Deglaciation history at the Alpine‐Mediterranean transition (Argentera‐Mercantour, SW Alps) from 10Be dating of moraines and glacially polished bedrock

“…The LGM stage is followed by at least two cold periods well expressed in the northern and eastern Alps: the Gschnitz re-advance is dated at 17-16 ka (Maisch, 1992;Ivy-Ochs et al, 2006a, 2006b and the Egesen stadial at 13.0-11.5 ka (Ivy-Ochs et al, 2009;Schindelwig et al, 2012). Rodriguez-Rodriguez et al, 2014;Palacios et al, 2017;Fernández-Fernández et al, 2017). A similar chronology is confirmed in the western Alps (e.g.…”

Surface macro‐fabric analysis of relict rock glaciers in the Cantabrian Mountains (NW Spain)

“…In this sense, as we have seen throughout the text, the data for tongue‐shaped and lobate rock glaciers show significant differences in some aspects, pointing to different origins or, at least, to a greater influence of other processes (snow, gravity) in the lobate rock glaciers. Recently, Fernández‐Fernández et al pointed out that some previously interpreted rock glaciers in the Iberian System were originally debris‐covered glaciers. Although it is possible that there are also similar examples in the Cantabrian Mountains, the absence of fabric data on active forms makes it difficult to use this technique to discriminate them.…”

“…1,7,9,12 In the Iberian Peninsula, rock glaciers have been identified since the 1980s in the main ranges, such as the Pyrenees, [13][14][15][16][17][18] Sierra Nevada [19][20][21] and the Iberian System. 22,23 In the Cantabrian Mountains they have been identified since the end of the 1980s [24][25][26] and prpvide are some of the best examples of relict rock glaciers in the Iberian Peninsula. Studies of the location, distribution and morphometry have been made more recently.…”

Late Pleistocene climate of the northern Iberian Peninsula: New insights from palaeoglaciers at Fuentes Carrionas (Cantabrian Mountains)

“…Only one small cirque glacier developed at the LIA (Gómez‐Ortiz et al , ). Apart from these aforementioned cases and from the Cantabrian Mountains, only marginal glaciation developed in the Central and South Iberian Peninsula (Fernández‐Fernández et al , ).…”
