U-Pb (Uranium-Lead) geochronology data for carbonates from the Nequen Basin Argentina. Data was collected for a series of Copper (Cu) deposits: Los Chihuidos, Barda González, La Cuprosa, El Porvenir and Tordillos Cu deposits. The Los Chihuidos deposit contains calcite either as individual calcite grains or as sparry, calcite cement in a red calcareous sandstone. The Barda Gonzales samples were recovered from a well sorted sandstone. The calcareous litharenite from the Huincul Formation at El Porvenir is well-sorted, texturally, and compositionally mature. Calcareous sandstones from the Tordillos Deposit contain calcite as fibro-radial calcites amongst a wider, poikilotopic calcite matrix. Context of samples and methods described in; Chapter 6.
