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

这个项目的重点是挖掘格伦维尔古老的阿迪朗达克地下室的历史。最近的研究表明剪切带在格伦维尔省发掘中的重要性。本项目旨在研究西北阿迪朗达克山脉Carthage-Colton Mylonite带Dana Hill Metagabbro和相邻的Diana正长岩杂岩中离散剪切带的场关系、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。提出的研究目标是确定一些时间上不同的变形事件的压力-温度条件。这些数据将用于评估该地区格伦维尔隆起/挖掘后的后期路径，并更好地了解迦太基科尔顿糜棱岩带在这一挖掘历史中的作用。

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.
