AB This work constitutes a combination of morphological and geochemical results of zircon populations oftwo typical lithologies from the Ollo de Sapo Domain in the Sanabria complex: augengneiss and schist.The combination of these methods allows us discriminating between the discussed plutonic or volcanosedimentaryorigin of Ollo de Sapo rocks. Results allow the assignment of a peraluminous porphyriticgranite derivated from a polygenetic source as protolith of the gneiss. Zircons from the schist are morevaried and their characteristics point to a volcanosedimentary protolith constituted by mainly calc-alkalinecrystals. Moreover, the morphological and geochemical study of an enclave of gneis in monzodioriteshows there are at least three populations of zircons in this sample. Therefore, these methods result to beuseful in order to separate different zircon populations that could be wrongly considered together ingeochronological studies
