| 摘 要： | 通过对南京近郊汤山膨润土矿床的矿区地质、矿床地质特征的分析，阐明了该矿床的成因及其矿石的物化性能。综合研究表明，该矿床是以流纹岩及凝灰岩为成矿原岩，在特定的条件下，经热液蚀变改造而形成的矿床。此矿床之矿石属钙基膨润土，经适当选矿后可用于深加工。

| Abstract: | Based on the study of the geological features, the genesis of Tangshan bentonite deposit on the outskirts of Nanjing is elucidated and its physico chemical properties are investigated. The original rocks of the mineral deposit are rhyolite and tuff. Due to hydrothermal alteration under proper conditions the ore can be formed. It is also shown that the bentonites are calcareous ones. After proper ore dressing, the ores can be used for deep procession. |
