Continental break-up mechanism; lessons from intermediate- and fast-extension settings
<p>Continental break-up mechanisms vary systematically between slow- and fast-extension systems. Slow-extension break-up has
been established from studies of the Central Atlantic, European and Adria margins. This study focuses on the intermediate
and fast cases from Gabon and East India, and draws from the interpretation of reflection seismic, gravimetric and magnetic
data.
</p> <p>Interpretation indicates continental break-up via continental mantle unroofing in all systems, with modifications produced
by magmatism in faster-extension systems. Break-up of the intermediate-extension Gabon system involves partial upper continental
crustal decoupling from continental mantle; whereas, in the fast East Coast India system, decoupled and lower-crustal regimes
underwent upwarping in âsoggyâ zones in the footwalls of major normal faults. Usually, upper-crustal break-up is affected
by pre-existing anisotropies, which form systems of constraining ârailsâ for extending continental crust. This modifies the
local stress regimes. They regain a regional character as the function of constraining rails vanishes during progressive unroofing
of the upper mantle. Different regions attain different amounts of upper-crustal stretching prior to the break-up. The break-up
location is then controlled by the upper-crustal energy balance principle of âwound linkageâ, by which the minimum physical
work is performed for linking upper-crustal âwoundsâ, leading to successful upper-crustal break-up.
