WebLocally, fold-thrust development can localize on pre-existing structures. Thus consideration of the precursor geology is essential for structural interpretation. Using a case study from the Papuan Fold Belt we show that even with seismic data, assessing the role of basement in structural development can be uncertain. WebJan 1, 2024 · The fold-thrust belt is controlled by two detachments in the Cretaceous and Eocene. • Detachment folds developed within an eastward migrating deformation front. • Prograding units in the Sulaiman Foredeep give evidence for Paleogene crustal loading. • A variety of Cenozoic petroleum exploration plays are identified.
