Antineutrino Geophysics with Liquid Scintillator Detectors [PDF]

open access: yes, 1997
Detecting the antineutrinos emitted by the decay of radioactive elements in the mantle and crust could provide a direct measurement of the total abundance of uranium and thorium in the Earth.

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.

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 ...

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 ...

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.

Earth crust vertical movements according to ITRF2000, ITRF2005, ITRF2008 and ITRF2014 coordinate systems and their comparing analysis

open access: yesGeodesy and Geodynamics, 2018
The analysis of Earth’s crust movement vertical velocities was made both for separate regions, and averaged on regions. As input data coordinates and velocities of earth crust points, obtained in International Coordinate Systems ITRF2000, ITRF2005 ...
