资源简介：
Samples are volcanic ash collected between November 1999 and March 2016 on the flank of Tungurahua volcano (Ecuador). Isotope compositions were measured on 5 mg of juvenile glassy fragments, after sample dissolution and Sr- Pb separation using chromatographic methods. Lead and Sr isotope compositions were measured at Laboratoire Magmas et Volcans (Clermont-Ferrand, France) by MC-ICP-MS and TIMS, respectively.
