Characterization of coesite‐bearing impact melt glass from the Hapcheon crater, Korea: Trimodal phase architecture, shock metamorphism, and implications for 40Ar/39Ar geochronology

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...

Rhizosphere Engineering by Root Exudates: High‐Yielding Alfalfa Recruits Functional PGPR to Sustain Soil Nutrient Availability Under Long‐Term Cultivation

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Soil nutrient transformation capacity is a critical determinant of sustainable productivity in perennial cropping systems; however, the extent to which high‐yielding crops actively regulate rhizosphere microbial assembly to maintain nutrient availability remains poorly understood.

Field‐based evaluation of glass cullet as a supplementary sediment source for coastal restoration

open access: yesRestoration Ecology, EarlyView.
There is an ever‐increasing demand for sand to support projects like beach nourishment and dune restoration, but dredging and mining sand causes environmental damage. Demonstrating the environmental and ecological compatibility of crushed and ground glass known as cullet to support coastal restoration projects could simultaneously divert waste from ...

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

open access: yesSedimentology, EarlyView.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources
