Jurassic volcanism in the western Tethys (Iberian Range, Spain): geological maps

Occurrences of interbedded volcanic deposits in the Jurassic marine carbonate successions of the SE Spanish Iberian Range (Iberian Plate) have been reported since the 1930s. However, it was not until now, almost 85 years later, that these volcanic deposits have been quantified and dated. Eight sites...
