Morfogénesis, procesos y evolución del horizonte Bw cámbico en tefrapaleosuelos del volcán Nevado de Toluca

Abstract: Resumen La presencia de un horizonte Bw cámbico en el perfil de un paleosuelo reviste una importancia particular en las ciencias de la Tierra debido a la información ambiental y cronológica contenida en su memoria. La interpretación de esa información coadyuva a la reconstrucción paleoambiental y paleoclimática de un sitio, indicando, además, la presencia de los diferentes ciclos de estabilidad del paisaje y procesos pedológicos ocurridos durante el desarrollo del horizonte Bw. Particularmente, en este trabajo… Show more

“…As these values decrease, the loss of silica increases. It is assumed that the loss of silica is equal to the total number of lost elements (Jasso-Castañeda et al, 2012). In the current study, the SA values range from 4.19 to 32.17 for hardened horizon, while in surface horizons these varied from 5.27 to 8.07.…”

“…A relevant discovery however paleosols are much less known; in fact most studies concerning them have been conducted within archaeological projects, and pertain mostly to the Late Pleistocene-Holocene [cf. Gama-Castro et al (2005"a"-"b"), McClung et al (2005), Solleiro et al (2006, Rivera-Uria et al (2007), Balcells-González et al (2011), Jasso-Castañeda et al (2012), Pérez-Pérez et al (2012]. Thus, the unquestionable finding of thick relict Luvisols in the badlands developed in the floodplain strata of the Late Miocene San Nicolás Formation, as well as of other kind of paleosols within and on the peneplained deposits of this unit, makes them the oldest paleosols reported -albeit briefly-from this country [cf.…”
