Macrostrat: A Platform for Geological Data Integration and Deep‐Time Earth Crust Research [PDF]

open access: bronze, 2018
Characterizing the lithology, age, and physical‐chemical properties of rocks and sediments in the Earth's upper crust is necessary to fully assess energy, water, and mineral resources and to address many fundamental questions.

Dendritic crystallization in hydrous basaltic magmas controls magma mobility within the Earth’s crust

open access: yesNature Communications, 2022
The majority of basaltic magmas stall in the Earth’s crust as a result of the rheological evolution caused by crystallization during transport. However, the relationships between crystallinity, rheology and eruptibility remain uncertain because it is ...

Evidence for the oxidation of Earth’s crust from the evolution of manganese minerals

open access: yesNature Communications, 2022
Analysis of manganese mineral occurrences and valence states demonstrate oxidation of Earth’s crust through time. Changes in crustal redox state are critical to Earth’s evolution, but few methods exist for evaluating spatially averaged crustal redox ...

Efficient Removal of Congo Red, Methylene Blue and Pb(II) by Hydrochar–MgAlLDH Nanocomposite: Synthesis, Performance and Mechanism

open access: yesNanomaterials, 2023
Organic dyes and heavy metals often coexist in industrial effluents, and their simultaneous removal is a grand challenge. Herein, a hydrochar and MgAl layered double hydroxide (HC–MgAlLDH) nanocomposite was prepared via a facile one-step hydrothermal ...

There were no large volumes of felsic continental crust in the early Earth [PDF]

open access: yes, 2017
New model growth curves for the continental crust based upon Hf-isotopes in zircon suggest that large volumes of felsic continental crust were present in the Hadean and early Archaean.

Pinch and swell structures: evidence for strain localisation by brittle–viscous behaviour in the middle crust [PDF]

open access: yesSolid Earth, 2015
The flow properties of middle crustal rocks are commonly represented by viscous flow. Examples of pinch and swell structures found in a high strain zone at St.

The influence of gold mining wastes on the migration-transformation behavior and health risks of arsenic in the surrounding soil of mined-area

open access: yesFrontiers in Earth Science, 2023
Understanding the characteristic heavy metals and their migration-transformation behavior in mining areas is essential for the prevention and control of mining pollution.

Collisional stripping of planetary crusts [PDF]

open access: yes, 2017
Geochemical studies of planetary accretion and evolution have invoked various degrees of collisional erosion to explain differences in bulk composition between planets and chondrites.

Special features of distribution of seismic waves propagation velocity in the Earth crust in the area of uranium deposits (Kirovograd ore area of Ingul megablock of the Ukrainian Shield)

open access: yesГеофизический журнал, 2015
Principal possibility of detailed study of velocity characteristics of crystalline Earth crust in the areas of uranium deposits has been shown. By comparison with geologic data an assumption has been expressed on increased concentration of sodium ...
