BSGF - Earth Sciences Bulletin, 2021 The architecture and tectono-magmatic evolution of the lithosphere of Europe are the result of a succession of subduction, rifting and inputs from plumes that have modified the lithospheric mantle since the Neoproterozoic (750–500 Ma).

Geochemistry, Geophysics, Geosystems, 2023 The Cretaceous High Arctic Large Igneous Province (HALIP) in Canada involved extrusion of continental flood basalts (CFBs) at 130–120 Ma and 100‐95 Ma and emplacement of an extensive sill and dike network that intersected the Carboniferous to Paleogene ...

The effect of the mantle and core matter phase state on the course of geodynamic processes
Геофизический журнал, 2023 The study of the course of geodynamic processes in the lower crust and upper mantle proves that an additional energy contribution is made by a change in the phase state of matter with increasing pressure and temperature.

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.

Rare earth element characteristics of pyrope garnets from the Kaavi-Kuopio kimberlites - implications for mantle metasomatism [PDF]
Bulletin of the Geological Society of Finland, 2005 Peridotitic garnet xenocrysts from five kimberlite pipes in the Kaavi-Kuopio area of eastern Finland have been studied using major and trace element geochemistry to obtain information on the stratigraphy, compositional variability and evolutionary ...

Eos, Transactions American Geophysical Union, 1971 There have been two main avenues of investigation of the rheology of the mantle: theoretical and laboratory studies of the mechanical behavior of solids and direct estimates obtained by comparing geologic observations with model calculations in which rheological parameters are the principal variables.

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 ...

Seismic tomography of the mantle and primary hydrogen deposits in the Dnieper-Donetsk basin
Геофизический журнал, 2022 According to the three-dimensional P-velocity model of the mantle under Eurasia obtained by the Taylor approximation method, the analysis of the velocity structure of the mantle (to depths of 2500 km south of 50° N and 1700 km north) in the territory of

Nature, 2001 Seismological images of the Earth's mantle reveal three distinct changes in velocity structure, at depths of 410, 660 and 2,700 km. The first two are best explained by mineral phase transformations, whereas the third-the D" layer-probably reflects a change in chemical composition and thermal structure.
