CRUSTAL STRUCTURE OF THE MAKASSAR BASINAS INTERPRETED FROM GRAVITY ANOMALIES : IMPLICATIONS FOR BASIN ORIGIN AND EVOLUTION

Dr. B. Situmorang

Abstract


The gross enistal structure of the Makassar basin has been interpreted from gravity anomalies in confunction with bore hole information and seismic reflection data, Considerubly attenuated conrinental crust appears to underline the basin which reflect a single episode of continental rifring, that has been active in the area during Eocene. Lower Miocene times. The implication of that interpretation for tectonic model are discussed and the overall evolution of the basin fromĀ  Middle Jurassic onward proposed.
