Resumen

A batholith of around 10,000 km
2
was formed during the Hercynian orogeny in the
Spanish Central System (SCS). Geochronological data indicate concentrated magmatic activity
during the period 325-284 Ma. This late-orogenic magmatism is essentially granitic with only
minor associated basic rocks « 2% in outcrop). The SCS is a remarkably homogeneous batholith
showing a restricted range of geochemical granite types without any evolutionary pattern
related to time. These peraluminous granites show a limited variation in Na20/K20) (0·6
