| 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 wallrocks 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. |
