The Bumbeni Line - An Aligned Group Of N.E. Trending Bodies In Northern Natal

A characteristic of the African crust are numerous NE-SW trending<br>lineaments along which volcanic and sub-volcanic ring complexes, basalt<br>flows and acideous plutons predominantly occur.<br>One such lineament is the Bumbeni lineament (Fig. 1) which consists<br>of numerous igneous complexes and 13 can presently be identified (fig.<br>2). The majority of the complexes are buried and situated along a line<br>stretching from Sodwana Bay (northeastern Natal coast) through the<br>Hiuhiuwe and Umfolozi Game Reserves towards the southern boundary of<br>the Kaapvaal Craton (Fig. 1). The only exposed volcanic member along<br>the lineament is the Bumbeni Complex (Fig. 1) which can geophysicafly<br>be subdivided into two separate bodies namely Complex A, consisting of<br>acideous plutons and a ring dyke complex called Complex B.
