THE ORIGIN AND STRUCTURE OF THE LOWER CRUST OF OCEANS AND BACK-ARC SEAS: EVIDENCE FROM THE MARKOV DEEP (MID-ATLANTIC RIDGE) AND THE VOIKAR OPHIOLITE ASSOCIATION (POLAR URALS)

open access: yesГеодинамика и тектонофизика, 2019
The Markov Deep (the axial part of the slow-spreading Mid-Atlantic Ridge, 6°N, Sierra Leone oceanic core complex) and the Paleozoic Voikar ophiolite association (Polar Urals) formed in the back-arc sea conditions.

Ultra-high temperature metamorphism in the Guaxupé Complex: a lower crust segment

open access: yesBrazilian Journal of Geology, 2020
The area is located at the northern boundary of the Guaxupé Complex, which corresponds to the northern domain of the Socorro-Guaxupé Nappe, in the Southern Brasília Orogen, close to the Varginha Shear Zone.

Modelling S-Wave Velocity Structure Beneath the Central Main Ethiopian Rift Using Receiver Functions

open access: yesFrontiers in Earth Science, 2022
We applied the receiver function (RF) technique on high-quality teleseismic earthquake data recorded by the RiftVolc broadband network from February 2016 to October 2017.

Quality Properties of Dry-Aged Beef (Hanwoo Cattle) Crust on Pork Patties

open access: yesFoods, 2022
This study evaluated the effects of crust derived from dry-aged beef (Hanwoo cattle) on the quality of pork patties. Pork patty samples were prepared with different amounts of crust (0—control, 1, 2, and 3%).

A Role for Subducted Oceanic Crust in Generating the Depleted Mid‐Ocean Ridge Basalt Mantle

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The composition of Earth's mantle, continental crust, and oceanic crust continuously evolve in response to the dynamic forces of plate tectonics and mantle convection.

The continental record and the generation of continental crust [PDF]

open access: yes, 2012
Continental crust is the archive of Earth history. The spatial and temporal distribution of Earth's record of rock units and events is heterogeneous; for example, ages of igneous crystallization, metamorphism, continental margins, mineralization, and ...

Drilling the oceanic lower crust and mantle : a global strategy for exploring the deep oceanic crust and mantle in the 1990's [PDF]

open access: yes, 1989
Workshop on Drilling the Oceanic Lower Crust and Mantle, March 7-10, 1989This workshop was convened to follow up on the Second Conference on Scientific Ocean Drilling (COSOD II) to devise a specific plan for deep crustal and mantle drilling over the ...

Early Postseismic Deformation of the 2010 Mw 6.9 Yushu Earthquake and Its Implication for Lithospheric Rheological Properties

open access: yesGeophysical Research Letters, 2022
We used the 250‐day postseismic displacements derived from Global Positioning System data to explore various postseismic deformation processes of the 14 April 2010 Mw 6.9 Yushu earthquake, including the afterslip of the fault, viscoelastic relaxation in ...

Crustal structure of the Ethiopian Northwestern Plateau and central Afar from receiver function analysis

open access: yesFrontiers in Earth Science, 2023
In magma-rich continental rifts extension by magma intrusion is thought to accommodate much of the extension. We aim to constrain major melt reservoirs in the crust during magma-rich rifting by applying P-to-S receiver functions (RFs) using legacy ...
