Geomorphology of the Maladeta massif (Central Pyrenees): the traces of the last remaining glaciers

Journal of Maps
We present a 1:15,000 geomorphological map of the Maladeta massif in the Central Pyrenees. Our methodology includes fieldwork, the analysis of aerial photographs from 1956 to 2015, and the use of drone flights from 2020 to 2023.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

The Margeride granite massif (French Central Massif)

, 1977
L'étude du Massif granitique de la Margeride (Massif Central français) a été abordée par les méthodes cartographiques, pétrographiques, géochimiques et structurales, adaptées au caractère largement grenu et porphyroïde que présente la quasi-totalité des roches de ce très vaste ensemble.Deux exemples remarquables de différenciation par gravité ont pu ...

The nature of zircon in the Volkovsky massif gabbro (Middle Urals): the age problem and geochronological consequences

Литосфера, 2017
The article presents new isotope-geochemical data on zircon from gabbronorites of the Volkovsky massif in the Middle Urals. The massif is a complex combination of different rock associations - from ultramafic rocks to syenites and quartz diorites, whose ...

Thinning of the Monte Perdido Glacier in the Spanish Pyrenees since 1981 [PDF]

, 2016
Producción CientíficaThis paper analyzes the evolution of the Monte Perdido Glacier, the third largest glacier in the Pyrenees, from 1981 to the present. We assessed the evolution of the glacier's surface area by analysis of aerial photographs from 1981,

Flow‐pattern evolution of the Scandinavian Ice Sheet indicated by the subglacial lineation record over Norway, Sweden and Finland

Boreas, EarlyView.
We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Sedimentary provenance of siliciclastic rocks from the Lalla Mouchaa Calcschists Formation (Coastal Block, Western Rehamna): Evidence of denudation of ca. 2 Ga basement in the Moroccan Meseta. [PDF]

, 2018
Paleoproterozoic basement rocks (ca. 2Ga) are scarce along the European and North African Paleozoic mountain chains (Fig.1a). In Morocco, ca. 2.2-2Ga granitic rocks (Gasquet et al., 2008; Kouyaté et al., 2013) have been exclusively reported in the ...

Paléosurfaces d'altération du Massif central

, 2018
Au sein du Massif central, une majeure partie du relief est caractérisée par des géomorphologies en forme de plaines et plateaux. L'altitude des plateaux est hétérogène, elle peut varier de la centaine de mètres à plus de 1000m. Ces surfaces correspondent à des surfaces d'aplanissement portant des profils d'altération.
