Pb isotope results of acid-reductive leaching of bulk sediments from the Sorbas and Caltanissetta Basins and the Apennine Foredeep. Uncertainties in the table are internal measurement uncertainties reported to 2 SE. Some samples were repeated; if RPT# is noted, this is a repeated measurement of the same solution. Otherwise, the repeat measurement was performed with a separate leaching of a new portion of sediment. An average value of these measurements is provided where relevant. The analytical session in which the measurement was performed is explained in the table footnote.

Numbers in 'Analysis run' indicate the time when the measuring sessions took place: 1 - August 2013; 2 - February 2014; 3 - November 2014; 4 - September 2015
