Aspect Ratios in Coarse-Grained and Fine-Grained Submarine Fan Channels

Anne M. Delery, Arnold H. Bouma

ABSTRACT

Most turbidite complexes can be placed into two end-members: coarse-grained, sand-rich and fine-grained, mud-rich. These two classes display large differences in sandstone/shale ratio and in the distribution of both lithologies. Both end members geometry have channels near the base-of-slope, which become distinctly leveed on the middle fan, and are nonchannelized sheet sands in the middle and outer parts of the lower fan. The aspect ratios differ greatly, but finegrained systems tend to have an aspect ratio of 100:1. The ratio differences and channel fill characteristics can distinguish the type of end member visible on seismic records.
