Abstract

Evidence from continuous seismic-reflection profiles indicates that the steep slope off Florida and Yucatan were formed by construction of coral or algal reefs during the Cretaceous period. The uper continental slope and the shelf were formed by prograding and upbuilding of largely calcareous sediments off Florida and Yucatan, and of terrigenous sediments off Louisiana, Texas, and part of Mexico. The general structure off Louisiana and Texas was considerably altered by contemporaneous intrusion of salt diapirs.
