TLDR
A recent survey of the Mid-Atlantic Ridge over the southern edge of the Azores Platform shows that two anomalously shallow regions located off-axis on both sides of the ridge are the two flanks of a single rifted volcanic plateau as mentioned in this paper.About:

Geologically current plate motions
TL;DR: MORVEL as discussed by the authors is a new closure-enforced set of angular velocities for the geologically current motions of 25 tectonic plates that collectively occupy 97 per cent of Earth's surface.
Journal ArticleDOI
The mean composition of ocean ridge basalts
TL;DR: In this article, the mean composition of mid-ocean ridge basalts (MORB) is determined using a global data set of major elements, trace elements, and isotopes compiled from new and previously published data.
Journal ArticleDOI
Evolution and Biogeography of Deep-Sea Vent and Seep Invertebrates
TL;DR: The recent evolution of many vent and seep invertebrate species suggests that Cenozoic tectonic history and oceanic circulation patterns have been important in defining contemporary biogeographic patterns.

Discovery of a magma chamber and faults beneath a Mid-Atlantic Ridge hydrothermal field
Satish C. Singh,Wayne C Crawford,H. Carton,Tim Seher,Violaine Combier,Mathilde Cannat,Juan Pablo Canales,D. Dusunur,Javier Escartín,J. Miguel Miranda +9 more
TL;DR: It is suggested that this magma chamber beneath the slow-spreading Lucky Strike segment of the Mid-Atlantic Ridge provides the heat for the active hydrothermal vent field above it, and axial valley bounding faults that seem to penetrate down to the magMA chamber depth are observed, suggesting continuous interactions between tectonic and magmatic processes.

TiO 2 enrichment in ocean island basalts
Julie Prytulak,Tim Elliott +1 more
TL;DR: In this paper, an extensive dataset of ocean island basalt (OIB) compositions highlight that their titanium contents are generally too high to be derived from melting of a peridotitic mantle.

Free software helps map and display data
Paul Wessel,Walter H. F. Smith +1 more
TL;DR: The Generic Mapping Tools (GMT) is introduced, which is a free, public domain software package that can be used to manipulate columns of tabular data, time series, and gridded data sets and to display these data in a variety of forms ranging from simple x-y plots to maps and color, perspective, and shaded-relief illustrations.

Revised calibration of the geomagnetic polarity timescale for the Late Cretaceous and Cenozoic
Steven C. Cande,Dennis V. Kent +1 more
TL;DR: An adjusted geomagnetic reversal chronology for the Late Cretaceous and Cenozoic is presented that is consistent with astrochronology in the Pleistocene and Pliocene and with a new timescale for the Mesozoic.
Journal ArticleDOI
Current plate motions
TL;DR: A global plate motion model, named NUVEL-1, which describes current plate motions between 12 rigid plates is described, with special attention given to the method, data, and assumptions used as discussed by the authors.
Current plate motions
TL;DR: In this paper, a new global model (NUVEL-1) was proposed to describe the geologically current motion between 12 assumed-rigid plates by inverting plate motion data.

An analysis of the variation of ocean floor bathymetry and heat flow with age
Barry Parsons,John G. Sclater +1 more
TL;DR: In this paper, a simple cooling model and the plate model were proposed to account for the variation in depth and heat flow with increasing age of the ocean floor. But the results were limited to the North Pacific and North Atlantic basins.
