Abstract:
Based on the current data and field research,Zha'ertaishan in the midwest of Inner Mongolia was taken as research object; Zha'ertaishan Group was divided; the geochemical characteristics were discussed; and the ore-bearing potential was evaluated. The result showed that Mesoproterozoic Zha'ertaishan Group, as a set of epimetamorphic rock series, consisted of clasolite, macker, siltite and carbonatite in a rift system, and was divided into Shujigou, Zenglongchang, Agulugou and Liuhongwan Formations from bottom to top; depositional environment of Zha'ertaishan Group showed the characteristic of normal transgression and regression sequence “continental facies→normal marine facies→semi-enclosed sea facies or bathyal facies→littoral facies”; Zha'ertaishan Group showed the element combinations “pro-scrap→pro-carbonate→siderophile and sulphophile→pro-scrap and pro-carbonate mixed” from bottom to top in the longitudinal; the correlation of rock constituents and metallogenic element was significant; argillaceous, calcareous and mafic rocks were rich in Pb, Zn and S-Fe; siliceous rock was rich in Cu, and the relationship between the content of organic carbon and the scale and quality of mineral deposit was positive eat and flow; the different stages of tectonic and the evolution of sedimentary environment caused the uneven distribution of elements, and it showed the change of ore-bearing potential from east to west, and particularly, Jiashengpan-Shanpiangou zinc poly-metallic deposit was poor in Cu, rich in Zn and a little accompaniment elements in the eastern part, several deposits in Langshan Area showed symbiotic Cu, Pb and Zn, rich in Cu, poor in Pb and Zn and many accompaniment elements in the western part.
