Metallogenic Factor and Origin in Zunyi Bauxite Belt, Guizhou
摘要
Abstract
According to the geological achievements available,this paper uses the theories and ways of sedimentology and discusses the metallogenic factor and origin of Zunyi bauxite belt.The paper states that the bauxite is most probably formed on ancient karst basement from carbonate rocks in Palaeozoic Era.When paleostructure,paleogeography and paleoclimate are advantageous,the eluvial diluvium experiences laterization of calcium,degraded silicon and iron,decalcification and degraded magnesium,thus forming laterite-type bauxite.Then,the transgression that happened in Carboniferous caused the continuous hydrolyzation,which moved deposits into the pothole of ancient karst to form the gibbsite deposit.Finally,the upper terrane became thick,calefacient and dehydrated,and consequently formed the diasporite bauxite deposit.The genetic type of ore deposit is attributed to sedimentary bauxite deposit of former weathering crust and pothole of ancient karst.Its metallogenic epoch is thus determined to be Early Carboniferous Datangian.关键词
