-type granites and tin deposit are discussed. The research shows that biotite granites are actually typical aluminous A-type granites character鄄 ized by high Si, low Al, depleted Ca and Mg and abundant alkali. The value of the FeOt/ MgO is high. Rb, K, Th and other large-ion lithophile elements and Zr, Hf high field strength elements are enriched, and Ba, Sr, Nb, Eu are depleted, Eu shows negative model and REE was flat “V冶-shaped. The granite con鄄 tains relatively highter tin, and 8 belts of tin-bearing alteration are identified as a source of tin. This research provides a valuable reference for tin origin of this type deposit
