| 摘 要： | 阜蒙县北窝铺膨润土矿床位于中生代断陷盆地——于寺盆地中,矿体呈层状、似层状主要赋存于白垩系下统义县组第一岩段火山碎屑岩中。通过矿石阳离子交换量分析和差热分析,确定为钙基膨润土矿床。该矿床的形成受地层控制,沉凝灰岩、凝灰质砂砾岩、流纹质晶屑玻屑熔结凝灰岩与矿床的形成有密切关系。

| Abstract: | Beiwopu Bentonite deposit in Fumeng county locates in Mesozoic faulted basin namely Yusi basin. The ore bodies occur in stratiform, stratoid mainly in the first lithologic unit pyroclastic rock of lower cretaceous Yixian formation. Through ore cation exchange capacity （CEC） analysis and Differential thermal analysis, Calcium base bentonite deposit has been determinate. The deposit formation is controlled by strata, and has the relationship with the sedimentary tuff, tuff gritstoneand and rhyolitic crystalvitric tuff. |
