Os- and Pb-isotope data for Laacher See tephra (Germany)

The data here includes the Os-and Pb-isotope data for Laacher See tephra and some East Eifel alkaline lavas measured at Radiogenic Isotope Geochemistry Laboratory, Dartmouth College. The dataset has been used in conjunction with published geochemical and isotopic data to draw inferences about the magmatic evolution and mantle source(s) of Laacher See. This data set is a part of the manuscript that will be submitted to Chemical Geology for publication.
