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

本项目的近期目标是确定 变质带的分布，峰期变质 温度和压力，以及麻粒岩的P-T路径 阿迪朗达克山脉相的岩石。 矿物分析 用电子探针获得的结果将与P-T-X 限制峰值变质条件的计算，以及 X射线等技术确定的矿物分带 映射将阐明必要的反应历史， 推断P-T路径。 结果将最终提供 对变质作用起源的制约 相关构造过程的性质。

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.
