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挖掘历史的格伦维尔年龄阿迪朗达克地下室。最近的研究表明，剪切带在格伦维尔省的折返中的重要性。本项目研究阿迪朗达克山脉西北部迦太基-科尔顿糜棱岩带Dana山变辉长岩和邻近Diana正长岩杂岩中离散剪切带的野外关系、矿物组合、矿物和岩石化学、流体包裹体、40 Ar/39 Ar冷却年龄和U/Pb年龄。建议的研究的目标是确定一些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后期后格伦维尔隆起/折返路径的区域，并提供一个更好的了解迦太基科尔顿糜棱岩区在这一折返历史的作用。

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.
