“…The construction rates (Figure c), varied by almost a factor of 15 during the lifetime of the volcano, from 0.04 km 3 /kyr, in early subaerial stages, up to 0.52 km 3 /kyr for the edifice that grew after the second flank collapse. These rates are the same order of magnitude as eruption rates calculated for arc volcanoes in continental or intraoceanic settings [ Frey et al , ; Germa et al , ; Harford et al , ; Hildreth et al , , ; Hora et al , ; Jicha and Singer , ; Lahitte et al , ; Ownby et al , ; Ricci et al , ] and more specifically, for volcanoes from the Lesser Antilles, such as Morne Jacob in Martinique [ Germa et al , ], Soufriere Hills at Montserrat [ Harford et al , ], and Grande Découverte and Piton de Bouillante in Guadeloupe [ Lahitte et al , ; Ricci et al , ]. The total production along the Lesser Antilles during the last 100 kyr has been estimated at 285 km 3 [ Crisp , ] at a rate of 3 km 3 /kyr [ Wadge and Shepherd , ].…”

“…Bulk rock constructional or destructional volumes are obtained by calculating the elevation difference of two successive PDEMs. Construction of the PDEMs involves a multistep process, using the ShapeVolc algorithm [ Lahitte et al , ; Lavigne et al , ; Ricci et al , ], described in Appendix A and summarized below with details regarding this particular study.…”

This study presents long-term volumes and construction rates for the Mont Conil-Mont Pelée volcano and rate estimates at which volcanic activity creates relief. An algorithm, ShapeVolc, is used to numerically model topographic surfaces. Volcano morphology is analyzed using current digital elevation model in combination with mapped geology to produce 10 paleotopographies at the end of four constructional stages and three destructional events. , and 3.5 km 3 , thus about 37% of the total constructed volume. Integrated over the volcano's lifetime, the rate at which flank collapses removed material off the island is 0.15 km 3 /kyr. In contrast, long-term erosion rates outside collapsed areas are estimated at about 0.05 ± 0.7 km 3 /kyr, or~11 km 3 of material removed. This latter rate is not negligible, which strengthens the importance of taking into account recurrent small erosional events on the geomorphological evolution of a volcanic island in a tropical context.

“…This limit is difficult to determine because exposure of outcrops is limited in northern Basse-Terre. Moreover, near the coastline, the attribution of the Deshaies eroded dome (so called "Gros Morne") either to the Basal Complex or to the Northern Chain remains a topic of debate (Samper et al, 2007;Mathieu, 2010;Gailler et al, 2013;Ricci et al, 2015a;Barnoud et al, 2017;Verati et al, 2018;Fig. 1B).…”

In order to decipher the tectono-metamorphic evolution of shallow crustal levels of the active volcanic arc of the Guadeloupe archipelago (Lesser Antilles) we present new geochemical, geochronological, mineralogical and structural investigations of the so-called Basal Complex, the oldest and most eroded volcanic complex of Basse-Terre in Guadeloupe. Based on geochemical and mineralogical criteria we propose an updated geological map of this northern area of Basse-Terre. Using 40 Ar-39 Ar geochronology we demonstrate first that the eroded "Gros Morne" of Deshaies belong to the Basal Complex, and second that this complex is characterized by 4.3 to 2 Ma old volcanism. Structural analysis reveals a long-lived deformation history with the development through time of N80-N100 schistose zones; N110-N140 and N160-N10 oriented hydrothermal breccias and N140-N150 brittle normal faults. The boundary between the Basal Complex and the southernmost Septentrional Chain corresponds to a series of faults with N 150°and N 50°main directions. Detailed mineralogical and petrological investigations, including thermodynamic modeling, allow the identification of three phases of post-magmatic mineralogical transformations with first a high-temperature stage under Greenschist to sub-Greenschist facies conditions (0.6-2 kbar for 250-300°C), a re-equilibration under Zeolite facies conditions and finally a sub-surface alteration. The consistency between P-T conditions of metamorphism and the present day measured geothermal gradient demonstrates that the metamorphic pattern is the record of hydrothermal fluids circulation during building and cooling of the Lesser Antilles magmatic arc. The tectono-metamorphic evolution recognized in the Basal Complex enables us to propose a conceptual model for heat and fluid transport within shallow crustal levels of the Guadeloupe active volcanic arc.Keywords: arc-related metamorphism / Lesser Antilles / Guadeloupe / Basal Complex / tectono-metamorphic evolution / hydrothermal fluids Résumé -Évolution tectono-métamorphique des niveaux superficiels de la croûte dans les arcs volcaniques actifs.

Afin de décrypter l'évolution tectono-métamorphique des niveaux crustaux peu profonds de l'arc volcanique actif de l'archipel de la Guadeloupe (Petites Antilles), nous présentons de nouvelles investigations géochimiques, géochronologiques, minéralogiques et structurales du Complexe Basal, le plus ancien et le plus érodé des complexes volcaniques de Basse-Terre en Guadeloupe. Sur la base de critères géochimiques et minéralogiques, nous proposons une carte géologique actualisée de cette zone nord de la Basse-Terre.
