Public ISBD Faire une suggestion d'achat Titre : 210 Pb-derived ages for the reconstruction of terrestrial contaminant histo into the Mexican Pacific coast : potential and limitations Type de document : texte imprimé Auteurs : Ruiz-Fernandez, A.C., Auteur Importance : pp. 134-145 Langues : Anglais (eng) Index. décimale : 577 Ecologie Résumé : 210 Pb is widely used for dating recent sediments in the aquatic environment; howeve working in shallow coastal environments in the Pacific coast of Mexico have demc potential of 210Pb for reliable historical reconstructions might be limited by the low; fallout, sediment mixing, abundance of coarse sediments and the lack of 137Cs signal fo tion. This work discusses the difficulties in obtaining adequate sedimentary records foi reconstruction in such active and complex settings, including examples of 2l°Pbgeoc on sediment profiles collected in two contrasting areas coastal areas (mudflats m lagoons of Sinaloa State and the continental shelf of the Gulf of Tehuantepec), in which was used to support the temporal frame established and the changes in sediment supf sediment cores which were related to the development of land-based activities during the last century. 210 Pb-derived ages for the reconstruction of terrestrial contaminant histo into the Mexican Pacific coast : potential and limitations [texte imprimé] / Ruiz-Fernandez, A.C., Auteur . - [s.d.] . - pp. 134-145.
