Extensional Tectonic on the Asymmetrical Formation of the Makassar Basin

Abstract

Several problems in the Makassar Strait area related to the type of extension tectonic at the opening of the Makassar Strait and the formation of the Makassar Basin until now have never met a solution. The purpose of this review is to convey latest views and descriptions in Systematic Literature Review (SLR) based on articles published from 1985 to 2020. The current overview consists of research objectives, methodology, results, and limitations. This SLR uses Scopus as a database to save and analyze existing research on the opening of the Makassar Strait and the formation of the Makassar Basin, including the overview of the geological order relationships on the mainland of West Sulawesi and the eastern Makassar Strait. The main finding is that the Makassar Basin is interpreted as a basin with an asymmetric structuration (horst and graben) with simple shear kinematics, namely the east block mechanism (West Sulawesi) which stretches and moves eastward through mega-shear electric faults. The use of primary data as supporting data from writing this article also conveys a new interpretation of the presence of marine shale source rocks in West Sulawesi and source rocks of lacustrine shale in the eastern Makassar Strait.
