TL;DR: In this article, microbathymetry data, in situ observations, and sampling along the 13°20′N and 13° 20′N oceanic core complexes (OCCs) reveal mechanisms of detachment fault denudation at the seafloor, links between tectonic extension and mass wasting, and expose the nature of corrugations, ubiquitous at OCCs.

TL;DR: In this paper, the authors analyzed major, trace element and isotopic compositions in three groups of rocks: plagioclase-bearing ultramafic and gabbroic rocks dredged in nearly amagmatic spreading corridors; basalts from the sparse volcanic cover of these corridors, and basalts dredged from the intervening, more volcanically active domains (volcanic seafloor basalts) and inferred that these reactions occur in the walls of conduits that allow the aggregated melts extracted from the melting mantle to rise through the axial lithosphere and to the eruption

TL;DR: In this article, the authors identify a marker of coseismic slip on a submarine fault plane along the Roseau Fault (Lesser Antilles), and measure its vertical displacement of ∼0.9 m in situ.

TL;DR: In this paper, a comprehensive suite of poikilitic shergottites was studied using bulk rock major and trace element compositions, mineral major-element compositions, oxygen fugacity (O2) values, crystallization temperatures, phosphorus maps of olivine grains, and quantitative textural analyses.
