Abstract
This dataset includes 234U/230Th chronologic data for lacustrine carbonates associated with Marshall drift in Marshall Valley, Royal Society Range. These samples are from ice-dammed lake deposits associated with a grounded ice sheet that blocked the valley mouth. Sample chemistry was done at the University of Maine geochemistry laboratory. Processed samples were analyzed on a multicollector ICP-MS at the University of Oxford. Corrected ages reflect a detrital correction based on typical upper-crustal (230Th/232Th) values of 1.21 with a 50% assumed error.
