| 摘 要： | 川陕交界镇巴—城口震旦系毒重石成矿带，是我国唯一的毒重石成独立工业矿床的大型成矿带。毒重石矿层严格受Ｚｂ２ 地层控制。成矿介质为ＳＯ４ＨＣＯ３ － Ｃｌ－ Ｎａ － Ｋ 型热卤水。成矿场所为受同生断裂控制的拗陷盆地。后期快速堆积的重晶石矿层是ＢａＣＯ３ 矿层的保存条件。毒重石矿床属热水沉积成因层控矿床。

| Abstract: | Sinian witherite mineralized belt in Zhenba Zhengkou,the juncture of Shaanxi and Sichuan,is the only large scale witherite mineralized belt where witherite assembled to independent ore deposit.The ore bed was strictly controlled by upper Sinian strata.The ore forming fluid was the type of SO 4/HCO 3-Cl-K-Na hot brine,and ore forming area are depression basin controlled by growing fault.Barite bed that was quickly deposited onto wintherite bed is the preserving conditions of witherite deposits.Witherite deposits belong to stratabound deposits of hot water sedimentation. |
