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.

FALL OF RELATIVE SEA LEVELS DURING THE LGM AND THE ROLE OF THE LOWER MANTLE LAYERS IN MANIFESTATION OF THE EFFECT OF HYDROISOSTASY

Геодинамика и тектонофизика, 2023
The structure and functioning of coastal geosystems depend on the interaction of exogenous and endogenous factors. The results of such interaction can dramatically affect both the ecological situation and economic activity.

Geoelectric heterogeneities of the Kerch iron ore basin

Геофизический журнал, 2021
The three-dimensional geoelectric model of the Earth’s crust and upper mantle of the Kerch Peninsula has been built for the first time based on the results of experimental observations of the Earth’s low-frequency electromagnetic field, carried out in ...

Characterisation and identification of ectomycorrhizae formed by the species of Asproinocybe (Tricholomataceae) and Inocybe (Inocybaceae) with the roots of the tropical sal tree Shorea robusta (Dipterocarpaceae)

Ukrainian Botanical Journal, 2021
In the course of the present study, surveys on occurrence and distribution of ectomycorrhizal (EcM) fungi in tropical sal forests of foothills of the Himalayas, India, were undertaken. The species of two genera of agarics, namely Asproinocybe and Inocybe,

Three‐dimensional flow in the subslab mantle

Geochemistry, Geophysics, Geosystems, 2014
Three‐dimensional models of mantle flow at subduction zones make it possible to explain the common occurrence of trench‐parallel subslab seismic anisotropy.

The Anelasticity of the Mantle* [PDF]

Geophysical Journal of the Royal Astronomical Society, 2010
The attenuation of seismic waves provides the most direct data regarding the non-elastic properties of the Earth. Recent experimental results from body waves, surface waves and free oscillations provide estimates of the anelasticity in various regions of the Earth.

Folian-cv1 Is a Member of a Highly Acidic Phosphoprotein Class Derived From the Foliated Layer of the Eastern Oyster (Crassostrea virginica) Shell and Identified in Hemocytes and Mantle

Frontiers in Marine Science, 2019
The proteins derived from the foliated shell layer of the oyster, Crassostrea virginica, are unusually acidic and highly phosphorylated. Here we report the identification of a gene encoding a member of this class of phosphoproteins that we collectively ...

Mantle plumes and mantle dynamics in the Wilson cycle [PDF]

Geological Society, London, Special Publications, 2018
Abstract This review discusses the thermal evolution of the mantle following large-scale tectonic activities such as continental collision and continental rifting. About 300 myr ago, continental material amalgamated through the large-scale subduction of oceanic seafloor, marking the termination of one or more oceanic basins (e.g.

A Rhodopsin-Like Gene May Be Associated With the Light-Sensitivity of Adult Pacific Oyster Crassostrea gigas

Frontiers in Physiology, 2018
Light-sensitivity is important for mollusc survival, as it plays a vital role in reproduction and predator avoidance. Light-sensitivity has been demonstrated in the adult Pacific oyster Crassostrea gigas, but the genes associated with light-sensitivity ...
