Gravity Evidence For A Possible Plate Tectonic Origin of Namaqua/Damara Structural Province Boundary In Namibia and Botswana

E. A. Emenike
KEYWORDS: Gravity anomalies, structural boundary, tectonic province, Gravity modelling and tectonic evolution

ABSTRACT:

Gravity anomalies in the vicinity ol the Namaqua and Damara tectonic provinces in Southern Africa posses extensive. pair of linear negative and positive ano.malies straddling one another on the basis of which the structural boundary can be mapped: Gravity modelling of ;the boundary indicates considerable tlilrusting of about .50 km of Damara belt over the Namaqua block.· Plate tectonic evolution is one of the ways in which the. juxtaposition of these structural blocks at varying age and thickness can be understood.
