太古宙花岗岩-绿岩地体主要是以重力变形样式并伴随有花岗岩浆以及底辟深成岩体的侵位为特征。绿岩带与其周围花岗岩地体之间关系的特征模式(Macgregor,1951和Anhaeusser等1969的“花岗岩-绿岩模式”)可以从较大范围内予以论证。本文主要以南非巴伯顿山地为例,通过一些示意图和照片说明在太古宙绿岩带及其周围的花岗岩地体内常见的各种具有代表性的构造类型。
The Archean granite-greenstone is mainly characterized by gravity deformation patterns accompanied by granitic magma and emplacement of diagenetic plutons. The characteristic patterns of the relationship between the Green Belt and its surrounding granite (Macgregor, 1951 and Anhaeusser et al., 1969, Granitic-Greenstone Patterns) can be demonstrated in a larger context. This paper takes Barberton Mountain in South Africa as an example to illustrate some representative tectonic types that are commonly found in the granitic terrains of the Archean greenstone belt and its surroundings through some diagrams and photos.
