Subsurface Structure and Mineral Prospectivity of the Wamba Transition Zone, North- Central Nigeria using Airborne Magnetic and Radiometric interpretation

This study utilizes integrated airborne magnetic and radiometric data processing to delineate the subsurface structural controls and mineral prospectivity of the Wamba Transition Zone in North-Central Nigeria, identifying distinct northern gold/rare-metal and southern uranium/phosphate targets associated with Pan-African shear zones and Cretaceous reactivation.

Lineament-Density-Guided Vertical Electrical Sounding for Geoelectric Characterization and Groundwater Potential Mapping of a Basement Complex Terrain, Southwestern Nigeria

This study demonstrates that integrating lineament-density mapping from remote sensing and aeromagnetic data with Vertical Electrical Sounding (VES) effectively identifies fracture-enhanced groundwater potential and validates structural favorability models in the Precambrian basement complex of southwestern Nigeria, offering a reliable strategy for siting boreholes in areas previously plagued by low yields.

GIS-Integrated Plant–Sediment Assessment of Trace-Element Partitioning and FTIR Functional-Group Signatures in Al-Chibayish Marshes, Southern Iraq

This study integrates GIS-derived environmental context with laboratory geochemical and FTIR analyses to characterize trace-element partitioning and organic functional-group signatures among aquatic plants and sediments in Iraq's Al-Chibayish Marshes, revealing distinct retention patterns across biotic and abiotic compartments.

MANUSCRIPT Mapping Rare Earth Element Prospectivity in the Ruri Carbonatite Complex Using Explainable Ensemble Learning

This study develops an explainable stacked ensemble machine learning framework combining SVM, Random Forest, and XGBoost to map Rare Earth Element prospectivity in Kenya's Ruri Carbonatite Complex, achieving 95.6% accuracy and identifying key geological and geochemical predictors through SHAP analysis.

Global distribution and spatial concentration of deep-sea ecological vulnerability: implications for seabed governance

This study introduces a spatially explicit Ecological Vulnerability Index to reveal that deep-sea ecological vulnerability is highly concentrated along mid-ocean ridges and is currently misaligned with seabed governance, as conservation areas are significantly underrepresented in high-risk zones compared to extraction contracts.

Red mangrove (Rhizophora mangle) advancing through a saltwater-freshwater ecotone demonstrates a coordinated leaf trait response to environmental resource and stress

This study reveals that as red mangroves (*Rhizophora mangle*) encroach into Florida's freshwater wetlands, their leaf trait variations and resulting ecosystem services are primarily driven by soil phosphorus availability, water depth, and hydroperiod rather than by water salinity.

Beyond the Lease Boundary: Governing Post-lease Operational Risk Territories in Blasting-based Quarry Operations

This study introduces the concept of Post-Lease Operational Risk Territories (PORTs) and proposes an Adaptive Operational Risk Governance (AORG) framework to address the disconnect between fixed legal quarry boundaries and the extended spatial influence of blasting safety, using the Yongwa Limestone Quarry in Ghana as a case study to advocate for governance models that integrate engineering risk data with land administration and spatial planning.

Evaluating the rural environmental sustainability and inner-system synergy in Chinese provinces integrating Three-Rural and Pressure-State-Response frameworks

This study evaluates the spatiotemporal evolution and subsystem coordination of rural environmental sustainability across 31 Chinese provinces from 2006 to 2023 by integrating the "Three Rural Issues" with the Pressure–State–Response framework, revealing marked overall improvements alongside persistent regional imbalances and a shift toward a "bottleneck" stage in system coordination that necessitates differentiated policy strategies.
