Davis9908622This US-Argentina dissertation enhancement research proposal was submitted by Ms. Pilar E. Garcia, University of Arizona, under the sponsorship of Dr. George H. Davis. Ms. Garcia will work with Dr. Ernesto Cristallini of the Universidad de Buenos Aires in Argentina. She will be doing a detailed study of a well-exposed range in the Sierras Pampeanas of Northwest Argentina, to increase our understanding of the formation of basement-cored uplift mountain ranges.Basement-cored uplifts are irregular tectonic products because they occur several hundred kilometers from active plate margins where most mountains are usually formed, and because they involve brittle faulting and folding of continental, crystalline rocks at shallow levels within the crust. This anomalous nature of these uplifts makes their kinematics and dynamics of formation poorly understood. The chosen site is important because it has exposure of the basement-cover contact, which will permit observation at a critical interface. A better understanding of the structure of these ranges is critical to evaluate the formation of these tectonic elements and may lead to useful geometric and kinematic models. The understanding of foreland basement uplifts is a significant problem in structural geology.***

davis9908622this us-Argentina论文增强研究建议由亚利桑那大学Pilar E. Garcia女士提交，在乔治·H·戴维斯（George H. Davis）博士的赞助下。 加西亚女士将与阿根廷布宜诺斯大学的Ernesto Cristallini博士合作。 她将对阿根廷西北山脉pampeanas的暴露范围进行详细研究，以增强我们对地下室估计的抬高山脉范围的形成的理解。BASEMENT-COREMENT-COLDECODERCORED升高是不规则的构造产品，因为它们发生了数百公里从通常形成大多数山脉的活性板缘，并且因为它们涉及大陆岩石在地壳内浅层的脆性断层和折叠。 这些隆升的这种异常性质使得它们的运动学和形成动力学知之甚少。 选择的位点很重要，因为它具有地下室覆盖接触的暴露，这将允许在关键界面上观察。 更好地理解这些范围的结构对于评估这些构造元素的形成至关重要，并可能导致有用的几何和运动学模型。 在结构地质学中，对前陆地下室的理解是一个重要的问题。***
