Abstract

The landward belt of the Kodiak Formation represents a sequence of lower Maastrichtian turbidites that was underplated to the Kodiak accretionary complex by duplex accretion. Evidence for duplexes exists on the mesoscopic and map scale. Duplex underplating can result in the uplift and thickening of accretionary prisms without necessarily deforming the overlying, previously accreted material and slope sediments. -from Authors
