| 摘 要： | 对宁武煤田轩岗矿区13个煤矿2#煤采集了98(含夹矸)个样品,运用煤地球化学以及沉积学等学科理论知识,结合X射线荧光光谱分析(XRF)、电感耦合等离子质谱分析(ICP-MS)等技术手段对样品进行测试分析。结果显示,宁武煤田轩岗矿区2#煤中锂的载体主要为硅酸盐矿物。锂元素含量总体变化呈北高南低的趋势,北部矿区沉积物源主要是来自北部阴山古陆和吕梁半岛的花岗岩、玄武岩和沉积岩类,南部矿区沉积物源主要是沉积岩类,相对于北部较为单一。

| Abstract: | Total 98 samples of coal No.2(including partings)have been acquired from 13 coalmines in the Xuangang mining area,Ningwu coalfield.Based on coal geochemistry and sedimentology etc speculative knowledges,combined with X-ray fluorescence spectroscopy analysis(XRF),inductively-coupled plasma mass spectrometry analysis(ICP-MS)etc technological means have carried out tests and analyses.The results have shown that the carriers of lithium in coal No.2 have mainly silicate minerals.Lithium element content presents north high south low trend as a whole.Mining area north part sedimentary provenance is mainly from the Yinshan old land to the north and the Lyuliang peninsular granite,basalt and sedimentary rocks,while south part sedimentary provenance is mainly sedimentary rocks,rather unitarycompared with the north part. |
