中文摘要
该建议是为了进行实地和实验室调查, 三大盆地新近纪地质历史 (Azua、恩里克约和圣胡安), 位于加勒比板块的北方边界地带。 的 这里的整体海洋序列是已知的海退,但缺乏 年代地层学和古生态学的可靠信息 阻碍了盆地演化和构造作用的分析。 的 建议的古生态学,将提供这些信息,并应 从而更好地了解新近系沉积和 伊斯帕尼奥拉岛的结构发展。 结果应该是 对加勒比板块运动的进一步了解, 伊斯帕尼奥拉岛的三重连接点
英文摘要
The proposal is for a field and laboratory investigation of the Neogene geological history of three interconnected basins (Azua, Enriquillo, and San Juan) in southern Dominican Republic, within the northern boundary zone of the Caribbean Plate. The overall marine sequence here is known to be regressive, but a lack of dependable chronostratigraphic and paleoecologic information has impeded the analysis of basin evolution and tectonism. The proposed paleoecology, would provide this information, and should lead to a better knowledge of the Neogene sedimentary and structural development of Hispaniola. The result should be an improved understanding of the movements of the Caribbean plate at the Hispaniola triple junction in the last thirty million years.
