The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins
Terra Nova, EarlyView.ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;

Research of ore elements migration forms in the hydrothermal solutions of the Mid-Atlantic ridge
Известия высших учебных заведений: Геология и разведка, 2016 On the basis of geological and hydrogeochemical analysis, the issue of forming of hydrothermal plumes in Atlantic Ocean is considered. Forms of the ore elements migration in hydrothermal solutions of the Logachev vent field (14°45' N) were researched ...

The role of synoptic waves in the formation and maintenance of the Western Hemisphere circulation pattern [PDF]
, 2017 Previous studies have demonstrated that the NAO, the leading mode of atmospheric low-frequency variability over the North Atlantic, could be linked to Northeast Pacific climate variability via the downstream propagation of synoptic waves.

Ultra-depleted melts from Kamchatkan ophiolites : evidence for the interaction of the Hawaiian plume with an oceanic spreading center in the Cretaceous? [PDF]
, 2009 We report new data on the major and trace element composition of melt inclusions in spinel phenocrysts (Mg# = 0.7-0.8, Cr/(Cr + Al) = 0.32-0.52, TiO2 = 0.06-0.60 wt.%) from Cretaceous MORB-like basalt (La/Yb = 0.94, Th/Nb = 0.055, Th/La = 0.041) in the ...

Interaction of the North Atlantic Current with the deep Charlie Gibbs Fracture Zone throughflow [PDF]
, 1999 The Charlie Gibbs Fracture Zone (CGFZ), a passage of 3600 m sill depth through the Mid‐Atlantic Ridge near 52°N, is a known gateway for the passage of deep waters from the Northeast Atlantic into the western basin.

The Agulhas Ridge, South Atlantic: the peculiar structure of a fracture zone [PDF]
, 2005 The Agulhas Ridge is a prominent topographic feature that parallels the Agulhas-Falkland Fracture Zone (AFFZ). Seismic reflection and wide angle/refraction data have led to the classification of this feature as a transverse ridge.
