Lithium isotope geochemical studies of oceanic-type eclogites benefited from previous investigation of altered oceanic crust; however, processes of lithium isotope exchange operating on altered protoliths of continental-type eclogites have remained ...

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 ...

No evidence for high-pressure melting of Earth’s crust in the Archean
Much of the present-day volume of Earth’s continental crust had formed by the end of the Archean Eon, 2.5 billion years ago, through the conversion of basaltic (mafic) crust into sodic granite of tonalite, trondhjemite and granodiorite (TTG) composition.

Expected geoneutrino signal at JUNO [PDF]
Constraints on the Earth's composition and on its radiogenic energy budget come from the detection of geoneutrinos. The KamLAND and Borexino experiments recently reported the geoneutrino flux, which reflects the amount and distribution of U and Th inside

Relations between vertical and horizontal movements of the Earth crust
Horizontal and vertical movements of the Earth crust are interrelated, because the same forces affecting the Earth crust cause them. There is a both-side interrelation between deformations of the Earth crust and spreading of tectonic tensions.

Thickness and structure of the martian crust from InSight seismic data
Single seismometer structure Because of the lack of direct seismic observations, the interior structure of Mars has been a mystery. Khan et al., Knapmeyer-Endrun et al., and Stähler et al.

Determination of Silicon Isotopic Compositions of Rock and Soil Reference Materials by MC-ICP-MS
BACKGROUND With the analytical technique development, the precision of Si isotopes analysis increases rapidly.Silicon isotopes are widely used in geochemistry, cosmochemistry, environmental chemistry and so on, and can be used to trace the circulation of

Geochemical insights into the role of metasomatic hornblendite in generating alkali basalts
Experimental petrology suggested the role of hornblendite in generating alkali basalt. This mechanism is confirmed by an integrated study of major‐trace elements and radiogenic isotopes for Mesozoic alkali basalts from the Qinling orogen in China.
