The primary purpose of this paper is to investigate the spreading and production rates of oceanic ridges for the last 180 Myr, based on the detailed analysis of eight oceanic units (North, Central, and South Atlantic basins, Southwest, Central, and Southeast Indian Ridge systems, Somalia basin, and the Pacific plate) and using the most recent timescale for oceanic isochrons. The global study of oceanic ridges presented here shows that (1) the average rate of spreading, which we computed by… 
Evidence for a Global Slowdown in Seafloor Spreading Since 15 Ma
The rate of ocean‐crust production exerts control over sea level, mantle heat loss, and climate. Different strategies to account for incomplete seafloor preservation have led to differing conclusions
Mesozoic evolution of NW Africa: implications for the Central Atlantic Ocean dynamics
The Central Atlantic Ocean opened during the Early Jurassic and represents the oldest portion of the Atlantic Ocean. Although the American margin has been well studied, the onshore evolution of its
Does sea level influence mid‐ocean ridge magmatism on Milankovitch timescales?
Magma production at mid‐ocean ridges is driven by seafloor spreading and decompression melting of the upper mantle. In the special case of Iceland, mantle melting may have been amplified by ice sheet
Crustal structure of the French Guiana margin, West Equatorial Atlantic
SUMMARY Geophysical data from the Amazon Cone Experiment are used to determine the structure and evolution of the French Guiana and Northeast Brazil continental margin, and to better understand the


Oceanic crust production and climate during the last 100 Myr
In order to evaluate the possible influence of oceanic crust production on climatic changes during the past 100Myr variations in total oceanic crust for this period including production at mid-ocean
Temporal variation of oceanic spreading and crustal production rates during the last 180 My
Latest pulse of Earth: Evidence for a mid-Cretaceous superplume
A calculation of Earth's ocean crustal budget for the past 150 m.y. reveals a 50% to 75% increase in ocean crust formation rate between 120 and 80 Ma. This "pulse" in ocean crust production is seen
Oceanic Ridge Volumes and Sea-Level Change - An Error Analysis
Sea-level fluctuations due to changing mid-ocean ridge volumes have been calculated for the last 80 m.y. in 5-m.y. intervals. An analysis of the errors involved in this set of calculations includes:
Time scales and dynamic models of deep‐sea sedimentation
Models of very long term geochemical cycling of material include oceanic sediments as a part of the much larger system of mantle differentiation, production of sea floor, subduction, and continental
Global correlations of ocean ridge basalt chemistry with axial depth and crustal thickness
Regional averages of the major element chemistry of ocean ridge basalts, corrected for low-pressure fractionation, correlate with regional averages of axial depth for the global system of ocean
Global correlations of mid-ocean-ridge basalt chemistry with seismic tomographic images
THERMAL convection in the mantle is the most important dynamic process in the Earth's interior. Two quite different approaches are currently used to provide and analyse information regarding lateral
A correlation between mid-ocean-ridge basalt chemistry and distance to continents
The chemistry of mid-ocean-ridge basalt—which reflects the temperature of the source mantle—is examined as a function of the distance of the ridge from the closest continental margin and it is concluded that the location of continental masses relative to active ridges influences the large-scale thermal structure of the mantle.
Petrological systematics of mid-ocean ridge basalts: Constraints on melt generation beneath ocean ridges
Mid-ocean ridge basalts (MORB) are a consequence of pressure-release melting beneath ocean ridges, and contain much information concerning melt formation, melt migration and heterogeneity within the
