VOLTAIRE (http://labex-voltaire.prod.lamp.cnrs.fr/) unites all the players on the Orléans campus (University of Orléans, CNRS, BRGM and INRA) interested in quantifying the origins, fluxes and impacts of geofluids, sourced from either the mantle or crust, and ultimately their role in the atmosphere, with implications on natural resources of all kinds (ie ore-deposits, geothermal energy, air/soil pollution, and global climate change). Researchers are from Earth and Atmosphere sciences and Economics, totalling 180 persons. Methods implemented include field observations of various types (ie structural geology, the study of ore deposits, measurement of natural gases either at ground level (peatlands, volcanoes), or in the troposphere/stratosphere). These observational data are supplemented by laboratory studies such as experimental simulations (supported by the Equipex PLANEX), radiometric dating, and numerical modelling, to produce predictive scenarios of the observed processes. The economic implications of the exploitation of some of the resources are quantitatively evaluated using approaches and tools developed by economists. VOLTAIRE also includes a prospective tool aimed at anticipating the level of employment in the general field of geosciences. To date, VOLTAIRE has funded 24 PhD (partly or whole) (420 pm), 38 post-docts (557 pm) 60 Master projects (300 pm), 26 engineers (416 pm), 3 summer schools, 13 international workshops. 3 ERC grants have been running under VOLTAIRE umbrella. In 2018, we published 61 papers in peer-reviewed international journals. The 2018 year has been devoted to the definition of main topics of research proposed for the renewal of VOLTAIRE for the period 2020-2024. These will continue to bear on the study of ressources associated to geofluids, tackled principally from in-situ experiments, either in or out-door, building upon the various facilities installed with VOLTAIRE, PLANEX and PIVOTS projects.
