Evidence of multiphase deformation in the Rajang-Crocker Range (Northern Borneo) from Landsat imagery interpretation: Geodynamic implications

Seismic images of a collision zone offshore NW Sabah/Borneo

“…We propose that the crustal shortening models (B, C) fit much better the data and are supported by onshore findings which confirm Pliocene, probably extending into the Pleistocene, compressional deformations (approximately N-S) in Sabah (Benard et al, 1990;Tongkul, 1994;Meng, 1999). The young volcanism in the Borneo Trough (see chapter discussion of selected lines) also indicates tectonic activity.…”

“…2) . The onshore area from the NW Sabah coast to the Mount Kinabalu intrusion is defined by predominantly thrust faults and some strike-slip faults (Benard et al, 1990;Tongkul, 1991Tongkul, , 1994. Indications for extensional movements are-apart from the offshore border area to Brunei-not distinct or absent.…”

“…A striking onshore structural element of this wide and highly complex deformation belt is the CrockerRajang mountain belt which extends along the central part of Borneo, from Sabah to central-south Sarawak ( Fig. 1; Hamilton, 1979;Benard et al, 1990;Hutchison et al, 2000). It is generally assumed that this mountain belt formed as an accretionary complex during south-directed subduction of a proto-South China Sea (Hamilton, 1979;Hall, 1996;Hutchinson, 1996;Meng, 1999;Pubellier et al, 2003).…”

Miocene and Pleistocene crabs (Crustacea, Decapoda) from Sabah and Sarawak

“…Lithologies include gneisses, amphibolites and other igneous rocks, which are interpreted as uplifted slices of the continental crust underlying Borneo (Leong 1974). Associated with the crystalline basement is an ophiolitic sequence dating from Cretaceous to late Eocene, informally termed the Chert-Spilite Formation (Clennel 1992;Rangin et al 1990). It is thought that these ophiolitic fragments were obducted during subduction of the Celebes and proto-South China Sea (Holt 1998).…”
