Η προέλευση της μεταλλοφορίας βαρύτη του γρανίτη της Μυκόνου : Ισοτοπική έρευνα ρευστών εγκλεισμάτων

Χατζηπαναγιώτου, Χρήστος 11 October 2013 (has links)
Γνωρίζουμε ως δεδομένο ότι το κεντρικό Αιγαίο έχει υποβληθεί σε ηπειρωτική διαστολή κατά το Ολιγόκαινο. Κατά το στάδιο της διαστολής είχαμε διείσδυση ενός γρανιτικής σύστασης πλουτωνίτη οποίος σχετίζεται με το σύστημα αποκόλλησης της Μυκόνου. Η Μύκονος κυριαρχείται από έναν μονζογρανίτη, Ι-τύπου, η ηλικία του οποίου είναι περίπου 10Μa όπως υποδεικνύεται από τα θερμοχρονολογικά δεδομένα, ο λακκόλιθος της Μυκόνου είχε εκταφεί πολύ γρήγορα. Ο λακκόλιθος της Μυκόνου διείσδυσε στην κατώτερη ενότητα και έχει μονζογρανιτική έως γρανοδιοριτική σύσταση και υπέρκειται από ένα σύστημα μικρής κλίσεως ρηγμάτων. Η αποκόλληση της Λιβάδας η οποία ήταν ενεργή ταυτόχρονα με την εκταφή του γρανίτη με αποτέλεσμα τη δημιουργία μίας μικρής κλίσεως εύπλαστης διατμητικής ζώνης η οποία επαναενεργοποίησε την επαφή διείσδυσης του γρανίτη μεταξύ του μεταβασίτη και της ανώτερης ενότητας. Η κύρια απόθεση του βαρύτη έγινε σε περιοχές στις οποίες παρατηρείται μεγάλη παρουσία ρηγμάτων. Από τα δείγματα τα οποία συλλέχθηκαν από την περιοχή του Πανόρμου απομονώθηκαν ρευστά εγκλείσματα μέσα από διαφανή ορυκτά όπως ο βαρύτης και ο χαλαζίας και χρησιμοποιήθηκαν για την ισοτοπική ανάλυση. / We know as a fact that the central Aegean domain has undergone continental extension during the Oligocene. The extensional stage was accompanied by the intrusion of granitic plutons and associated detachments, such as the Mykonos and Livada detachments. Mykonos Island is dominated by an I-type monzogranite. The age of the monzogranite is about 10Ma and as indicated by the thermochronological data, Mykonos laccolith was exhumed very fast. Mykonos laccolith intruded into the Lower Unit and has a monzogranitic to granodioritic composition and are topped by a low angle normal fault system. Livada detachment, which was active along with the exhumation of the granite, corresponds to a low-angle ductile shear zone that reworked the intrusive contact of the granite within the metabasites of the upper plate and has undergone through intensive mylonitization and brecciation. Where the faults are most highly concentrated, they are mineralized with barite and iron sulphides with local concentrations of argentiferous galena and sphalerite. The barite vein system which is deposited in the area of Panormos Bay is hosted in the monzogranite and consists of a set of ten major NW- to NNW- crustified tension gashes filled with barite and other minerals. Sample material that was collected from Panormos Bay was used for the study of fluid inclusions that were trapped in coarse-grained transparent minerals such as barite and quartz. Looking at fluid inclusions trapped within minerals can provide very useful information about as part of a target selection process and the conditions existing during the formation of barite as well as the origin of the mineralization on Mykonos Island.
