Abstract. Water infiltration and recharge processes in karst systems are complex difficult to measure with conventional hydrological methods. In particular, temporarily saturated groundwater reservoirs hosted the vadose zone can play a buffering role water infiltration. This results from pronounced porosity permeability contrasts created by local karstification of carbonate rocks.

Fieldwork is a key learning component of geoscience training and education, providing students with hands-on experience deeper understanding concepts plus 3D spatial awareness complex geological structures. Research shows that extended field trips significantly enhance these skills compared to lab- or theory-based activities alone. However, taking all world-class outcrops fascinating sites unfeasible due cost, logistical challenges, environmental concerns, restrictions during pandemic...
Zircon geochemistry provides critical information on the melt from which they form. Specifically, Eu and Ce anomalies in zircons can be used to infer evolution of average crustal thickness over time. However, are typically influenced by multiple factors, such as depth magmagenetic processes, nature parental magma, magma hydration, oxidation state, crystallization minerals like plagioclase, apatite, garnet. As a result, translating these data into paleo-depth is challenging introduce...
The resurgence of Banded Iron Formations (BIFs) during the Neoproterozoic, following a billion-year hiatus, reflects significant geodynamic and climatic transition. Newly discovered Neoproterozoic BIFs in central Anti-Atlas region Morocco provide key insights into these processes. studied units are exposed within Bou Azzer-El Graara inlier (Central Anti-Atlas), an oceanic paleo-suture zone between Paleoproterozoic West African Craton remnants magmatic arc. This comprises 750 to 680 Ma arcs...
Spatial understanding of complex geological structures is a fundamental component geoscience expertise. However, when teaching mapping, students often face challenges in grasping 3D concepts through ‘traditional’ 2D or projected materials, such as maps and cross-sections. In this perspective, we developed specialized course for Master's the Geosciences program at Lyon (https://lyongeologie.fr/m1-geosciences/), using Visual KARSYS app (https://www.visualkarsys.com/).Visual...
The evolution of the seawater oxygen isotopic composition (δ18O) through geological time remains controversial. Yet, past δ18Oseawater is key to assess temperatures, providing insights into climate change and life evolution. Here we provide a new unprecedentedly precise δ18O value -1.33 ± 0.98‰ for Neoproterozoic bottom supporting constant isotope time. We demonstrate that Aït Ahmane ultramafic unit ca. 760 Ma Bou Azzer ophiolite (Morocco) host fossil black smoker-type hydrothermal system....
Trace elements in zircon are a promising proxy with which to quantitatively study Earth’s long-term lithospheric processes and its geodynamic regimes. The Eu anomaly reflects the crystallization environment of felsic or intermediate parental magma. In particular, it provides insight into water content, magmatic redox conditions, extent plagioclase fractionation source rock occurrence as cogenetic crystallizing phase from We performed statistical analysis anomalies compilation detrital...
ABSTRACT Thick-crusted (>45 km) Cordilleran arcs exhibit cyclic processes including periods of magmatic quiescence interspersed with pulses high-flux magmatism. Most models assume that during events, fractional crystallization and partial melting within the deep crustal hot zone generate a dense (>3.4 g/cm3) arclogitic subarc root can readily founder into mantle. Yet these do not consider that: (1) retention low-density melt root, (2) protolith lithology restitic portion may...
Abstract The Santa Catalina‐Tortolita‐Rincon Mountains of Southeast Arizona are a classic metamorphic core complex (MCC) and represent footwall exposures crustal rocks exhumed by detachment system.
