The present study is a continuation of the investigation on the tectonic history of the Gulf of Mexico. Four tasks will be undertaken: 1) reprocessing of five seismic profiles collected between 1977 and 1980; 2) analysis of these data using a GEOQUEST workstation; 3) preparation of a regional synthesis of the SE Gulf, including two-week field excursion on Cuba; 4) preparation of an ODP drilling proposal that targets Jurassic rocks in the deep SE Gulf. The specific object of this study and the ensuing drilling program is to improve the understanding of the breakup and early paleogeography of the SE Gulf region. A more general goal is to study the processes of continental rifting and creation of transitional crust along a transform plate boundary.

本研究是调查的继续 墨西哥湾地质构造史的研究四项任务将 （1）重新处理五个地震剖面 1977年至1980年收集的数据; 2）对这些数据的分析 使用GEOQUEST工作站; 3）准备区域 东南海湾的综合，包括为期两周的实地考察， 古巴; 4）编制ODP钻探建议， 东南海湾深处的侏罗纪岩石。这个的具体目的 研究和随后的钻井计划是为了提高 对东南部断裂和早期古地理的认识 海湾地区。一个更普遍的目标是研究 大陆裂陷和过渡地壳的形成沿着a 转换板块边界
