摘要：冰岭风化壳型重晶石矿位于海南省儋州市，作为我国主要重晶石矿床类型，这种矿床主要赋存于二叠系峨查组第四段地层中，矿层受小褶曲控制，脉岩受裂隙或断层构造控制。本文结合工作区内重晶石矿的地质特征和矿产分布，分析区域成矿规律与成矿要素，明确区域成矿模式，为下一步工作区重晶石矿床的找矿指明方向。

Abstract： Bingling weathered crust barite deposit is located in Danzhou City， Hainan Province， as the main type of barite deposit in China， this deposit mainly occurs in the fourth member of the Permian Echa Formation， and the ore layer is controlled by small folds， and the vein rock is controlled by fractures or fault structures. In combination with the geological characteristics and mineral distribution of barite deposits in the work area， this paper analyzes the regional metallogenic laws and elements， defines the regional metallogenic model， and points out the direction for further prospecting of barite deposits in the work area.

Keywords： barite; geological characteristics; metallogenic laws; metallogenic model; Bingling
