Κοιτάσματα τύπου skarn = Skarn deposits.
Περίληψη
στην ταξινόμησή του ανάλογα με τις εκάστοτε συνθήκες σχηματισμού που επικρατούν και τα χαρακτηριστικά του.
Ο συγκεκριμένος τύπος κοιτάσματος έχει μεγάλη οικονομική σημασία, καθώς αποτελεί αντικείμενο εκμετάλλευσης πληθώρας χρήσιμων χημικών στοιχείων.
Στην συνέχεια γίνεται αναφορά στην ορυκτολογία και την γεωχημεία των skarn και στο πώς κατατάσσονται βάση αυτών των χαρακτηριστικών.
Αναλύεται η έννοια της μετασωμάτωσης επαφής και της διαδικασίας της διάχυσης και διήθησης που είναι υπεύθυνη για την γένεση των κοιτασμάτων skarn
σε συγκεκριμένα τεκτονικά περιβάλλοντα, καθώς και οι αναγκαίες συνθήκες για τον σχηματισμό τους, αλλά και η εξέλιξη των συγκεκριμένων κοιτασμάτων skarn.
Τέλος αναφέρονται κάποια σημαντικά κοιτάσματα skarn στην Ελλάδα αλλά και στον υπόλοιπο κόσμο.
The present diploma thesis refers to the skarn mineral deposits.
Special reference is made to the definition of the term skarn and to the classification of the deposits according to their characteristics
and the prevailing conditions of formation. This deposit type is economically valuable because of the large variety of chemical elements that includes.
Special reference is made to the mineralogy and geochemistry of skarn deposits and their classification based on them. The definition of metasomatism,
the progress of diffusion and filtration which is responsible for the genesis of skarn deposits at specific tectonic environments,
the formation conditions and the evolution of skarn deposits, are discussed in details.
Finally, some important skarn deposits from Greece and worldwide are described.
