Περίληψη

Γρανιτικά πετρώματα εμφανίζονται υπό μορφή κροκαλών στις φλυσχοειδείς αποθέσεις της ζώνης Παρνασσού, στην περιοχή της Οίτης (Κεντρική Ελλάδα). Πρόκειται για υπεραργιλικά, άσβεστο- (calcic) πετρώματα τα οποία παρουσιάζουν χαρακτηριστικά S-τύπου. Γεωχημικά δεδομένα υποδεικνύουν ότι τα πετρώματα αυτά δεν σχετίζονται γενετικά με το οφιολιθικό σύμπλεγμα της Οίτης αλλά προέρχονται από μάγματα που συνδέονται με διεργασίες καταβύθισης. Παρουσιάζουν χαρακτήρες γρανιτών ηφαιστειακού τόξου. Γεωχημικά προσομοιάζουν με γειτονικά γρανιτικά πετρώματα, τα οποία επίσης εμφανίζονται υπό μορφή τεμαχών στις περιοχές της Εύβοιας, της Αμφισσας και της Πάτρας
