Evolution of the central Texas shoreface

Cross-section of profile 1, located offshore Matagorda Peninsula. Shoreface 1, shoreface 2 and the bounding surfaces are shown. Deposition of Shoreface 1 occurred between 8,000 to 4,500 years BP, based on correlation to Sabine Bank, offshore east Texas. Shoreface 1 is contained within the transgressive systems tract. A rapid rise in sea level occurred about 4,000 years BP associated with ravinement surface 2. From 3,500 years BP to present the modern highstand shoreface 2 has prograded and downlapped onto marine and distal lower shoreface sediments.
