tra two-dimensional kinematic models of basin subsidence. The results demonstrate that, compared to models in which density is solely temperature dependent, phase transitions have the effect of increasing post-rift subsidence while decreasing syn-rift One of the most widely used models for subsidence of sedimentary basins formed by exten-and by thermal cooling [1]. An important feature of the USM formulation is that lithospheric density is assumed to depend only on temperature, a model we Earth and Planetary Science Letterssubsidence. Discrepancies between our model results and those obtained with the conventional uniform stretching models can be up to 95 % for reasonable parameter choices. The models also predict up to 1 km of syn-rift uplift as a consequence of phase transitions. Mantle phase transitions, in particular the spinel–garnet–plagioclase–lherzolite transitions are responsible for the most significant effects on subsidence. Differences in mantle composition are shown to be a second-order effect. Parameterize
