Major and trace element analysis of the Portage Lake volcanics from the Keweenaw Continetal Flood Basalt Province

This data set contains major and trace element analysis for a suite of basalts from the Portage Lake volcanics. The Portage Lake volcanics are a temporal sequence of flood basalts located in Northern Michigan that were deposited within the failed Midcontinent Rift. Major and trace elements were measured using XRF and LA-ICP-MS whole rock analysis. Major elements are reported in wt%, while trace elements are reported in ppm. This dataset acts as supplementary material to our manuscript.
