Neogene uplift and deformation in the northeastern Bird’s Head Peninsula, West Papua, Indonesia: consequences of oblique plate convergence

Pacific-Gondwana Permo-Triassic Orogenic Belt with Lesser Overprinted Cenozoic Deformation, Eastern Bird Head Peninsula, West Papua, Indonesia

“…The transition from one to the others is seamless as is apparent from Figure 3. The Central Bird Head Monocline formed during uplift of the Kemum High potentially in Quaternary, but may extend into Pliocene (Decker et al, 2009;Saputra, 2021;Saputra et al, 2022). The uplift would appear to be younger than formation of the Lengguru Fold Belt, although it cannot be ruled out that they partially overlap.…”

“…New Zealand and New Guinea, Figure 1; Cawood, 2005;Torsvik and Cocks, 2013). In the northern Bird Head Peninsula of northwestern New Guinea (eastern Indonesia), the Gondwana orogenic belt is exposed in the Kemum Block (Figure 2), a Late Cenozoic uplift bounded on its southern side by the Central Bird Head Monocline (Figure 3; Pieters et al, 1985;Decker et al, 2009;Saputra, 2021). The Cenozoic uplift also extends to the Cendrawasih Bay (Kusnida et al, 2023).…”
