Las simas del Macizo Occidental de los Picos de Europa: disposición estructural, depósitos asociados y características del drenaje

Abstract

Se estudia de manera especial la morfología y organización interna de las grandes simas, algunas con más de 1.000 m de desarrollo vertical, su relación con la evolución general del macizo, el tipo de relleno sedimentario que contienen, las particularidades del drenaje y las principales surgencias que alimentan.

Ground and Near-Rock Surface Air Thermal Regimes in the High Mountain of the Picos De Europa (Cantabrian Mountains, NW Spain)

“…This soil thermal pattern, made up of four main phases, has also been identified in other high mountain sectors of the Cantabrian Mountains (Central Massif of the Picos de Europa, Ubiñas Massif, Fuentes Carrionas) in several specific studies (Gallinar-Cañedo et al, 2022b;González-Trueba, 2007;Pellitero, 2012;Pisabarro et al, 2015Pisabarro et al, , 2017Ruiz-Fernández et al, 2014. In other Iberian mountain sectors, such as the Corral del Veleta area (Sierra Nevada), Salvador-Franch et al ( 2010) described a similar soil thermal pattern.…”

“…Therefore, the cryonival belt is a very dynamic environment, although with a very small extension, since many peaks of the massif exceed 2,200 m in altitude, but very few reach or exceed 2,400 m. In addition, there are very few deposits in these levels, since they are very abrupt areas dominated by vertical rocky walls. In addition to the Picos de Europa (Brosche, 1978;Castañón & Frochoso, 1998;González-Trueba, 2007;Ruiz-Fernández et al, 2014;, the cryonival belt is present mainly in other sectors of the Cantabrian Mountains such as the Fuentes Carrionas Massif (Pellitero, 2012) and the Ubiñas Massif (Gallinar-Cañedo et al, 2022a).…”

“…In the Cantabrian Mountains, in the last decades significant progress has been made in the knowledge of the active periglacial dynamics of the highest areas (e.g. Castañón & Frochoso, 1994, 1998Gallinar-Cañedo et al, 2022a;González-Gutiérrez, 2002;González-Trueba, 2007;Pellitero, 2012;Ruiz-Fernández et al, 2014;Sanjosé-Blasco et al, 2020;Santos-González, 2010;Serrano et al, 2019a). Likewise, studies have multiplied on the climatic conditions that favor periglacial morphodynamics: changes in the soil thermal pattern throughout the year, the snow cover duration (SCD), the number of days and/or freeze-thaw cycles (FTC), and the influence of soil granulometry, air temperature, wind and solar radiation.…”

Postglacial Landscape Changes and Cryogenic Processes in the Picos de Europa (Northern Spain) Reconstructed from Geomorphological Mapping and Microstructures on Quartz Grains

“…The study area has been intensively shaped by Quaternary glaciers (Alonso, ; Marquínez and Adrados, ; González‐Trueba, , ; González‐Trueba and Serrano, ; González‐Trueba et al ., , ; Ruiz‐Fernández et al ., , ; Moreno et al ., ; Jiménez et al ., ), karstification (Miotke, ; Santos and Marquínez, ; Ballesteros et al ., , ; Ruiz‐Fernández and Serrano, ; Ruiz‐Fernández and Poblete, ) and fluvial and alluvial processes (Ruiz‐Fernández and Poblete, ). The massif is now entirely deglaciated, although in the highest altitudes of the Western Massif periglacial processes are currently active.…”
