Quantitative and geomorphologic parameterization of megaclasts within mass-transport complexes, offshore Taranaki Basin, New Zealand

Mass-transport complexes (MTCs) in sedimentary basins reflect the gravitational transport of sediments from shelf edge to abyssal plain. Megaclasts, large blocks hundreds meters long within MTCs, can record kinematic and information deemed essential understanding source-to-sink systems. Yet, deformation structures such megaclasts remain poorly understood. This study uses high-quality, three-dimensional (3-D) seismic reflection data deep-water Taranaki Basin offshore New Zealand analyze morphological character 123 propose a new classification scheme based on their morphometric properties. The are up 400 m tall, 1900 long, 1200 wide. In area, they high- moderate-amplitude features owing different lithologies continuous-to-contorted facies. be classified as undeformed, rotated, deformed, highly deformed internal deformational styles. Two kinds depressions observed basal shear zones further indicate whether transported or formed situ. Our demonstrates that quantitative parameterization provides important about processes more complete megaclast emplacement along continental margins.
