Mantle plumes [PDF]

Proceedings of the National Academy of Sciences, 2013
Volcanoes are usually found near the borders of tectonic plates that are violently either pushing or pulling at each other. Mysteriously, however, volcanoes sometimes erupt in the middle of these plates instead. The culprits behind these outbursts might be giant pillars of hot molten rock known as mantle plumes, jets of magma rising up from near the ...

Rat Kidney Cancers Determined by Dietary Ochratoxin A in the First Year of Life

Journal of Kidney Cancer and VHL, 2016
An experiment to explore renal carcinogenic efficacy of male rat exposure to dietary ochratoxin A (OTA) only in the first year of life has been made in comparison to lifetime exposure. Ten months exposure to OTA at 300 μg/kg b.w.

Mid-mantle deformation inferred from seismic anisotropy [PDF]

, 2002
With time, convective processes in the Earth's mantle will tend to align crystals, grains and inclusions. This mantle fabric is detectable seismologically, as it produces an anisotropy in material properties—in particular, a directional dependence in ...

Active Degassing of Deeply Sourced Fluids in Central Europe: New Evidences From a Geochemical Study in Serbia

Geochemistry, Geophysics, Geosystems, 2021
We report on the results of an extensive geochemical survey of fluids released in the Vardar zone (central‐western Serbia), a mega‐suture zone at the boundary between Eurasia and Africa plates.

Geophysical and geochemical constraints on geoneutrino fluxes from Earth's mantle [PDF]

, 2012
Knowledge of the amount and distribution of radiogenic heating in the mantle is crucial for understanding the dynamics of the Earth, including its thermal evolution, the style and planform of mantle convection, and the energetics of the core.

Geochemical insights into the role of metasomatic hornblendite in generating alkali basalts

Geochemistry, Geophysics, Geosystems, 2014
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.

Matter Enhanced Neutrino Oscillations with a Realistic Earth Density Profile [PDF]

, 2000
We have investigated matter enhanced neutrino oscillations with a mantle-core-mantle step function and a realistic Earth matter density profile in both a two and a three neutrino scenario.

Some features of the structure of the mantle of the Eastern Mediterranean and their geodynamic interpretation

Геофизический журнал, 2016
We consider specific velocity anomalies and the corresponding mantle structures of the East Mediterranean-Black Sea-Caspian region. The anomalies are located on latitudinal and longitudinal seismic tomography sections obtained by constructing 3D P ...

Sr-Nd-Pb-Hf isotope results from ODP Leg 187: Evidence for mantle dynamics of the Australian-Antarctic Discordance and origin of the Indian MORB source [PDF]

, 2002
New high precision PIMMS Hf and Pb isotope data for 14–28 Ma basalts recovered during ODP Leg 187 are compared with zero-age dredge samples from the Australian-Antarctic Discordance (AAD).

Melting and Mixing States of the Earth's Mantle after the Moon-Forming Impact [PDF]

, 2015
The Earth's Moon is thought to have formed by an impact between the Earth and an impactor around 4.5 billion years ago. This impact could have been so energetic that it could have mixed and homogenized the Earth's mantle. However, this view appears to be
