DEPOSITIONAL MODEL-AXIAL MARGIN DELTA

This block model shows the subsurface configuration found at an axial margin delta system in a tropical rift valley lake. Such settings are typically major entry points for clastic material introduced into rift basins. Principal elements in the model include stacked progradational deltas, subaqueous fault controlled channels, and deep-water, organic-rich, hemipelagic sediments. Most subsidence in this part of the rift valley is accommodated by displacement on the main basin border fault.
