We use a thermomechanical modeling approach to study the development of extensional gneiss domes in a thickened and thermally relaxed lithosphere. Our models consider a compositional and thermally dependent rheological lithosphere layering, with a 60-km-thick crust and Moho temperatures in the range 840–1040 °C. No discontinuity or detachment fault is assumed to preexist within the upper crust. However, to initiate localized deformation, a density anomaly is placed at the base of middle crust. Extension is applied to one model boundary at constant rates of 2.0 and 0.66 cm/yr. Models illustrate the progressive development of domes and associated strain patterns at...
