The Sorong Fault Zone Project
This technical report presents a comprehensive multi-disciplinary study of the Sorong Fault Zone in Eastern Indonesia, a region characterized by complex tectonics at the junction of the Eurasian, Philippine Sea, and Australian plates. The project establishes a regional geochronological and stratigraphic framework for the islands of Halmahera, Morotai, Bacan, Obi, and Waigeo. Utilizing geological mapping, gravity surveys, and isotopic dating (Sm-Nd, Rb-Sr, and K-Ar), the study identifies major fault strands and examines the exhumation and emplacement processes of continental fragments and ophiolitic rocks within the strike-slip system. The findings provide significant insights into the tectonic evolution of the region, emphasizing the interplay between subduction, collision, and lateral fault movements from the Palaeozoic to the Neogene.
