Abstract

Late Quaternary faults at the proposed Point Conception LNG site consist of westerly-trending reverse faults that are parallel to bedding in the Pliocene bedrock beneath the terrace deposits, and southwesterly-trending cross-faults that offset displacements along the bedding-plane faults. Flexural slip and backthrust models have been proposed as mechanisms for site faults. While the faults exhibit some characteristics expected from the flexural slip model, data on shoreline-angle elevations on both flanks of the Government Point Syncline clearly prohibit flexure of this structure during the period of fault movements. A simple backthrust model does not expalin the spacing of site faults, but an antithetic model taken from ramp regions of overthrusts could explain this characteristic.--Modified journal abstract.
