Structural Styles in Western Sabah Offshore

Abstract

In S and central offshore Sabah, between Labuan and Mangalum, the main tectonic phase was in late Miocene, and led to the formation of steep, upthrusted, rather narrow anticlines separated by broad, deep, gently folded synclines. The anticlines ('ridges') may be related to basement-induced faulting. Further north, similar structural movements took place in the Pliocene between Mangalum and Kudat
