The mining area is located in the southern and western margin of the Fujian-Gan-Guangdong Caledonian fold belt in the South China fold system,and is an important producing area of Gaolin mineral resources.In this pa-per,the geological background and distribution of the mineralization of Gaolin deposit in this area are analyzed,and the geological characteristics such as structure and lithology are understood.Secondly,through the analysis of mineral composition,ore structure and ore properties of Gaolin ore,the physical and chemical characteristics of Gaolin ore are revealed.Then,through the study of related geological theories,the genetic mechanism of Gaolin deposit,including metallogenesis and process,is discussed.It is found that the ore-forming parent rocks of the Gaolin deposit are biotite monzonitic granite and two-mica monzonitic granite,which form a full weathering zone,semi-weathering zone and bedrock zone through secondary weathering residual.
