AbstractThis dataset comprises the total and the acid nitric soluble element concentrations of major and trace elements (Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, P, LOI, As, Ba, Be, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Ga, Gd, Ge, Hf, Ho, La, Li, Lu, Mo, Nd, Ni, Pb, Pr, Rb, Sb, Sc, Sm, Sn, Sr, Tb, Th, Tm, U, V, Y, Yb, Zn, Zr) in stream sediments of the Garonne River watershed in the Val d'Aran in the Central Pyrenees. We used samples collected in 1981 in a pilot project of stream sediment geochemistry. The results of nitric acid leachates are used as proxies of the environmentally available fraction of such elements. The samples represents the lithogeochemical units consisting of the Maladeta-Marimanya granitoids, and the metasediments occurring in an extensive area of the basin.
Description1) For whole rock: sieved <180 µm size fraction, pulverized in a vibrating cup laboratory mill, 0.1 g sample digested in HNO3:HClO4:HF (2.5:2.5:5.0, v/v), doubly evaporated to incipient dryness, addition 1 mL HNO3, and made up to 100 mL with Milli-Q Plus ultrapure water type (18.2 MΩ/cm) ; 2) For nitric acid leaching: 0.1 g sample mixed with 1 mL de HNO3 in 12×100-mm polypropylene test tubes In batch experiments, and made up to 100 mL with Milli-Q Plus ultrapure water type (18.2 MΩ/cm). Final solutions were analysed by HR-ICP-MS. Contact person: Fernandez-Turiel, J. L., jlfernandez@ictja.csic.es
