%X A batholith of around 10,000 km2was formed during the Hercynian orogeny in theSpanish Central System (SCS). Geochronological data indicate concentrated magmatic activityduring the period 325-284 Ma. This late-orogenic magmatism is essentially granitic with onlyminor associated basic rocks « 2% in outcrop). The SCS is a remarkably homogeneous batholithshowing a restricted range of geochemical granite types without any evolutionary patternrelated to time. These peraluminous granites show a limited variation in Na20/K20) (0·6
