The late Mesozoic-Cenozoic tectonic evolution of the South China Sea: A petrologic perspective [PDF]

open access: yes, 2014
This paper presents a review of available petrological, geochonological and geochemical data for late Mesozoic to Recent igneous rocks in the South China Sea (SCS) and adjacent regions and a discussion of their petrogeneses and tectonic implications. The

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 ...

Quantitative Analysis of tectonic activity in Taftan volcano and around (South East of Iran) [PDF]

open access: yesمخاطرات محیط طبیعی, 2016
Taftan volcano young to age Pliocene-Quaternary and semi-active volcanic system is located 50 kilometers north of the city of Khash. It seems in this area the phenomenon of young volcanoes and tectonically active area morphology have played a major role.

Geospatial Analysis for Tectonic Assessment and Soil Erosion Prioritization: A Case Study of Wadi Al-Lith, Red Sea Coast, Saudi Arabia

open access: yesApplied Sciences, 2023
An investigation into tectonics and erosion reveals that they play an important role in causing uplifting, valley incision, and soil erosion. The analysis of drainage basins at different scales is irreplaceable in the development of sustainable plans ...

Tectonics, volcanism, landscape structure and human evolution in the African Rift [PDF]

open access: yes, 2000
Tectonic movements and volcanism in the African Rift have usually been considered of relevance to human evolution only at very large geographical and chronological scales, principally in relation to longterm topographic and climatic variation at the ...

Seismic cycles, size of the largest events, and the avalanche size distribution in a model of seismicity [PDF]

open access: yes, 2012
We address several questions on the behavior of a numerical model recently introduced to study seismic phenomena, that includes relaxation in the plates as a key ingredient.

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Block Motion Changes in Japan Triggered by the 2011 Great Tohoku Earthquake [PDF]

open access: yes, 2017
Plate motions are governed by equilibrium between basal and edge forces. Great earthquakes may induce differential static stress changes across tectonic plates, enabling a new equilibrium state.

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
