RT Journal Article T1 Geoquímica del yacimiento Pb-Zn-Ba-(Hg) de Argallón, Picos de Europa, Asturias (España) T1 Geochemistry in the Argallón Pb-Zn-Ba-(Hg) deposit. The Picos de Europa, Asturias (Spain) A1 Bravo, J. I. A1 Fernández, C. J. AB In the mining area of Argallon, located in the northern region of the «Picos of Europa» (eastern Asturias), 82 samples of host rock have been analysed, 25 correspondins to siliceous materials-silidfication masses of hidrothermal alteration and levels of quarzitic sandstones-, and the rest corresponding to carbonate materials. Analysis for spectrometry of atomic absorption of the elements Pb, Zn, Ba, Hg, Fe, Mn and Cu have been made, with the purpose of finding on the degree of dispersion. The results obtained shown that this Pb-Zn deposit in carbonate rocks is epigenetic PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/12338 UL http://hdl.handle.net/10272/12338 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
