| 摘 要： | 对桂西地区铝土矿及其围岩系统取样,进行了微量元素分析。结果表明,原生铝土矿的成矿母岩主要为下二叠统茅口灰岩,其次有少量古陆风化物的加入;区内原生铝土矿形成于海相的沉积环境,堆积型铝土矿由原生沉积型铝土矿风化淋滤而成。

| Abstract: | Some primary and cumulated types of aluminum multi-metal deposits occur in Western Guangxi region,and there is a close relationship between these two types of deposits.Some samples from the bauxites and wall-rocks are collected and tested for minor elements.It is shown that the metallogenic parent rocks for primary aluminum multi-metal deposits are Maokou Formation limestone of Lower Permian Series with a few of weathering of old land.The primary bauxite was formed in a marine sedimentary setting and the cumulated bauxite was derived from weathering-leaching of primary bauxite. |
