| 摘 要： | 苏皖凹凸棒石粘土矿床成矿时代为晚第三纪中新世，其赋矿层位主要为含矿岩系的顶部。通过对苏皖凹凸棒石粘土矿床成矿物质来源及成矿介质条件（ｐＨ值，氧化还原条件，温度及盐度等）的分析讨论，表明其成矿物质来自底板玄武岩（Ｎ＿１ＸＡ＿２），凹凸棒石粘土矿床便是玄武岩风化产物搬运到水盆地中通过沉积—成岩作用形成，与火山作用有关的热水溶液参与了成矿过程。其成矿介质为碱性，弱还原—还原，低盐度及低温的环境。

| Abstract: | The minerauzation epoch of attapulgite clay deposits,Which located at the top of ore bearing series in the border area of Jiangsu and Anhui Provinces is Miocene.Accordingto the study results about mineralization source,Ore forming mdeium,the attapulgiteclay deposits are formed in the shallow lacustrine basin under the conditions of alkalic,re-ducing and low salinity ,low temperaturewater medium.The mineralization source iS relat-ed to N_1XA_2 basalt.The hydrothermal solution being related to volcanic action is of certainsignificance to mineralization of attapulgite clay deposits. |
