Figure 1

Figure 1. Cartoons demonstrating convergence within a channel, with and without associated levee/overbank deposits. (a) Strata within the channel show no significant convergence, (b) strata within the channel converge toward both west and east channel margins, (c) strata within the channel do not converge at the margins, but levee/overbank deposits do. (d) A combination of cases (b) and (c), where strata within the channel and levee/overbank deposits both converge at the channel margins. Azimuths of reflection convergence are defined by the color wheel. Interpretation courtesy of AAPG member Supratik Sarkar, University of Oklahoma.
