Introduction to special section: Hawaii Scientific Drilling Project [PDF]

, 1996
Intraplate or "hot spot" volcanic island chains, exemplified by Hawaii, play an important role in plate tectonic theory as reference points for absolute plate motions, but the origin of these volcanoes is not explained by the plate tectonic paradigm ...

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 ...

From Continent to Ocean: Investigating the Multi-Element and Precious Metal Geochemistry of the Paraná-Etendeka Large Igneous Province Using Machine Learning Tools

Earth Science, Systems and Society, 2021
Large Igneous Provinces, and by extension the mantle plumes that generate them, are frequently associated with platinum-group element (PGE) ore deposits, yet the processes controlling the metal budget in plume-derived magmas remains debated.

Illumina-based transcriptome sequencing of mussel Mytilus coruscus mantle

浙江大学学报. 农业与生命科学版, 2015
Mollusk shell is an exoskeleton made up of organic mineral particles and its function is to protect the inner soft body from predators and environmental damage. Due to its superior mechanical properties, such as stiffness, fracture toughness, and tensile

Transcriptome and digital gene expression analysis reveal immune responses of mantle and visceral mass pearl culturing in Hyriopsis cumingii

Frontiers in Marine Science, 2023
Biomineralization is a widespread phenomenon in marine mollusks and is responsible for the production of shells and pearls. However, the regulatory mechanisms governing the adaptive immune responses in the mollusk mantle and visceral mass during ...

Modeling of residual spheres for subduction zone earthquakes: 1. Apparent slab penetration signatures in the NW Pacific caused by deep diffuse mantle anomalies [PDF]

, 1990
We have computed focal residual spheres for 145 subduction zone earthquakes along the northwest edge of the Pacific using regional and global mantle velocity models from tomographic inversions.

CRUST AND MANTLE OF THE BAIKAL RIFT ZONE FROM P- AND S-WAVE RECEIVER FUNCTIONS

Геодинамика и тектонофизика, 2017
We have obtained P-wave and S-wave receiver functions for 10 broadband seismograph stations in the Baikal rift zone (BRZ) and inverted them for seismic velocity models of the crust and upper mantle.

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).

INTERACTION OF MANTLE-DERIVED MELTS WITH CRUST ON ITS UPWELLING TO THE SURFACE: REASON AND CONSEQUENCE

Геодинамика и тектонофизика, 2015
The work considers the mechanism of upwelling of the basaltic melt to the surface and the reason of its stoppage in the crust. The process of stoppage, probably, is controlled by ratio between density of the basaltic melt and density of the crust.

Mantle heterogeneity during the formation of the North Atlantic Igneous Province: Constraints from trace element and Sr-Nd-Os-O isotope systematics of Baffin Island picrites [PDF]

, 2004
Sr-Nd-Os-O isotope and major and trace element data from ~62 Ma picrites from Baffin Island constrain the composition of mantle sources sampled at the inception of North Atlantic Igneous Province (NAIP) magmatism.
