| 摘 要： | 近年来,江苏南部发现了许多膨润土矿,矿点广布于镇江地区的溧阳、溧水、丹徒、句容及南京市郊的江宁县。其中多数矿点是由中生代陆相火山沉积岩系蚀变形成,呈层状、似层状产出,唯溧阳平桥膨润土是由花岗斑岩等超浅成侵入岩经热液蚀变形成,呈脉状产出,产状罕见。此类矿床质地纯净,是一种新型的优质膨润土矿。本文对溧阳平桥脉型膨润土进行了矿物学研究。

| Abstract: | An excellent kind of pure bentonite was found at Pinggiao in Liyan County,Jiang-su province.It is occurred as hydrothermal vein controlled by NNE trending faulted structure.The mother rock initially was a granite-porphyry.According to the laboratory studies,such as chemical,X-ray diffraction,DTA,IR,optical and electron microscopic analyses etc.,it belongs to a dioetahedral Ca-montmorillonite with the characteristics of Cheto-type. |
