ABSTRACT
New two-dimensional (2-D) thermomechanical finite-element models are used to test whether thrust advection, particularly at normal (10–20 km m.y.‒1) to high (>50 km m.y.‒1) horizontal slip rates, can substantially influence relatively high metamorphic heating rates (150–250 °C m.y.‒1). Simple beam models that involve a single thrust with a dip of ~30° and geothermal gradients that are initially equal in the hanging wall and footwall yield maximum footwall heating rates of 15, 32, 75, and 150 °C m.y.‒1 for imposed thrust rates of 5, 20, 50, and 100 km m.y.‒1 (5–100 mm...
