Short summary
Clay minerals are helpful markers of low-temperature geological processes. The combination of their characterization with geochronology is a powerful tool to constrain physical and chemical processes, improving our understanding of the evolution of the Earth system. This paper aims to present the platform along with the associated methods developed at the GeoRessources laboratory (University of Lorraine) to separate, characterize clay minerals and date illites using the K-Ar method.

The present study is based on sample chemical and mineralogical analyses of oceanic sediment and rock that were collected in the Guaymas Basin during IODP Expedition 385. The contact aureoles are not only affected by maturation of organic matter and dehydration reaction, but mineralogical reactions concern all sediment components (silicates, sulfides, carbonates, organic matter) and can be the result of the combination of different stages of alteration during and after the sill emplacement.

Short summary
This study improves geochemical mapping by addressing the uncertainty in defining element associations. It clusters the study area by element similarity, recognizes elemental associations for each cluster, and then detects anomalies indicating underlying geological processes. This method is applied to a region in China, confirming its effectiveness and consistency with the geology. This study can enhance geochemical mapping for mineral exploration and improve geological-process understanding.

The Basal Complex unit on Fuerteventura island comprises magmatic rocks showing significant rare Earth element (REE) concentrations with values up to 10 300 ppm REY (REEs plus yttrium). We carried out mineralogical and geochemical analyses, but additional research is needed to fully understand their distribution due to structural complexities and environmental factors.

The Taodonggou Group mudstone was deposited in a warm, humid, and hot paleoclimate with strong weathering. The parent rocks of the Taodonggou Group mudstone are felsic volcanic rocks and andesites, with weak sedimentary sorting and recycling and with well-preserved source information. The Taodonggou Group mudstone was deposited in dyoxic fresh water–brackish water in intermediate-depth or deep lakes with stable inputs of terrigenous debris but at slower deposition rates.

Orogenic gold deposits in Paleoproterozoic belts in northern Finland have been explored not only for gold but because of the occurrences of economically important concentrations of base metals, especially cobalt. In this study we are testing the vectoring capacities of pyrite trace element geochemistry, combined with lithogeochemical and sulfur isotopic data in the Raja gold–cobalt prospect (northern Finland), by using multivariate statistical data analysis.

The Hurricane fault is a major and active normal fault located in the southwestern USA. This study utilizes the geochemistry and dating of calcite veins associated with the fault to characterize ancient groundwater flow. Results show that waters moving along the fault over the last 540 000 years were a mixture of infiltrating fresh water and deep, warm salty groundwater. The formation of calcite veins may be related to ancient earthquakes, and the fault influences regional groundwater flow.

Short summary
To understand the fate of carbon in subducted oceanic sediments and crust, we studied carbonate phases in rocks from the Mariana subduction zone. These show that carbon is liberated from the downgoing plate at depths less than 20 km. Some of the carbon is subsequently trapped in minerals and likely subducts to greater depths, whereas fluids carry the other part back into the ocean. Our findings imply that shallow subduction zone processes may play an important role in the deep carbon cycle.

Short summary
Sediments containing hydrates dispersed in the pore space show a characteristic seismic anomaly: a high attenuation along with increasing seismic velocities. Recent major findings from synchrotron experiments revealed the systematic presence of thin water films between quartz and gas hydrate. Our numerical studies support earlier speculation that squirt flow causes high attenuation at seismic frequencies but are based on a conceptual model different to those previously considered.

Short summary
Understanding the fluid circulation in fault zones is essential to characterize the thermochemical evolution of hydrothermal systems in mountain ranges. The study focused on a paleo-system of the Pyrenees. Phyllosilicates permit us to constrain the evolution of temperature and redox of fluids at the scale of the fault system. A scenario is proposed and involves the circulation of a single highly reducing hydrothermal fluid (~300 °C) that evolves due to redox reactions.
Understanding the fluid circulation in fault zones is essential to characterize the...
