Geological Journal, EarlyView.This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Geo-neutrinos: a new probe of Earth's interior
, 2005 In preparation to the experimental results which will be available in the future, we study geo-neutrino production for different models of mantle convection and composition.

Injection of CO2-saturated brine in geological reservoir: a way to enhanced storage safety [PDF]
, 2016 Injection of free-phase supercritical CO2 into deep geological reservoirs is associated with risk of considerable return flows towards the land surface due to the buoyancy of CO2, which is lighter than the resident brine in the reservoir.

Geological Journal, EarlyView.Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Cement-rock interaction : infiltration of a high-pH solution into a fractured granite core [PDF]
, 2010 Within the framework of the HPF project (Hyperalkaline Plume in Fractured Rock) at the Grimsel Test Site (Switzerland), a small scale core infiltration experiment was performed at the University of Bern.

, 1983 The mathematical formulation· of a one-dimensional, finite-difference compositional simulator is given in this work. The model assumes thermodynamic equilibrium between flowing electrolyte solutions and stationary mineral assemblages, and solves for the mineral identities and compositions and aqueous compositions as a function of both time and position.

Cap rock efficiency of geothermal systems in fold-and-thrust belts: Evidence from paleo-thermal and structural analyses in Rosario de La Frontera geothermal area (NW Argentina) [PDF]
, 2016 Cap rock characterization of geothermal systems is often neglected despite fracturing may reduce its efficiency and favours fluid migration. We investigated the siliciclastic cap rock of Rosario de La Frontera geothermal system (NW Argentina) in order to

Models of Geochemical Speciation: Structure and Applications
, 2018 Being able to predict the behavior of trace elements in the environment is crucial for environmental risk assessment studies. For this reason, modeling, in addition to experimental methods, has become an indispensable tool to better understand the (bio)-geochemistry of trace elements and the processes involved in their availability, transport and ...
