Abstract
Summary
The Arabian Platform is unusually wide, thick and oil-rich. We explain this as due to the effects of melt produced in the asthenosphere during rifting, meaning 1) the plate remained elevated as a result of buoyancy and 2) the plate was thickened by intrusions allowing it extend more than is usually assumed. Later, at break-up, melt was released at the new Tethyan oceanic spreading centre causing the rifted margins to subside rapidly, with the accommodation space filled by prolific carbonates and evaporites.
