Oregon Continental Margin Structure and Stratigraphy: A Test of the Imbricate Thrust Model

  • L. D. Kulm

Abstract

The Cenozoic structural and stratigraphic framework of the Oregon continental margin records several intervals of significant tectonism (uplift) with subsequent erosion and truncation of older structures. During late Cenozoic time this framework displayed many of the characteristics of a fore-arc structure defined by Karig (1970). It is also characterized by a substantial amount of continental accretion, interpreted to be the result of underthrusting of the oceanic plate. The compressional thrust model (Seely, et al., this volume; Burk, 1968) offers the best explanation for the late Cenozoic evolution of the Oregon margin.
