The analyses of Lanaittu Sandstone (Campanian, Eastern Sardinia, Italy), recovered in a geognostic well in eastern Sardinia permit the reconstruction of the paleogeography of this area. This report contains petrographic, geo-, and thermochronologic data from arenites. In particular, Table S1 comprises main composition data, lithic content and heavy mineral association. In Tables S2 and S3 are reported the geo- and thermochronologic data of the two zircon samples analysed. The Lanaittu Sandstone reveal an arkosic or arkosic-lithic composition, indicating provenance straddling the fields of the transitional continent and recycled orogen.Lithic fragments consist predominantly of plutonic, gneissic, and low-grade metamorphic rocks with rare carbonates and other sedimentary components. The heavy mineral assemblage includes rare glaucophane-crossite combined, up to 13% kyanite, and trace amounts of lawsonite, indicating an HP-LT metamorphic source. U-Pb and (U-Th)/He dating of detrital zircons records cooling in the source region, with a minor but significant mid-Cretaceous population (22%) reflecting exhumation-related cooling. Older zircon (U-Th)/He age populations indicate a contribution from upper-crustal rocks that mostly record Paleozoic cooling.
