Illite (KI) and chlorite (AI) "crystallinity" indices as a constraint for the evolution of the External Briançonnais Front in Western Ligurian Alps (NW Italy)

Dating shallow thrusts with zircon (U-Th)/He thermochronometry—The shear heating connection

“…1C-2E; Table DR2). The <2 µm 128 fraction of the wall rocks has an illite crystallinity (0.31-0.45 KI, in agreement with data reported 129 by Piana et al, 2014) that fall in the late diagenetic/low anchizone conditions (150-250°C, 130 Merriman and Frey, 1999) progressively increasing toward the fault zone (Fig. 2E) (Barker and Goldstein, 1990).…”

Geology of the Entracque–Colle di Tenda area (Maritime Alps, NW Italy)

“…The 1:25,000 geological map of the Entracque -Colle di Tenda area provides a representation of the stratigraphic and structural setting of the Meso-Cenozoic sedimentary successions placed at the northeastern side of the Argentera Massif, and it constitutes a complementary document useful to address some specific issues discussed in papers of recent or forthcoming publications (Barale et al, 2013;d'Atri et al, submitted;Piana et al, 2009Piana et al, , 2014, namely…”

“…This document is, thus, the first published detailed map as part of a scientific programme focusing on the revision of the stratigraphic and tectonic setting of a large area encompassing, from NW to SE, the Italian side of the Maritime Alps and the westernmost part of the Ligurian Alps, the main results of which have been recently published (Barale et al, 2013;Bertok, Martire, Perotti, d'Atri, & Piana, 2011d'Atri, Piana, Barale, Bertok, & Martire, submitted;Martire, Bertok, d'Atri, Perotti, & Piana, 2014;Perotti et al, 2012;Piana et al, 2009Piana et al, , 2014.…”

The Meso–Cenozoic stratigraphic succession of the Col de Braus area (Maritime Alps, SE France)

“…This domain, showing NNW-SSE to N-S fold trends, has been the target of detailed geological survey over the last 15 years by a research group of the Italian National Research Council (Istituto di Geoscienze e Georisorse) and Torino University (Earth Science Department). The related results have been only partly published (d 'Atri et al, submitted;Piana et al, 2014). The Col de Braus area is located at the western termination of this domain and will therefore be important in the definition of its western boundary, which is possibly identifiable in the Rocca Serra-Ongrand Thrust (ROT; Guardia, Ivaldi, Dubar, Guglielmi, & Perez, 1996).…”

“…The Nice Arc shows variably orientated folds and thrusts, trending NNW-SSE in the western part and E-W to NE-SW in the southern and southeastern part (Bulard et al, 1975;Gèze, 1963;Perez, 1975). The Roya Arc is the westernmost part of a larger structural domain (RoyaArgentina Unit; d 'Atri, Piana, Barale, Bertok, & Martire, submitted;Piana et al, 2014), extending from the westernmost Ligurian Alps (Nervia-upper Argentina valleys) to the eastern part of the Maritime Alps and bounded towards the north by the Argentera Massif. This domain, showing NNW-SSE to N-S fold trends, has been the target of detailed geological survey over the last 15 years by a research group of the Italian National Research Council (Istituto di Geoscienze e Georisorse) and Torino University (Earth Science Department).…”
