Use of cold waters geochemistry as a geothermal prospecting tool for hidden hydrothermal systems in Réunion Island

Communications Earth & Environment (2024)

Bhavani Bénard Vincent Famin Pierre Agrinier Pascale Louvat Geneviève Lebeau

Abstract Most untapped high-enthalpy geothermal resources are blind, meaning lacking surface evidence of their existence. The first step in their discovery is to find evidence of hydrothermal activity. Here we apply an approach based on the geochemistry of cold waters, which allowed us to identify evidence of the existence of a hydrothermal system at Piton de la Fournaise volcano (Réunion Island), and constrain its location. This approach uses the concentrations in B, Li, SO 4 , F, Mo, P, V, As and HCO 3 and the isotopic ratios δ 13 C and δ 11 B as geochemical markers of hydrothermal activity that can be used even in waters with extremely low ion content (Electrical conductivity <80 µS/cm), and even when their geochemical composition is mainly controlled by other processes. This noninvasive approach is easy to implement and can be applied wherever the presence of a blind geothermal system is suspected.

Changes in the geometry and strength of the Atlantic Meridional Overturning Circulation during the last glacial (20–50 ka)

Pierre Bürckel Claire Waelbroeck Yiming Luo Didier M. Roche Sylvain Pichat

Abstract. We reconstruct the geometry and strength of the Atlantic Meridional Overturning Circulation during Heinrich Stadial 2 and three Greenland interstadials of the 20–50 ka period based on the comparison of new and published sedimentary 231Pa/230Th data with simulated sedimentary 231Pa/230Th. We show that the deep Atlantic circulation during these interstadials was very different from that of the Holocene. Northern-sourced waters likely circulated above 2500 m depth, with a flow rate lower than that of the present day North Atlantic Deep Water (NADW). Southern-sourced deep waters most probably flowed northwards below 4000 m depth into the North Atlantic basin, and then southwards as a return flow between 2500 and 4000 m depth. The flow rate of this southern-sourced deep water was likely larger than that of the modern Antarctic Bottom Water (AABW). At the onset of Heinrich Stadial 2, the structure of the AMOC significantly changed. The deep Atlantic was probably directly affected by a southern sourced water mass below 2500 m depth, while a slow southward flowing water mass originating from the North Atlantic likely influenced depths between 1500 and 2500 m down to the equator.

Roman Builders Facing the Risk of Disaster: Coupling Archaeological and Geochemical Analyses on a Section of the ‘Aqua Augusta’ (the Roman Serino Aqueduct, Southern Italy)

Archaeometry (2018)

Francesca Filocamo Julie Carlut Hélène Dessales Pierre Bürckel Stephan Borensztajn

Four samples of carbonate sinters from two sites of the Roman Serino aqueduct were studied in order to better constrain the history of the aqueduct and to estimate to what extent natural hazards can be recorded in such deposits. Micromorphological observations, trace element, stable oxygen and carbon isotope analyses were performed on the samples. Together with new quantitative observations on the construction techniques of the aqueduct, our results highlight the imprint left by geological hazards on the Serino aqueduct. Damage, disruption, ground movement and a debris‐flow are evidenced.
