Tectonically induced lateral compression is taking place, resulting in pore volume reduction, sediment strengthening, and dewatering of collision complex through fault-controlled fracture permeability. More fluids and higher porosity material bracketing indurated rocks in the NAB are evidence of rapid burial and alternation of sediment during intense bursts of volcanism associated with tectonic subsidence of the basin, and/or surrounding island belts due to arc-wide lateral compression from collision.
