A thermal and mechanical model is constructed for the genesis of oceanic crust. Magma ceases to rise within the oceanic crust when a freezing horizon is reached. Here viscous stresses that favor magma ponding result from the dilational volume change associated with magma freezing. All crustal accretion in rocks cooler than a magma 'solidus' is assumed to occur in a narrow 250m-wide dike-like region centered about the ridge axis in order to model the the steady state thermal impact of crustal accretion via dike injection and pillow flows. The emplacement of the rest of the oceanic crust is modeled as a steady state magma lens directly beneath the 'solidus' freezing horizon. The difference between crustal thermal structures at fast and slow spreading ridge axes results from a fairly delicate balance between magmatic heat injection during crustal accretion and hydrothermal heat removal.
