The evolution of plate tectonics

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
To understand how plate tectonics became Earth's dominant mode of convection, we need to address three related problems. (i) What was Earth's tectonic regime before the present episode of plate tectonics began?

Interplay of tectonics and erosion controls the exhumation of the Tso-Morari Crystallines in the India–Asia collision zone

open access: yesAll Earth
Understanding the exhumation history of the gneissic domes in continental collision zones is vital for deciphering the orogen’s geodynamic evolution. This study uses the zircon and apatite fission track (ZFT and AFT) dataset and thermokinematic modeling ...

Plate Tectonics

open access: yes, 2019
Plate tectonics is the root concept underpinning our current knowledge of how Earth's internal dynamics are linked to geologic deformation at the surface. Since the discovery of plate tectonics in the 1960s, geoscientists have developed a first-order understanding of a plate system in which the Earth's surface is broken into about a dozen mostly rigid ...

Solar Heating Enhanced Selective Recovery of Metal Ions Through Flowing Electrodes Enabled by Hybrid Carbon Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A new electrochemical system based on a microporous hybrid of carbon nanoplatelets and nanotubes to selectively capture Ni2+ from wastewater is constructed. The system temperature rises rapidly when irradiated with sunlight, which enhances the Ni2+ removal rate by 250% and the selectivity by 53%, and the energy consumption is also reduced by 51 ...

Landslide damage along Araniko highway and Pasang Lhamu highway and regional assessment of landslide hazard related to the Gorkha, Nepal earthquake of 25 April 2015

open access: yesGeoenvironmental Disasters, 2017
Background The Gorkha, Nepal Mw 7.8 earthquake of 25 April 2015 triggered a large number of coseismic landslides in a broad area. Two highways, Araniko Highway and Pasang Lhamu Highway, that connect Tibet of China and Nepal, were affected seriously by ...

Integration of Vertical and Horizontal Deformation Derived by SAR Observation for Identifying Landslide Motion Patterns in a Basaltic Weathered Crust Region of Guizhou, China

open access: yesRemote Sensing, 2022
In recent years, due to adverse geological conditions, intense human engineering activities, and extreme weather conditions, catastrophic landslides have frequently occurred in southwest China, causing severe loss of life and property.

Tailored Design of Iridium Single Atoms on Mn–Ni‐Phytate with Robust Bifunctionality for Enhanced Anion Exchange Membrane Water Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
This work presents a manganese‐doped nickel hydroxide scaffold that anchors iridium as isolated single atoms (SAs) using a phytate ligand. The hierarchical nanoarray catalyst efficiently drives simultaneous hydrogen and oxygen evolution in alkaline media, enabling industrial‐level current densities and long‐term stability in an anion‐exchange‐membrane ...

Cl-Bearing Mineral Microinclusions in Arc Lavas: An Overview of Recent Findings with Some Metallogenic Implications

open access: yesGeosciences
Quaternary lavas (ankaramite, basalt, basaltic andesite, andesite, dacite) from the Kamchatka, Kurile, Ecuador and Cascade volcanic arcs contain Cl-bearing mineral microinclusions in rock-forming minerals and groundmass volcanic glass.

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known
