Abstract
The relief of the South Atlantic is characterized by elevated passive continental margins along southern Africa and eastern Brazil, and by the bathymetric asymmetry of the southern oceanic basin where the western flank is much deeper than the eastern flank. We investigate the origin of these topographic features in the present and over time since the Jurassic with a model of global mantle flow and lithospheric deformation. The model progressively assimilates plate kinematics, plate boundaries and lithospheric age derived from global tectonic reconstructions with deforming plates, and predicts the evolution of mantle temperature, continental crustal thickness, long-wavelength dynamic topography, and isostatic topography. … Read more…

The breakup of east Gondwana: assimilating constraints from Cretaceous ocean basins around India into a best-fit tectonic model, Gibbons et al. (2013)

East GondwanaSummary
Published models for the Cretaceous seafloor-spreading history of East Gondwana result in unlikely tectonic scenarios for at least one of the plate boundaries involved and/or violate particular constraints from at least one of the associated ocean basins. We link East Gondwana spreading corridors by integrating magnetic and gravity anomaly data from the Enderby Basin off East Antarctica within a regional plate kinematic framework to identify a conjugate series of east-west-trending magnetic anomalies, M4 to M0 (~126.7–120.4 Ma). … Read more…

Seawater chemistry driven by supercontinent assembly, breakup and dispersal, Müller et al. (2013)

by

Muller etal Fig1 - Seawater Chemistry Driven by Supercontinental AssemblyCitation
Müller, R. D., Dutkiewicz, A., Seton, M. and Gaina, C. (2013). Seawater chemistry driven by supercontinent assembly, break-up and dispersal Geology. doi 10.1130/G34405.1.

Summary
Global oceans are known to have alternated between aragonite and calcite seas. These oscillations reflect changes in the Mg/Ca ratio of seawater, which control biomineralisation and the composition of marine carbonates and are thought to be caused by the time dependence of crustal accretion at mid-ocean ridge crests and associated high temperature mid-ocean ridge brine flux. Here we use global ocean basin reconstructions to demonstrate that these fluctuations are instead caused by the gradual growth and destruction of mid-ocean ridges and their relatively cool flanks during long-term tectonic cycles thus linking ocean chemistry to off-ridge low temperature hydrothermal flux. Early Jurassic aragonite seas were a consequence of supercontinent stability and minima in mid-ocean ridge length and basalt alteration. The break-up of Pangaea led to a gradual doubling in ridge length and a 50% increase in hydrothermal flux mainly through an enormous increase in ridge flank area, leading to enhanced alteration of basalt, lowered seawater Mg/Ca ratios and marine hypercalcification from 140 to 35 Ma. … Read more…

A review of observations and models of dynamic topography

Flament-et-al_fig1Summary
The topography of Earth is primarily controlled by lateral differences in the density structure of the crust and lithosphere. In addition to this isostatic topography, flow in the mantle induces deformation of its surface leading to dynamic topography. This transient deformation evolves over tens of millions of years, occurs at long wavelength, and is relatively small (<2 km) in amplitude. Here, we review the observational constraints and modeling approaches used to understand the amplitude, spatial pattern, and time dependence of dynamic topography. … Read more…

Understanding the deep driving forces of Earth’s large-scale topography through time

by

Global paleogeography figureProject Summary
Continents and sedimentary basins through time record fundamental Earth system cycles, reflecting environmental change, migration of fauna and flora and shifting coastlines. It was originally thought that successive advances and retreats of shallow inland seas mainly reflect global sea level variations (eustasy). It is now well known in principle that large-scale surface morphology such as the high topography of the East African Rift, the low-lying Amazon River Basin and the southwest to northeast tilt of the Australian continent are strongly controlled by processes deep within the Earth, but progress has been slow in quantifying the magnitude and time-dependence of these relationships. … Read more…
