Analytical techniques included petrographic analysis of gravel-sized clasts, geochronology Supporting Information: (zircon U-Pb: Zrn-UPb) and thermochronology (apatite fission track: AFT) of sand-sized fractions. Supporting Information S1 Petrographic analysis revealed a similarity with the lithologies presently exposed in western Marie Byrd Land (MBL), with major roles played by low-grade metamorphic rocks and granitoids. Furthermore Zrn-UPb Correspondence to: and AFT data allowed to identify the ages of formation and cooling of sedimentary source area, consisting M. Perotti, of Cambrian-Precambrian basement (i.e., Swanson Formation in western MBL) which underwent at least
