Stratigraphic and Structural Evolution of a Jurassic Seaway,Southeastern Gulf of Mexico

本研究是对墨西哥湾构造史研究的延续。将进行四项工作：1)1977 - 1980年收集的5条地震剖面的再处理；2)利用GEOQUEST工作站对这些数据进行分析；3)编写海湾东南部地区综合报告，包括对古巴进行为期两周的实地考察；4)准备以东南海湾深侏罗系为目标的ODP钻井方案。本研究的具体目的是提高对东南海湾地区断裂和早期古地理的认识。一个更普遍的目标是研究大陆裂陷的过程和沿转换板块边界形成过渡地壳的过程。

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.
