Thrust geometry and the location of gneiss domes: implications of thermal models of the Central Iberian crustal domain during the Variscan
England and Thompson (1984) and Peacock (1989) developed a method to produce thermal models of the pressuretemperature-time (P-T-t) paths of regional metamorphism in thickened continental crust. Their models place the physical conditions undergone by rocks initially at different depths in a temporal...

| Sumario: | England and Thompson (1984) and Peacock (1989) developed a method to produce thermal models of the pressuretemperature-time (P-T-t) paths of regional metamorphism in thickened continental crust. Their models place the physical conditions undergone by rocks initially at different depths in a temporal frame and permit a better understanding of the orogenic processes involved. One common response to thickening that is observed in orogenic belts is the formation of gneiss domes (Whitney et al., 2004). Gneiss domes are an important feature of the Iberian crust affected by the Variscan orogeny and are abundant in the core of the Central Iberian arc (Martínez Catalán, 2011). Recent investigations (Rubio Pascua,l 2012) in the Central Iberian zone (CIZ) provide data that can be used to constrain thermal models and to evaluate the model response to changes in basic parameters and in the geometry of structural evolution |
