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.
