RUI: Determination of the Pressure-Temperature Time Path and Deformation History for the Carthage Colton Mylonite Zone, New York State

9725440约翰逊这个项目的重点是格伦维尔时代的阿迪朗达克地下室的挖掘历史。最近的研究表明，剪切带在格伦维尔省身体折返中的重要性。该项目旨在研究阿迪朗达克山脉西北部迦太基-科尔顿糜棱岩带中达纳山变质辉长岩及其邻近的戴安娜正长岩杂岩中离散剪切带的野外关系、矿物组合、矿物和块岩化学、流体包裹体、40Ar/39Ar冷却年龄和U/Pb年龄。拟议研究的目标是确定一些在时间上不同的变形事件的压力-温度条件。这些数据将被用来评估该区域晚期到格伦维尔之后的隆升/折返路径，并提供对迦太基科尔顿糜棱岩带在这一折返历史中的作用的更好的了解。

9725440 Johnson This project focuses on the exhumation history of the Grenville-aged Adirondack basement. Recent studies pint to the importance of shear zones in the exhumation of the Grenville-province. This project is to study the field relationships, mineral assemblages, mineral and bulk-rock chemistries, fluid inclusions, 40Ar/39Ar cooling ages and U/Pb ages from discrete shear zones within the Dana Hill Metagabbro and adjacent Diana Syenite Complex in the Carthage-Colton Mylonite Zone in the Northwestern Adirondack Mountains. The goals of the proposed research are to determine the pressure-temperature conditions of a number of temporally distinct deformational events. These data will be used to evaluate the late to post-Grenville uplift/exhumation path for the region and to provide a better understanding of the role of the Carthage Colton Mylonite Zone in this exhumation history.
