International: Characterization of High Pressure/Ultrahigh Temperature Alpine-Type Garnet Peridotite in Northern Dominican Republic

[0139490]本美洲项目提案请求支持北卡罗来纳州布恩市阿巴拉契亚州立大学的Richard N. Abbott博士对一种名为阿尔卑斯型尖晶石石榴石橄榄岩的不寻常变质岩进行研究，该变质岩最近由PI在多米尼加共和国加勒比海国家的奎瓦斯河中发现。阿博特博士将与圣多明各矿业/地质调查局的工程师P.V. Chavez和V. Silva以及圣多明各自治大学的Ivan Tavares博士合作。研究的主要目的是确定和绘制该岩石与同一单元中其他岩石之间的关系；找到巨石的来源，并在实验室分析样品。了解这些不寻常的岩石将有助于在更广泛的加勒比盆地起源背景下完善大安的列斯群岛起源的现有模型。确定这些橄榄岩巨石的地质来源将为加勒比地区这一地区发生的构造过程提供基本的第一手资料。多米尼加人将通过政府的四边形测绘计划参与该项目，并将受益于由此产生的地质图，这将有助于其自然资源的开发和管理。

0139490This Americas Program proposal requests support for Dr. Richard N. Abbott, Appalachian State University, Boone, NC, to conduct a research of an unusual metamorphic rock called Alpine-type spinel-garnet peridotite, recently discovered by the PI in the Cuevas River in the Caribbean nation of the Dominican Republic. Dr. Abbott will be collaborating with Engineers P.V. Chavez, and V. Silva, Direccion de Mineria (bureau of mines/geological survey),Santo Domingo, and Dr. Ivan Tavares, Universidad Autonoma de Santo Domingo. The principal objectives of the research are to determine and map the relationship between this rock and others in the same unit; find the source of the boulders, and analyze the samples in the laboratory. Understanding these unusual rocks will help to refine the current model of the origin of the islands of the Greater Antilles in the broader context of the origin of the Caribbean basin. Identifying the geological sources of these peridotite boulders will provide fundamental first order on the tectonic processes that have occurred in this part of the Caribbean. Dominicans will participate in the project through the government's quadrangle mapping program and will benefit from the resulting geologic map that will be useful for the development and management of their natural resource.
