Geological Characteristics and Genesis of Key Metals in Huajian Bauxite and Aluminium-bearing Rock Series in Northern Guizhou Province
Taking the Huajian bauxite deposit in Anchang Town,Zheng'an County as the research object,the geological characteristics of the bauxite deposit and associated lithium resources in Dazhuyuan Formation are studied by geological mapping,sparse surface engineering trough exploration,deep engineer-ing drilling and sample testing and analysis.The results show that both bauxite and Li,the key metal of alu-minum-bearing rock series,exist in the middle and upper part of aluminum-bearing rock series of Dazhuyu-an Formation.Bauxite is mainly enriched in the north of the middle of the study area,and the thickness change of Al-bearing rock series is positively correlated with the enrichment of bauxite and associated ele-ment Li.When the thickness is less than 3 m,there is generally no ore.The content of Li is usually high in dense and clastic bauxite(rock),and a small amount in bean oolitic bauxite,but not in general earthy baux-ite.The concentration of Al2O3 and Li has a coupling relationship.When the content of Al2O3 is less than 55%,the concentration of Li is positively correlated with it,and when the content is great than or equal to 60%,there is no lithium ore.The correlation between Li content and SiO2 is not obvious,and Fe2O3 ores with higher Li content is generally lower.
