The distribution of selected critical elements in the sedimentary rocks of the Carboniferous coal-bearing series within the Polish Coal Basins is presented.Critical elements such as Be,Mg,Si,P,Sc,V,Co,Y,Nb,In,Sb,La,Ce,Hf,Ta,W,Bi were analysed using inductively-coupled plasma mass spectrometry(ICP/MS).Concentrations of elements such as Sb,Bi,In and,to a slightly lesser extent,Nb,as well as Sc,show average concentrations higher than those from the upper continental crust.The average concentrations of elements like Hf,Mg,P,Y,La,and Ce are slightly lower than in the upper continental crust.Other elements,such as Be,Co,Si,Ta,W and V have average concentrations that are similar,but slightly enriched or slightly depleted,relative to the upper continental crust.The research showed enrichment of some critical elements in the analysed samples,but not high enough that extraction would be economically viable.Statistical methods,which include correlation coefficients between elements and cluster analysis,reveal a strong positive correlation between elements like Be,Bi,Nb,Sc,Ta,W and V.Very high,almost total,positive correlation is also noted between La and Ce. 相似文献

吾人对於某区矿脉系之发育,与矿质之富集,能找出一定则与规律,则与学术及实用方面,不无特殊意义,窃以为利用单纯地质构造关系,探求填充矿脉发育所在,其可能性稍大,但矿质之富集,条件甚多,常因所在地质情形不同,及其他复 相似文献

‘南山砂岩系’一名,为早年洛采氏(L.Loczy)调查南山区地质时创立。以砂岩为主,夹石灰岩,有花岗岩侵入体,受强烈褶皱,劈开与片理俱甚发育,但变质作用,殊为轻微,无化石,其时代暂定为下部古生代或更老。其后俄博奇夫(Obrutschew)虽调查较详细,惟关 相似文献
