Περίληψη

Σκοπός της εργασίας αυτής είναι να εξετασθεί η μεταμόρφωση υπερ-υψηλής θερμοκρασίας. Στο πρώτο μέρος δίνεται μια γρήγορη εισαγωγή για τα μεταμορφωμένα πετρώματα σχετική με τους παράγοντες που επηρεάζουν την μεταμόρφωση, την ταξινόμηση των μεταμορφωμένων πετρωμάτων, τις αλλαγές κατά την μεταμόρφωση καθώς και τα είδη της μεταμόρφωσης. Στο δεύτερο μέρος αναλύεται η μεταμόρφωση υπερ-υψηλής θερμοκρασίας, οι μέθοδοι προσδιορισμού των συνθηκών της μεταμόρφωσης, οι πηγές θερμότητας καθώς και το γεωτεκτονικό περιβάλλον στο οποίο εμφανίζεται. Τέλος, δίνονται οι τοποθεσίες όπου έχουν βρεθεί πετρώματα υπερ-υψηλής θερμοκρασίας, όπως στην Νότια Ινδία, στην Σρι Λάνκα, στην Κεντρική Βραζιλία και στην Ινδονησία.

The aim of this Bachelor thesis is to examine ultra-high temperature metamorphism. The first part gives a quick introduction to metamorphic rocks related to factors affecting metamorphism, classification of metamorphic rocks, changes during metamorphism and types of metamorphism. In the second part, ultra-high temperature metamorphism is analysed, as well as the methods used to determine the metamorphic conditions, the sources of heat and the geotectonic environment in which ultra-high temperature metamorphism occurs. Finally, the locations where ultra-high temperature metamorphism occurs are reported, South India, Sri Lanka, Central Brazil and Indonesia.
