Abstract

The Hope basin is a Cenozoic basin off the coast of Alaska in the Bering Sea. Its initial formation was theorized to have occurred from right-lateral movement on the Kobuk fault, a strike-slip fault in northwestern Alaska. However, from an interpretation of newly reprocessed seismic lines from the southeastern portion of the basin, it is evident that distinct characteristics of strike-slip basins, as evaluated by past authors, are not present in the study area. Furthermore, a study of the tectonic history of the region lends itself to an alternate theory of orogenic collapse of the Herald Arch as the basin's originator.
