Abstract Assessment of the underground geothermal potential requires knowledge deep temperatures (1–5 km). Here, we present new temperature maps obtained from oil boreholes in French sedimentary basins. Because their origin, data need to be corrected, and local character necessitates spatial interpolation. Previous were 1970s using empirical corrections manual In this study, update number measurements by values collected during last thirty years, correct for transient perturbations carry out...
A microthermometric study using infrared microscopy was performed on fluid inclusions hosted in stibnite crystals of the Brouzils antimony deposit, order to characterize fluids responsible for deposition at end Variscan metallogenic sequence. Primary were moderately saline (3.5–4.75 wt % NaCl equiv) with homogenization temperatures varying between 140° and 160°C. Two generations later are also contained samples. The first generation secondary is found exclusively characterized by low...

Abstract Deep temperature estimates previously made in France show three main positive thermal anomalies, one of them being centred on the Provence basin (southeast France) between Marseille and Montpellier. This study presents newly corrected data improved maps order to (i) validate or invalidate anomalies identified (ii) relate deep temperatures with major geological structures area. Although gradient varies from place place, it averages 31.3°C./km (from 30.6 32.5°C/km average for...
Abstract Guadeloupe island (West French Indies) is one of the twenty islands that compose Lesser Antilles arc, which results from subduction Atlantic ocean plate beneath Caribbean one. The lies in a complex volcano-tectonic system and need to understand its geological context has led numerous on- offshore geophysical investigations. This work presents compilation processing available, on-land, airborne marine, gravity magnetic data acquired during last 40 years on at scale arc. overall...
Structural, textural, mineralogic, microthermometric, and isotopic data obtained on the Biards Sb-Au district, located in south Limousin area (Massif Central, France) provide new evidence for tectonic setting of stibnite gold deposition during late orogenic Variscan collapse western Europe. A variety geologic geophysical define a major, crustal-scale, left-lateral strike-slip shear zone that acted as trap mineralization. During these movements, fault-fill veins then extensional limited...
Abstract Mineral separates of adularia have been extracted from three samples highly silicified hydrothermal breccias, newly discovered in the active Bouillante geothermal field (Guadeloupe archipelago), and investigated by 40 Ar/ 39 Ar geochronology order to constrain timing activity this part Lesser Antilles island arc. The inverse isochron diagram indicates an age 248±50 ka (2σ) for all one breccia sample ( n =8), with initial 36 ratio atmospheric composition (309±12 (2σ)) attesting that...
Abstract Surficial indicators of recent to present geothermal activity are around Bouillante (Guadeloupe, French West Indies). Until lately, most mineralogical parageneses identified in this area were typical low temperature alteration (< 100°C) with the occurrence dioctahedral aluminous smectites accompanied by zeolites (heulandite-clinoptilolite) ± calcite silica kaolinite, as an evidence cap rock system. Recently, numerous boulders highly silicified breccias containing high...
