Structural control of fluid flow on a carbonate platform margin: an example from the Otavi Mountainland, Namibia

Abstract

The present study focuses on the northwestern OML, southwest of the mining town of Tsumeb. The dominating structure in this area is the NW-SE striking Guinas Fault. The Guinas Fault is a shear zone that divides an area, which is different in sense of stratigraphic features, the grade of pre-, syn- and post- Damaran deformation and the type and grade of mineralisation. The northern area is enriched by Cu-rich base metal sulphides, whereas the southern area is almost barren.
