Mesoproterozoic seafloor authigenic glauconite-berthierine: Indicator of enhanced reverse weathering on early Earth

Sedimentary records suggest that the mid-Proterozoic (ca. 1.8–0.8 Ga) was persistently characterized by a greenhouse climate despite significantly lower solar luminosity compared to modern levels

Quantifying the relative contributions of Miocene rivers to the deep Gulf of Mexico using detrital zircon geochronology: Implications for the evolution of Gulf Basin circulation and regional drainage

Sediment routing from hinterland to the deep sea is complicated because it involves evolution of river drainage from source areas to coastal plains and sediment mixing on the shelf and slope by marine currents

Geochemical and O–C–Sr–Nd Isotopic Constraints on the Petrogenetic Link between Aillikites and Carbonatites in the Tarim Large Igneous Province

Aillikites are carbonate-rich ultramafic lamprophyres often associated with carbonatites. Despite their common field relationships, the petrogenetic links, if any, between aillikites and carbonatites remain controversial

Collision-related porphyry Cu deposits formed by input of ultrapotassic melts into the sulfide-rich lower crust

Collision-related porphyry Cu deposits (PCDs) are restricted to previous magmatic arcs, in which sulfide-rich lower crust occurred

The interactions of volcanism and clastic sedimentation in rift basins: Insights from the Palaeogene-Neogene Shaleitian uplift and surrounding sub-bas

Although volcanism is an important process in the evolution of rift basins, current tectono-sedimentary models largely neglect its impact on sediment supply, transport pathways, and depositional systems

Remagnetization Age and Mechanism of Cretaceous Sediments in Relation to Dyke Intrusion, Hainan Island: Tectonic Implications for South China and the

Hainan Island lies near the Red River Fault, a prominent tectonic feature produced by the India-Asia collision

Detrital zircons record the evolution of the Cathaysian Coastal Mountains along the South China margin

The Cathaysian Coastal Mountains are thought to be an ancient high-topographic feature that existed along the margin of South China

Potassium and its isotope behaviour during chemical weathering in a tropical catchment affected by evaporite dissolution

This work presents the systematic investigation of K contents and stable K isotopic compositions of surface waters, groundwater, wastewaters, suspended particles, bed sediments, and fertilizers in the Upper Mun Rive catchment, northeast Thailand

Combined Effects of Fe(III)-Bearing Nontronite and Organic Ligands on Biogenic U(IV) Oxidation

Bioreduction of soluble U(VI) to sparingly soluble U(IV) solids was proposed as a remediation method for uranium contamination

Impacts of active tectonics on geogenic arsenic enrichment in groundwater in the Hetao Plain, Inner Mongolia

High arsenic (As) groundwater has become a serious environmental problem threatening the health of 300 thousand people in the Hetao Plain (HP) of Inner Mongolia, China, where the microscopic mechanisms of As releasing in groundwater have been widely studied
