Paleosuelos en secuencias coluvio-aluviales del Pleistoceno – Holoceno en Tlaxcala: registros paleoambientales del poblamiento temprano en el centro de México

Abstract: Paleosuelos del Cuaternario tardío en Tlaxcala como registros paleoambientales 91 ResumenEl estudio de paleosuelos cobra importancia al considerar la posición que ocupan en el paisaje, ya que representan un continuo que cambia en función de la geoforma y constituyendo una toposecuencia. En este contexto, aquí se muestran los resultados de tres secciones paleopedológicas localizadas en el Bloque Tlaxcala y los efectos de la pedogénesis dependiendo de su posición en el paisaje, de las condiciones ambientales y d… Show more

“…In the case of the RU, the weathering degree, the presence of Fe-clay coatings (Sedov et al, 2009), the high Fed content, the absence of volcanic glass, and the low amount of allophane (Table 3), are interpreted to have formed in humid e warm conditions. In the GU, the lower weathering degree, Fed content, and clay coatings, which are impregnated with humus (Solís-Castillo et al, 2012), are related to humid but cooler environments.…”

“…5). It is formed by four palaeosols, designated as TX1, TX1a, TX1b, and TX2 which cover MIS 2 and 3 (Sedov et al, 2009;Solís-Castillo et al, 2012), where TX1 and TX2 are the best developed and consist of greyic Luvisols. They show argic horizons and greyish colors but there is no analytical information about the base saturation.…”

“…The studied sequence consists of seven pedostratigraphic units separated by ash layers. It is subdivided in four main layers based on morphologic characteristics: a modern soil, the Gray, the Brown and the Red Units, from top to bottom with a total depth of 1528 cm (Figure 2) (for more details see Rivas et al, 2006;Sedov et al, 2009;Solis-Castillo et al, 2012).…”

“…"La Barranca de Tlalpan" sequence was first investigated for paleoenvironmental purpose (Ortega-Guerrero et al, 2004;Sedov et al, 2009;Solis-Castillo et al, 2012), but some few oriented hand samples at the lower part yielded stable, reverse polarity magnetization. This fact was the main motivation to revisit and sample the whole sequence in greater details.…”
