Table 2 - MCICPMS Pb isotope compositions bulk marginal sediment leachates

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.
