Summary

This dataset accompanies planned publication 'Unmixing multiple metamorphic muscovite age populations with powder X-ray diffraction and 40Ar/39Ar analysis'. The 40Ar/39Ar and electron microprobe data are from samples adjacent to a lower greenschist facies shear zone in western New Hampshire. The geochronology coupled with the electron microprobe data provide a petrochronologic framework for the rocks studied in the manuscript. Sample collection was supervised by Ryan McAleer, Gregory Walsh, and Peter Valley of the USGS.

Purpose

Data were obtained so that the relationship of major and minor element microchemistry of muscovite to argon isotopic data from muscovite could be assessed at this locality. The greater goals were to constrain timing of tectonic events in western New Hampshire and to contribute to 40Ar/39Ar methodologies in metamorphic rocks. Data were shared to meet open data requirements.
