Geodynamic features of joint zone of the Eurasian plate and the Alpine-Himalayan belt within the limits of Ukraine and adjacent areas

Геофизический журнал, 2014
Based on the analysis of geophysical and geological data of recent 10—15 years the boundaries and inner structure of the transition zone from the Eurasian plate (EAP) to the Alpine- Himalayan folded belt (AHB) extending from the Eastern Carpathians to ...

Shear-induced material transfer across the core-mantle boundary aided by the post-perovskite phase transition

, 2005
We present a novel mechanical model for the extraction of outer core material upwards across the CMB into the mantle side region of D" and subsequent interaction with the post-perovskite (ppv) phase transition.

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Ultra‐Mafic Cumulates From Kaupulehu, Hualālai Volcano, Hawai'i: Geochemical Resetting of Mantle‐Inherited Olivine

Geochemistry, Geophysics, Geosystems
We characterized the chemical composition and microstructure of six ultramafic cumulates from the Kaupulehu lava flow, Hualālai (Hawai'i Island), to decipher their origin. The samples are mostly wehrlites with poikilitic textures.

A Comparative Study of the Fatty Acid Profile of Non-Edible and Edible Tissues of Raw and Processed Common Octopus (Octopus vulgaris)

Marine Drugs
A comparative study of the fatty acid (FA) composition of non-edible (viscera) and edible (mantle and arm) tissues of octopus (Octopus vulgaris) was carried out.

Velocity model of the mantle structure under Sumatra and seismic activity of the area

Геофизический журнал, 2014
Within the framework of a three-dimensional P-velocity model of the mantle of the South-East Asia, the mantle velocity structure beneath Sumatra and its surroundings has been considered with the identification of possible premises in the deep structure ...

Time constraints on the formation of lithospheric mantle beneath cratons: a re-Os isotope and platinum group element study of peridotite xenoliths from northern Canada and Lesotho, [PDF]

, 2001
Understanding the generation and evolution of cratonic lithospheric keels requires detailed knowledge of their age, timescale of formation, and the relationship between the crust and mantle part of the lithosphere.

Late Pleistocene Volcanic Rocks From Tengchong Volcanic Field at SE Tibetan Plateau: Constraints on Petrogenesis and Mantle and Crustal Processes

Geological Journal, EarlyView.
Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...

Comparative Nutritional and Healthy Values of Macro- and Microelements in Edible and Non-Edible Tissues of Raw and Processed Common Octopus (Octopus vulgaris)

Foods
The macroelement (Na, Mg, P, S, K, and Ca) and microelement (Mn, Fe, Co, Cu, Zn, As, Cd, Sn, Ba, and Pb) composition of edible (arm and mantle) and non-edible (viscera) tissues of octopus (Octopus vulgaris) was studied.

Performance of commercial polyamide membranes in pervaporation for dye removal: Impact of dye classes, colors, and surfactants

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Water reclamation in the textile industry is essential to reduce environmental impacts associated with high water consumption and pollutant discharge. Among emerging technologies, pervaporation (PV) has gained attention due to its high selectivity and efficiency in contaminant removal. However, there is still a lack of comprehensive
