摘要：冰嶺風(fēng)化殼型重晶石礦位于海南省儋州市，作為我國(guó)主要重晶石礦床類型，這種礦床主要賦存于二疊系峨查組第四段地層中，礦層受小褶曲控制，脈巖受裂隙或斷層構(gòu)造控制。本文結(jié)合工作區(qū)內(nèi)重晶石礦的地質(zhì)特征和礦產(chǎn)分布，分析區(qū)域成礦規(guī)律與成礦要素，明確區(qū)域成礦模式，為下一步工作區(qū)重晶石礦床的找礦指明方向。

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
