Path-Dependent Diagenesis and Facies-Controlled Reservoir Quality in Lower Cretaceous Fan-Delta Sandstones, North Yellow Sea Basin: A Model for Superimposed Rift Basins

The Lower Cretaceous fan-delta sandstones in the North Yellow Sea Basin underwent a distinctive polyphase burial trajectory, offering a natural laboratory to investigate path-dependent diagenesis and its impact on reservoir quality evolution in superimposed rift basins. Integrati...

Flocculation and Dewatering Mechanisms of Pyrite Flotation Tailings: Synergistic Roles of Polyferric Chloride, Polydiallyldimethylammonium Chloride, and Skeleton Builders on Microstructure Evolution

This study investigates the conditioning and deep dewatering of pyrite tailings slurry using a composite system comprising polyferric chloride (PFC), polydiallyldimethylammonium chloride (PDMDAAC), and fly ash as a skeleton builder. The synergistic application significantly enhan...

Integrating Land Use Change and Vegetation Resilience to Assess Ecological Impacts of Expressway Construction: A Case Study of the Linghua Expressway

The rapid expansion of road construction has significantly contributed to economic development and regional connectivity. However, linear infrastructure such as roads, railways, and utility corridors has also introduced considerable ecological disruptions. Although increasing glo...
