Phased ecological assembly of Triassic marine reptile faunas following the Permian–Triassic mass extinction: ecospace dynamics in South China

The Permian-Triassic mass extinction triggered a fundamental reorganization of marine ecosystems, yet the community-level functional dynamics of early marine reptile radiations remain understudied. Here we quantify ecospace dynamics of Triassic marine reptile faunas across an app...

Dual pathways controlling Mn-carbonate mineralization in redox-stratified basins: Geochemical constraints from the Ortokarnash deposit (Western Kunlun, China)

The formation of sedimentary manganese deposits—vital sources of a critical metal for green technologies—is intimately linked to redox-stratified basins, yet whether Mn-carbonates precipitate directly in anoxic water columns or form diagenetically in sediments has remained unreso...

Metasomatized mantle source and far-field effect of flat-slab subduction at the Huangtuliang gold deposit, northern margin of the North China Craton

The metasomatized lithospheric mantle has been proposed as the primary source for gold mineralization at cratonic margins, yet without much direct evidence. To substantiate this theory with geochemistry, we study ore-hosting alkaline syenite and mineralization-related lamprophyre...

Artificial Intelligence for Mineral Exploration Imagery: A Systematic Mapping Review of Data, Tasks, and Methods

Artificial intelligence (AI) is increasingly applied to image-based and image-formatted geoscientific evidence across mineral exploration, from regional and surface surveys to drilling/core analysis and laboratory characterization. However, the literature remains distributed acro...

Hydrochemical Evolution, Anthropogenic Influences, and Irrigation Suitability of Groundwater in the Zhangye Basin, Northwest China

Groundwater is a critical resource in arid regions, requiring careful evaluation of its quality, source origins, and suitability for irrigation. This study assessed groundwater in three Zhangye Basin irrigation districts using Gibbs diagrams, ionic ratios and correlation analyses...

Contrasting Nitrate Sources and Transport Pathways in a Connected Karst Surface Water and Groundwater System

Nitrate contamination threatens surface water and groundwater quality in karst regions, posing risks to drinking water safety and aquatic ecosystems. Strong surface water–groundwater connectivity in karst recharge areas can accelerate contaminant transport through fractures and c...

High-Throughput Sequencing Reveals Composition, Diversity, and Functional Prediction of Root-Associated Microbial Communities of Dominant Plants in an Ecologically Sensitive Area of the Loess Plateau

The alpine mining area of the Qilian Mountains features a fragile ecosystem, severe soil degradation due to mining disturbances, and slow natural recovery. To clarify the ecological restoration potential of rhizosphere microorganisms associated with native dominant plants, this s...

Genetic links between IIIE iron meteorites and the core of the HED parent asteroid

Rocky planets formed through the differentiation of planetesimals into metal‑rich cores and silicate mantles, yet direct evidence linking these complementary reservoirs remains scarce. Here we show that IIIE irons and howardite-eucrite-diogenite (HED) meteorites are genetically l...
