Paired Zones of Divergence and Convergence in Orogenic Belts: A Field Study in Western and Central Cuba

这个项目是为了调查加勒比“板块缓冲区”的各个方面，这是一个复杂的区域，由夹在大得多的北美和南美板块之间的小板块组成。古巴岛在晚白垩世至晚始新世经历了褶皱冲断带的挤压和发展，这是尤卡坦盆地、开曼海槽和尼加拉瓜隆起的裂谷和海洋沉积的间隔期。该项目将对在古巴收集的样本进行分析，以测试古巴造山带的分歧区和汇聚区配对模型--这些领域得到了非联邦来源的支持。结果应有助于澄清加勒比地区在多大程度上出现了同步的板块分歧和汇聚。

This project is to investigate aspects of the Caribbean "plate buffer zone" which is a complex area of small plates wedged between the much larger North and South American plates. The island of Cuba experienced compression and development of a fold and thrust belt during late Cretaceous to late Eocene, an interval of rifting and marine sedimentation in the Yucatan Basin, the Cayman Trough and along the Nicaragua Rise. This project will analyze samples collected in Cuba in order to test a model of paired zones of divergence and convergence in the Cuban orogenic belt -- the field aspects being supported by non-federal sources. Results should help clarify to what extent synchronous plate divergence and convergence has occurred in the Caribbean.
