| Four > 100 km(3) mass-transport deposits (MTDs) identified from their morphology and seismic facies across the Matakaoa Margin and Raukumara fore-arc basin, NE New Zealand, constitute the Matakaoa Submarine Instability Complex (MSIC). MSIC originates from a 45-km-wide, 1100-m-high reentrant in the continental slope. The deposits resulted from three mass-failure events: ( 1) The Raukumara Slump is identified from the collapsed NW flank of an anticline at the northern end of the reentrant and imbricate structures at its distal end, overlying a flat decollement over a > 50-km distance. The slump age is roughly estimated between upper Miocene and lower Pleistocene. (2) The Matakaoa Debris Avalanche (MDA) is subdivided into a similar to 260-km(3) blocky... |
