Geoquímica del yacimiento Pb-Zn-Ba-(Hg) de Argallón, Picos de Europa, Asturias (España)

Abstract

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
