Formation of discrete islands in linear island chains
Abstract
Mantle convection studies indicate that large-scale shear beneath plates acts together with the buoyant uplift of the lower density plume material to produce a succession of discrete plumes and consequently island chains such as Hawaii. The spacing of the Hawaiian Islands requires that its low viscosity shear zone is less than 80 km thick.
