Saini-Eidukat0073993This US-Argentina project funded by the Division of International Programs in the Directorate for Social, Behavioral and Economic Sciences and the Petrology and Geochemistry Program of the Directorate for Geosciences supports Dr. Bernhardt Saini-Eidukat of North Dakota State University, Fargo, to work with Drs. Daniel A. Gregori and Ernesto Bjerg at Universidad Nacional Del Sur in Argentina on a study of silicic magmatism in Northern Patagonia.This project is a geochronological, geochemical and radiogenic isotope study of silicic magmatism in Somoncura region of Northern Patagonia in Argentina. Its primary objective is to place the silicic rocks of Somoncura Magmatic Belt in a modern plate tectonic geologic context.This study of the origin of the silicic rocks in southern South America will help link these rocks with structural and tectonic studies and is important for testing models having a bearing on the break-up of the supercontinent of Gondwana. In addition to the PIs, undergraduate students from North Dakota State will be involved as well as a graduate student from Argentina. Facilities used will be those at Fargo State, Universidad Nacional del Sur in Bahia Blanca, Argentina, the University of Wisconsin-Madison, and Macalester College in Minnesota.***

Saini-Eidukat 0073993这个美国-阿根廷项目由社会、行为和经济科学理事会国际项目处和地球科学理事会岩石学和地球化学项目资助，支持法戈州立大学北达科他州的Bernhardt Saini-Eidukat博士与丹尼尔A.阿根廷南国立大学的Gregori和Ernesto Bjerg关于北方巴塔哥尼亚岩浆活动的研究。该项目是对阿根廷北方巴塔哥尼亚索蒙库拉地区岩浆活动的年代学、地球化学和放射性同位素研究。 它的主要目的是将索蒙库拉岩浆带的火山岩置于现代板块构造地质背景中。对南美洲南部火山岩起源的研究将有助于将这些岩石与构造和构造研究联系起来，对检验与冈瓦纳超大陆断裂有关的模型非常重要。除了PI，来自北达科他州的本科生和来自阿根廷的研究生也将参与其中。 使用的设施将是法戈州立大学、阿根廷巴伊亚布兰卡的南国立大学、威斯康星大学麦迪逊分校和明尼苏达州的马卡莱斯特学院。
