Permian <sup>40</sup>Ar/<sup>39</sup>Ar ages for post-Variscan minor intrusions in the Iberian Range and Spanish Central System

40Ar/39Ar dating of biotite from a calc-alkaline gabbro stock NW of Loscos in the Iberian Range yielded a slightly disturbed gas release spectrum. It has an early Permian, 288.5 ± 1.4 Ma total gas age, interpreted as the minimum emplacement age. The 40Ar/39Ar apparent age of the gabbro agrees with t...
