U-Pb-Hf zircon data from Wilkes/Queen Mary landsThis dataset file is unpublished. Details of analytical methods: U-Pb from Daczko et al. (2018) and Lu-Hf from Halpin et al. (2020). U-Pb analysis was via SHRIMP following procedure outlined in Daczko et al. (2018). Zircon grains were hand-picked and mounted into a 25-mm diameter epoxy resin disc along with grains of reference zircons BR266 (559 Ma, 909 ppm U; Stern and Amelin, 2003) and OGC-1 (34

U-Pb data from detrital zircons extracted from till and rocks samples from the eastern Weddell Sea EmbaymentThis dataset is from detrital zircons extracted from moraine tills and erratic pebbles and bedrock exposed along the Foundation, Academy and Recovery Glaciers in the Weddell Sea Embayment, as well as from cores from the margin of the Ronne and Filchner Ice Shelves. It includes a total more than 5000 U-Pb ages. Most of the tills are Holocene-LGM, some are as old as 2 Ma. Erratics and bedrock sample

Provenance data from Quaternary tills in the Transantarctic MountainsTwo high-elevation moraines sequences in the southern-central Transantarctic Mountains were sampled to characterize provenance changes through time. Samples were collected in transects across the moraine system at the base of Mt. Achernar, at the head of the Law Glacier and at Mt. Howe, at the head of Scott Glacier. Till samples were analyzed for particle size, pebble petrography, quantitative x-r
