    dct:description "This dataset accompanies planned publication 'Unmixing multiple metamorphic muscovite age populations with powder X-ran 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.  Samples collection was supervised by Ryan McAleer, Gregory Walsh, and Peter Valley of the USGS." ;
