摘　　要：通过地质学和同位素年代学的分析方法,总结了鹅湖脉型高岭土矿床地质特征和富集规律。鹅湖黑云母二长花岗岩基成岩期末,演化分异的残余酸性尾浆沿裂隙充填形成的花岗斑岩脉群作为内生母体,之后长期遭受外生作用,形成风化壳控制的残积型砂质高岭土矿床。研究指出矿田内鹅湖高岭土矿区外围的北东和南西延伸方向及南部平行脉带仍有较好的找矿前景,丰富了人们对景德镇历史上使用的"高岭土矿床"主要工业类型及其矿床特征的认识,为景德镇瓷业提供后备资源保障。The geological characteristics and the pattern of enrichment of the vein-type kaolin deposits are summarized in Ehu town of Jingdezhen based on geological methods and the isotopic chronology analysis.During the late stage of the diagenesis of the biotite monzonite-granite batholith,the evolved and differentiated remanent acidic magma were filled in the fractures and fissures and created the granite porphyry dikes as the endogenous host rocks,and finally formed the residual-type sandy kaolin deposits which were confined to the weathering crust after long-term cycles of exogenic processes.Better exploration prospects are also expected in the NE and SW extensions around the periphery of the mining area and the paralled veins to the south of Ehu kaolin deposit,which is able to provide resource reserves for the porcelain industry of Jingdezhen.It also enriches the understanding of the deposit characteristics and the major industrial types of the kaolin deposits throughout the history of Jingdezhen.
