摘要: A compilation of ground-water exploration data in southeastern Botswana reveals that the occurrence ground water is not primarily controlled by large-scale fracture systems and lithologies, but folds Precambrian basement. Two sets superimposed synforms antiforms generate a “chess-board” pattern dome basin structures. Successful boreholes well fields appear to be preferentially situated areas where intersect, suggesting tectonic basins coincide with basins. Small-scale fractures favorable lithologies doubtless improve permeability within basin, subordinate determining distribution aquifer characteristics.
