Response to Comment on “Mantle Flow Drives the Subsidence of Oceanic Plates”

چکیده
Croon et al. challenge our conclusion that sea-floor depth variations are driven by the underlying mantle convection. We point out that, contrary to their claim, our data analysis is pertinent and that the sea-floor linear trend as the square root of the distance from the ridge is a robust observation. The mechanism responsible for this trend is an asthenospheric flow, faster than the overlying plate, which shapes the lithosphere structure.

Comment on "Mantle flow drives the subsidence of oceanic plates".
Adam and Vidal (Reports, 2 April 2010, p. 83) reported sea-floor depth increasing as the square root of distance from the ridge along "mantle flow lines." However, their data actually support a depth-age relationship and "flattening" at older ages. We argue that no plausible physical mechanism supports their proposal that mantle flow drives subsidence.
متن کاملMantle flow drives the subsidence of oceanic plates.
The subsidence of the sea floor is generally considered a consequence of its passive cooling and densifying since its formation at the ridge and is therefore regarded as a function of lithospheric age only. However, the lithosphere is defined as the thermal boundary layer of mantle convection, which should thus determine its structure. We examined the evolution of the lithosphere structure and ...
متن کاملEvolution of young oceanic lithosphere and the meaning of seafloor subsidence rate
Plate tectonics, a special class of mantle convection so far observed only on the Earth, is responsible for a vast array of geological processes, from the generation of continental crust to the modulation of atmospheric composition. Whereas conditions for its operation are still debated, the minimum requirement is generally thought that surface plates become denser than the underlying asthenosp...
متن کاملKinematics and dynamics of the East Pacific Rise linked to a stable, deep-mantle upwelling
Earth's tectonic plates are generally considered to be driven largely by negative buoyancy associated with subduction of oceanic lithosphere. In this context, mid-ocean ridges (MORs) are passive plate boundaries whose divergence accommodates flow driven by subduction of oceanic slabs at trenches. We show that over the past 80 million years (My), the East Pacific Rise (EPR), Earth's dominant MOR...
متن کاملSubsidence of normal oceanic lithosphere, apparent thermal expansivity, and seafloor flattening
Seafloor topography has been a key observational constraint on the thermal evolution of oceanic lithosphere, which is the top boundary layer of convection in Earth's mantle. At least for the first ~70 Myr, the age progression of seafloor depth is known to follow the prediction of half-space cooling, and the subsidence rate is commonly believed to be ~350 m Ma. Here we show that, based on a new ...
