Abstract
Mechanical stratigraphy controls the growth patterns and dimensions of relatively small normal faults, yet how its influences the development of much larger structures remains unclear. Here we use 3D seismic reflection data from the Outer Kwanza Basin, offshore Angola to constrain the geometry and kinematics of several normal faults formed in a deep-water clastic succession. The faults are up to 6.3 km long, 1.9 km tall, and have up to 44 m of throw. Aspect ratios and lower-tip throw gradients are greater for faults that terminate downwards at a c. 100 m thick, mass-transport complex (MTC) (up to 5.2 and 0.12) than for those that offset it (u... more
