| 總結: | Title screen High concentrations of Al, Li, Ga, rare earth elements and yttrium, U and Ba in the Ordos Basinhave been reported separately by lots of authors. These elements have even formed coalassociated deposits in some coalfields. The purpose of this review paper is to summarize theiraccumulation mechanisms and set up a mode of occurrence of these elements in the entireOrdos Basin. The Al and rare elements show different patterns of distribution and affinityrelationships with organic and inorganic matter. The strong peraluminous granites and moyitefrom the Yinshan Oldland and Lu?liang Peninsula may be the main source of the Al and rareelements in the coals. The carriers of barium are witherite and strontianite, both of which are ofepigenetic origin. It is inferred that the barium was originated from the Ba-ore deposits in theblack shales in the Qinling Mountains, located to the south of the Ordos Basin. Uranium depositsoccur near the margin of the basin and are mainly hosted in sandstones of the Jurassic. Режим доступа: по договору с организацией-держателем ресурса |
