The samples were cored along a geognostic borehole in the Lanaittu valley in eastern Sardinia. We combine zircon U-Pb geochronology with (U-Th)/He thermochronology to determine the time of grain formation and cooling through the upper crust. Together, these data provide a more powerful provenance signal than each of these methods alone. The two samples consist of detrital zircon U-Pb dates that are Permian and older, and show no significant differences between them. The acceptable U-Pb dates range from 223 ± 8 Ma (2σ) to 2490 ± 42 Ma and are much older than the middle-late Campanian depositional age of the dated samples. The detrital zircon U-Pb date distributions are consistent with a provenance from the Sardinia block or from the continental crust of an Alkapeca continental fragment, such as a Calabrian terrane/subterrane, or from both sources. The detrital zircon (U-Th)/He dates are also all older than the depositional age of the sandstones. Their distribution is continuous and rather simple with most dates (78 %) being Paleozoic to Jurassic forming a population centered around 261 ± 5 Ma, while the remaining dates (22%) form a population centered at 100 ± 4 Ma. The detrital zircon (U-Th)/He dates suggest a source area exposing rocks with heterogeneous thermal histories—some having experienced rapid cooling during the Cretaceous, and most others resided in the upper crust since the Paleozoic–early Mesozoic.9.501440.2592Eastern SardiniaNatural Sciences and Engineering Research Councilhttps://doi.org/10.13039/50110000003803863RGPIN-2024
