Περίληψη


Τα κοιτάσματα skarn εμφανίζονται σε όλο τον κόσμο και έχουν γίνει αντικείμενο εκμετάλλευσης για διάφορα στοιχεία. Χωρίζονται σε επτά βασικές κατηγορίες οι οποίες είναι: σιδήρου, βολφραμίου, μολυβδαινίου, χαλκού, κασσίτερου, ψευδαργύρου και χρυσού. Ο σχηματισμός τους λαμβάνει χώρα σε ποικίλα βάθη και γεωτεκτονικά περιβάλλοντα. Τα skarn δημιουργούνται από την αντικατάσταση ανθρακικών πετρωμάτων μέσω διεργασιών περιοχικής μεταμόρφωσης ή μεταμόρφωσης επαφής και μετασωμάτωσης. Στον ελληνικό χώρο τα μεγαλύτερα κοιτάσματα skarn βρίσκονται στη Σέριφο, στο Λαύριο και στην Ξάνθη.

Skarn deposits occur throughout the world and have been exploited for various elements. They are divided into seven main categories including iron, tungsten, molybdenum, copper, tin, zinc and gold. Formation of skarns take place at various depths and geotectonic environments. Skarns are formed from the replacement of carbonate rocks through processes of regional or thermal metamorphism and metasomatism. In the Greek area, the largest skarn deposits occur in Serifos, Laurium and Xanthi.
