Early Cretaceous–Late Miocene Basin–Mountains Pattern in the Northeastern Margin of the Tibetan Plateau, NW China: Evidence From Detrital Zircon Chronology in the Lanzhou Basin

Geological Journal, EarlyView.
Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.

Geodynamic modeling on subduction-spreading interaction and implications for the South China Sea and surrounding regions

Geosystems and Geoenvironment, 2023
The convergent subduction zones and the divergent spreading ridges are essential tectonic units that are widely distributed in the South China Sea and the surrounding regions, governing the regional tectonic evolution.

Experimental dissolution of carbonaceous materials in water at 1 GPa and 550°C: Assessing the role of carbon forms and redox state on COH fluid production and composition during forearc subduction of organic matter

Frontiers in Earth Science, 2023
Biogenic carbonaceous material (CM) is the main carrier of organic carbon in the subduction zone and contributes to COH fluid production and volcanic arc gaseous emissions.

Integration of natural data within a numerical model of ablative subduction: A possible interpretation for the Alpine dynamics of the Austroalpine crust [PDF]

Journal of Metamorphic Geology, 2012, 2012
A numerical modelling approach is used to validate the physical and ge- ological reliability of the ablative subduction mechanism during Alpine con- vergence in order to interpret the tectonic and metamorphic evolution of an inner portion of the Alpine belt: the Austroalpine Domain.

Nutrient limitation dampens the response of a harmful algae to a marine heatwave in an upwelling system

Limnology and Oceanography, EarlyView.
Abstract Harmful algal blooms caused by toxin‐producing species of the diatom genus Pseudo‐nitzschia have been linked to anomalously warm ocean conditions in the Northern California Current System. This study compares summertime concentrations of Pseudo‐nitzschia spp.

Tectonic control on great earthquake periodicity in south-central Chile

Communications Earth & Environment
Multi-millennial records of great megathrust earthquakes have highlighted differences in periodicity and recurrence behavior. Understanding tectonic processes responsible for these differences is relevant for fault mechanics and hazard models.

Continental Growth and Recycling in Convergent Orogens with Large Turbidite Fans on Oceanic Crust

Geosciences, 2013
Convergent plate margins where large turbidite fans with slivers of oceanic basement are accreted to continents represent important sites of continental crustal growth and recycling.

Subduction Evolution Controlled Himalayan Orogenesis: Implications from 3-D Subduction Modeling

Applied Sciences, 2022
Himalayan orogenesis remains enigmatic in terms of Tibetan Plateau geodynamics originating from the Cenozoic India–Eurasian continental collision. India underthrusts below Tibet to the Yarlung–Tsangpo suture, which has been identified as the northernmost

Bloom compression alongside marine heatwaves contemporary with the Oregon upwelling season

Limnology and Oceanography, EarlyView.
Abstract Marine heatwave (MHW) events have led to acute decreases in primary production and phytoplankton biomass in the surface ocean, particularly at the mid latitudes. In the Northeast Pacific, these anomalous events have occasionally encroached onto the Oregon shelf during the ecologically important summer upwelling season.
