Argon isotopic data for metamorphic minerals in rocks from the southern Quebec Appalachians

[Adapted from "About the GSA Data Repository", "http://www.geosociety.org/pubs/drpint.htm#aboutdrp"] The above data set may be dowloaded from the Geological Society of America (GSA) Data Repository, which is located at the following URL:"http://www.geosociety.org/pubs/drpint.htm". The GSA Data Repository is an open file where authors of articles in GSA journals can place information that supplements and expands on their article, will not appear in print, but may be obtained from GSA.
