The Dry Andes region of Argentina and Chile is characterized by a highly developed periglacial environment. In these arid or semi-arid regions, rock glaciers represent one the main pieces evidence mountain creeping permafrost water reserves in solid state. However, their distribution, degree activity, response to global warming are not yet well understood. this context, work aims show potential Sentinel-1-based interferometric technique (DInSAR) map active at regional level. particular,...

During the last decades, most glaciers have been retreating and losing mass in all high-mountain regions, where permafrost has also undergone warming, degradation, ice loss. In this context, rock glaciers, a visual indication of presence mountain permafrost, gained attention because they host shallow groundwater resources. Hence, could represent contributor for future water supply, especially arid semi-arid areas and/or during dry periods. However, growing body literature, mostly composed...

Abstract This paper presents an analysis of the internal structure, hydrogeology and dynamics a large, complex, multilobate multiroot rock glacier combining electrical resistivity tomography (ERT), hydrochemical data differential interferometry synthetic aperture radar (DInSAR). The consists series overlapping lobes that represent different advancing stages with degrees conservation. ERT surveys characterize active layer upper part permafrost layer, latter showing heterogeneous geometry...

Rock glaciers (RGs) provide significant water resources in mountain areas under climate change. Recent research has highlighted high concentrations of solutes including trace elements RG-fed waters, with negative implications on quality. Yet, sparse studies from a few locations hinder conclusions about the main drivers solute export RGs. Here, an unprecedented effort, we collected published and unpublished data rock glacier hydrochemistry around globe. We considered 201 RG springs ranges...

Abstract. This paper presents a detailed rock glacier inventory used in determining how the various natural parameters affect mountain periglacial environment. study was undertaken northernmost sector of central Argentine Andes, an area stretching between 31°02' and 31°22' S latitude. is high arid subtropical region where permafrost cryogenic processes are predominant, featuring as well large number glaciers associated landforms. Rock based on geomorphological characterization with optical...

Rock glaciers and protalus ramparts are two of the main morphological features Central Andes in Province San Juan, Argentina. This sector has one highest densities occurrence rock world. In this region, which semiarid climatic characteristics, presence these landforms is important due to their solid state water reserves as resource regulators. Their vital several basins where, lack glaciers, debris-covered perennial snow patches, only solid-state reserves. However, topo-climatic factors...

Las glaciaciones cuaternarias han dejado registro en diversos espacios geográficos de la corteza terrestre. Esto no ha sido una excepción los Andes Centrales Argentina y Chile, donde enormes valles labrados por erosión glacial depósitos morrénicos evidencian el fenómeno. Sin embargo, aún se logrado establecer a nivel regional alcance geográfico éstas glaciaciones, ni volúmenes agua que fueron descargados durante retroceso glaciares. En éste trabajo presenta un mapa geomorfológico temática...

This paper presents a detailed rock glacier and protalus rampart inventory from Las Salinas river basin, an arid subtropical mountain hydrological system (between 31°02’ 31°22’ S latitude) located in the northern sector of Central Andes Argentina, where permafrost cryogenic processes prevail. The is based on geomorphological characterization by means optical remote sensing field description data. study region covers 630 km2, with 3.25% area containing 405±8.2 glaciers ramparts total, which...
