摘　　要：矿区位于华南褶皱系闽赣粤加里东褶皱带南西缘,是重要的高岭土矿产资源产地。本文通过对该地区高岭土矿床的成矿地质背景和分布情况分析,了解了其构造、岩性等地质特征。其次,通过对高岭土矿石的矿物组成、矿石结构和矿石性质的分析,揭示了高岭土矿的物化特征。然后,通过对相关地质学理论的研究,探讨了高岭土矿床的成因机制,包括成矿作用和过程方面的探讨。研究发现,该高岭土矿床的成矿母岩为黑云母二长花岗岩和二云母二长花岗岩,经次生风化残积形成全风化带—半风化带—基岩带,属原地风化成矿作用。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.
