Part of the Frontiers in Sedimentary Geology book series (SEDIMENTARY)


The Wilmington Fan consists of three subdivisions. These are the upper fan, a truncated mid-fan, and the lower rise hills province. Wilmington Fan differs from most fans in two important aspects: 1) at the present, most sand crossing this portion of the passive continental margin escapes to the adjacent Abyssal Plain, and 2) bottom currents are important in fan development. Over the entire fan, most sediment has been deposited by bottom current-related processes. The lower rise hills formed by bottom currents restricts fan lobe formation on the lower continental rise by channeling the turbidity currents through numerous troughs between the rise hills.
