Genesis of an atypical Podzol in the Iberian Range: micromorphological characterization

A podzol has been described in the Iberian Range (Moncayo Natural Park), which may represent the southernmost example in Europe. The fact that it occurs at the podzol distribution limit makes its morphology atypical. The aim of this work is to identify the components and formation processes of the s...

description A podzol has been described in the Iberian Range (Moncayo Natural Park), which may represent the southernmost example in Europe. The fact that it occurs at the podzol distribution limit makes its morphology atypical. The aim of this work is to identify the components and formation processes of the soil, and to determine if the processes are active or paleo-processes by a micromorphological approach. The study podzol is located in the top of a northern hillside (30% of slope), at 1600 m altitude on quartzitic sandstones, under Scots pine (Pinus sylvestris) with an udic moisture regime and a frigid temperature regime. We found opaque, orthic iron oxide nodules at the base of the profile (Bhs1), which is related to a current oxidation-reduction process; silt caps are also observed on the coarse elements, pedofeatures evidencing the cryoturbation process, probably also current processes. In the Bhs2 horizon, coatings and micro-laminated clay infillings are identified that are interspersed with fine silts in the holes. Many of these coatings are fragmented and mixed with the basal mass of the soil, indicating that they are paleofeature, possibly prior to the current podzolization.

El hecho de estar en su límite de distribución hace que su morfología sea atípica. El objetivo de este trabajo es identificar los componentes y procesos de formación del suelo, y determinar si los procesos son activos o paleo-procesos, mediante un enfoque micromorfológico. El Podzol de estudio está situado en la cima de una ladera septentrional (30% de pendiente), a 1600 m de altitud sobre areniscas cuarcíticas, bajo pino silvestre (Pinus sylvestris) con un régimen de humedad údico y un régimen de temperatura frígido. Se encuentran nódulos opacos, órticos, de óxidos de hierro en la base del perfil (horizonte Bhs1), lo que está relacionado con un proceso de óxido-reducción actual; también se observan casquetes o cappings de limo en los elementos gruesos, edaforrasgo que evidencia el proceso de crioturbación, probablemente también actual. En el horizonte Bhs2 se identifican revestimientos y rellenos de arcilla microlaminada que se intercalan con limos finos en los poros. Muchos de estos revestimientos están fragmentados y mezclados con la masa basal del suelo, lo que indica que son paleoprocesos, posiblemente anteriores a la podzolización actual.Na Cordilheira Ibérica (Parque Natural do Moncayo) foi descrito um Podzol, o qual pode representar o exemplo mais meridional da Europa. O facto de estar localizado no limite de distribuição dos Podzóis torna a sua morfologia atípica. O objetivo deste trabalho é identificar os componentes e os processos de formação do solo, e determinar se estes são processos ativos ou paleo-processos através de uma abordagem micromorfológica. O podzol estudado está localizado no topo de uma encosta norte (30% de declive), a 1600 m de altitude sobre arenitos quartzíticos, sob pinheiro escocês (Pinus sylvestris) com um regime de humidade údica e um regime de temperatura frígido. Na base do perfil (Bhs1) encontram-se nódulos opacos, órticos, de óxidos de ferro, que estão relacionados com um processo de oxi-redução atual; também se observam capas de limo nos elementos grosseiros, características edafoclimáticas que evidenciam o processo de crioturbação e que serão, provavelmente, também processos atuais. No horizonte Bhs2, identificam-se revestimentos e preenchimentos de argila micro-laminada que se intercalam com limos finos nos poros. Muitos destes revestimentos estão fragmentados e misturados com a massa basal do solo, indicando que são paleo-características, possivelmente anteriores à podzolização atual.Universia2020info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttps://doi.org/10.3232/SJSS.2020.V10.N3.04http://hdl.handle.net/10459.1/70103reponame:Repositori Obert UdL instname:Universitat de Lleida (UdL)InglésReproducció del document publicat a: https://doi.org/10.3232/SJSS.2020.V10.N3.04Spanish Journal of Soil Science, 2020, vol. 10, num. 3, p. 209-216cc-by-nc (c) Fibla Cebrián, Nerea et al., 2020info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc/3.0/es/oai:repositori.udl.cat:10459.1/701032026-06-24T12:42:17Z
