| By the geological mapping of, and light, thin slices of identification in Bao Ren TegeBaotou area, research, according to the sedimentary features of Jianshan formation, dividsJianshan formation detaily, identifies manganese-bearing strata; on this basis, the focus was onthe sedimentary facies analysis of Jianshan formation, discusses the causes and the formation ofmanganese ore controlling factors. The study concluded that: the Jianshan formation can bedivided into three sections, the second section and the third second are divided into two and threesub-sections.Among them, the second sub-section of Jianshan formation is manganese layer.Based on color, structure, primary sedimentary structures of rocks and spatial configuration ofthe study, as well as the comprehensive analysis of geological maps, the group identified fromthe Jianshan formation shore phase and phase two kinds of shallow sedimentary facies, shorephase No barrier can be broken down into sub-phase deposition of sandy coast and the barrierisland-lagoon sediment subfacies. Barrier island-lagoon subfacies is the main study area, theformation of manganese environment, controlling the formation and distribution of manganese.Take sedimentary environment ore-controlling factors as major，combine geophysical andgeochemical abnormalies and mineralization point lithologic features,point out2key prospectingtarget area,they are in northeast of Baorentege Manganese mines and east of Xierhuduge. |
