Petrologic Investigation into the P-T History of the Adirondack Mountains New York

该项目的直接目标是确定变质带的分布，变质峰温度和压力，以及阿迪朗达克山脉麻粒岩相岩的P-T路径。通过电子探针获得的矿物分析将与P-T- x计算一起使用，以约束峰值变质条件，而通过x射线测绘等技术确定的矿物分区将阐明推断P-T路径所需的反应历史。这些结果将最终对变质作用的起源和相关构造过程的性质提供约束。

The immediate objectives of this project are to determine the distribution of metamorphic zones, the peak metamorphic temperatures and pressures, and the P-T paths for granulite facies rocks of the Adirondack Mountains. Mineral analyses obtained by electron microprobe will be used with P-T-X calculations to constrain peak metamorphic conditions, and mineral zoning determined by techniques such as X-ray mapping will elucidate the reaction histories necessary to infer P-T paths. The results will ultimately provide constraints on the origin of the metamorphism and on the nature of associated tectonic processes.
