Oblique extensional tectonics in the Malawi Rift, Africa

Deformation and sedimentary evolution of the Lake Albert Rift (Uganda, East African Rift System)

“…Chorowicz and Sorlien, 1992;Corti et al, 2007;Morley, 2010). The eastern branch (or Kenyan rifts) extends from Lake Turkana in the north to a diffuse zone of extension referred to the Tanzanian Divergence in the south (Fig.…”

“…In contrast, the western branch, extending from the Azwa Precambrian lineament in the north to Lake Malawi in the south, corresponds to a succession of seismically active asymmetric rifts segmented by transverse fault zones (TFZ; e.g. Bosworth, 1985;Chorowicz and Sorlien, 1992;Ebinger, 1989b;Morley, 2010Morley, , 1999Rosendahl, 1987;Fig. 1b) and displays an alternating sense of asymmetry (Ebinger, 1989a).…”

Influence of rift obliquity on fault-population systematics: results of experimental clay models

“…Dauteuil and Brun, 1993). Field studies in both continental and ocean-ridge environments describe a complex interaction between displacement-normal and rift-parallel structures in oblique rift zones such as the Gulf of California (Withjack and Jamison, 1986;Umhoefer and Stone, 1996), the Gulf of Aden (Withjack and Jamison, 1986), the Hartford basin of eastern North America (Clifton, 1987;deBoer and Clifton, 1988), the Malawi rift of east Africa (Chorowicz and Sorlien, 1992), the Reykjanes Ridge south of Iceland (Murton and Parson, 1993;McAllister et al, 1995), the Mohns Ridge north of Jan Mayen (Dauteuil and Brun, 1996), and several grabens in the northern North Sea (Fñr-seth et al, 1997). In rifts oriented sub-perpendicular to the displacement direction, some fault populations have a fractal scaling that can be described by a power-law size distribution (Cowie et al, 1993b).…”

Remote sensing and field analysis of the Palaeozoic structural style in NW Libya: The Qarqaf arch a paleo-transfer fault zone between the Ghadamis and Murzuq basins

“…10). This tectonic style is analogous to the half-spoon fault tectonics inside the Tanganyika-Rukwa-Malawi strike-slip fault zone bordering the north-western end of Lake Malawi rift in Eastern Africa (Chorowicz and Sorlien, 1992).…”
