Περίληψη


Στη παρούσα διπλωματική πτυχιακή εργασία πραγματοποιείται ποιοτική μελέτη του ορυκτού πλούτου των πολύτιμων λίθων στην Ελλάδα μέσω συστηματικής βιβλιογραφικής ανασκόπησης της διεθνούς βιβλιογραφίας. Η Ελλάδα, λόγω της τεκτονικής και γεωλογικής της σύστασης φιλοξενεί αρκετά κοιτάσματα πολύτιμων λίθων, τα περισσότερα εκ των οποίων εντοπίζονται σε μικρή έκταση. Από αυτά, κυριότερα είναι τα κοιτάσματα κορουνδίου, χαλαζία και αμέθυστου. Κοιτάσματα κορουνδίου, εντοπίζονται στις περιοχές της Ξάνθης, της Δράμας και στα νησιά της Νάξου και της Ικαρίας. Στη περιοχή της Ξάνθης εντοπίζονται ζαφείρια σε διάφορους χρωματισμούς, ενώ στην Δράμα ρουμπίνια με χρώμα που κυμαίνεται από ανοιχτό ροζ έως βαθύ κόκκινο. Η Νάξος και η Ικαρία είναι περιοχές με κοιτάσματα μπλε ζαφειριών. Ο χαλαζίας εντοπίζεται σε πολλές περιοχές όπως στην Αττική, τη Δράμα, την Εύβοια, την Ίο, τη Θάσο και την Κρήτη και σε διάφορες ποικιλίες. Από αυτές η μεγαλύτερη σε μέγεθος ποικιλία είναι ο αμέθυστος ο οποίος απαντάται σε περιοχές όπως στη Κορνοφωλιά του Έβρου, στις Σάπες της Ροδόπης, στη Λέσβο και τη Μήλο. Η αύξηση της συστηματικής έρευνας των πολύτιμων λίθων στη χώρα που καταγράφει τις ακριβείς ιδιότητες και τα χαρακτηριστικά τους, μπορεί να συμβάλει σημαντικά στην αύξηση της εξόρυξης και, κατ’ επέκταση, σε μια βιώσιμη και ανταγωνιστική οικονομία.

In this diploma thesis, a qualitative study of the mineral wealth in Greece is carried out through a systematic bibliographic review of the international literature. Greece, due to its tectonic and geological composition, is home to several deposits of precious stones, most of which are located in small areas. Of these, the most important are the corundum, quartz and amethyst deposits. Corundum deposits are found in the areas of Xanthi, Drama and the islands of Naxos and Ikaria. In the area of Xanthi, sapphires in various colors are found, while in Drama, rubies ranging in color from light pink to deep red. Naxos and Ikaria are areas with deposits of blue sapphires. Quartz is found in many areas such as Attica, Drama, Evia, Ios, Thassos and Crete and in various varieties. Of these, the largest variety is amethyst, which is found in areas such as Kornofolia of Evros, Sapes of the Rhodopes, Lesvos and Milos. Increasing the systematic research of precious stones in the country that records their exact properties and characteristics, can contribute significantly to the increase of mining leading to a sustainable and competitive economy.
