Περίληψη
Στο υπέρ-υψηλών πιέσεων μεταμορφικό σύμπλεγμα της Κύμης απαντούν γρανατούχοι-σπινελιούχοι μεταπεριδοτίτες με διαστρώσεις κλινοπυροξενιτών. Τα γεωχημικά χαρακτηριστικά κύριων στοιχείων και ιχνοστοιχείων και η προσομοίωση των κύριων στοιχείων έδειξε ότι οι περιδοτίτες αποτελούν υπολειμματικά πετρώματα που προήλθαν από κυμαινόμενο βαθμό αδιαβατικής τήξης του μανδύα. Οι κλινοπυροξενίτες αποτελούν υψηλών πιέσεων, πλούσια σε κλινοπυρόξενο σωρειτικά πετρώματα, τα οποία πιθανώς σχηματίστηκαν στο πεδίο σταθερότητας του γρανατούχου και/ή σπινελιούχου περιδοτίτη.
