...A.O. ALAO; D. MIKEŠ Abstract Basin subsidence analysis, employing the backstripping method, indicates that two fundamentally different basin-generating mechanisms controlled the Tanqua depocentre development in the southwestern Karoo Basin, South Africa. On one hand, the subsidence curves display...

.... In the Tanqua–Karoo Basin (South Africa), seven wells were drilled into fine-grained sand-rich basin-floor fans and interfan mudstones to supplement outcrop data. Three close-to-outcrop wells proved useful in establishing characteristic log responses of the main architectural elements identified from the nearby...
