Present-day stress and neotectonic provinces of the Baram Delta and deep-water fold–thrust belt

We present the first present-day stress orientation measurements across a delta and deep-water, delta toe fold–thrust belt. Stress and neotectonic data for NW Borneo reveal three discrete neotectonic provinces: an inverted, inner shelf province (where present-day maximum horizontal stress, σ H , is oriented margin-normal); an extensional, delta top province (σ H is margin-parallel), and a compressional, delta toe province (σ H is margin-normal). We interpret the delta top and delta toe data to reflect that compression in the fold–thrust belt is coupled to delta top extension and that the inverted, inner shelf province reflects the location of this system on an active margin.
