    非洲大陆构造单元划分

    • 摘要: 非洲大陆地质演化历史悠久,矿产资源丰富。综合已有研究成果,对非洲大陆地质背景、构造单元划分及主要构造单元特征进行简要总结。非洲大陆跨特提斯和冈瓦纳两大构造域,大部分属于冈瓦纳构造域,主要由太古宙—古元古代结晶基底、上覆盖层和泛非构造带组成。根据非洲大陆地质背景和构造演化,在前人研究的基础上,将非洲大陆划分为2个一级构造单元,10个二级构造单元和55个三级构造单元。这些不同级别的构造单元较全面地概括了非洲大陆的地质面貌。

       

      Abstract: Africa has a long history of geological evolution and rich in mineral resources. Based on the previous research results, this paper summarized the geological background, division of tectonic units and characteristics of major tectonic units. The African continent is composed of Tethys tectonic domain and Gondwana tectonic domain, most of which belong to the Gondwana tectonic domain. It is mainly composed of Archean to Paleoproterozoic crystalline basement, overlying strata and Pan-African tectonic belt. According to the geological background and tectonic evolution of the African continent, combined with previous studies, the African continent can be divided into 2 grade Ⅰ tectonic units, 10 grade Ⅱ tectonic units, 55 grade Ⅲ tectonic units. These different grades of tectonic units give a comprehensive overview of the geological characteristics of the African continent.
