Geochemical and 40Ar/39Ar Analytical Data of Rocks from Glacier Bay National Park and Preserve

This data set contains major and trace element geochemical data and 40Ar/39Ar isotopic data and ages for rock samples collected during 2016 fieldwork in Glacier Bay National Park and Preserve. The plutonic rock samples were collected for radiometric age determinations to test for the presence of the Late Jurassic to Early Cretaceous (130-160 Ma) Saint Elias suite. The age analyses indicate that all the dated plutons are too young to be included in the Saint Elias suite.
