Geological Evolution - Stratigraphy of Florina, Ptolemaida, Kozani and Saradaporo Graben

Abstract

The purpose of this research is to comprehend the geological and stratigraphical evolution of Fiorina, Ptolemaida, Kozani and Sarandaporo graben. This graben ex tends North of the Greek borders and is more than 150

Contribution of Lignite in the Greek Economy

“…In Greece, lignite formation started during Eocene and continued to date (Metaxas et al, 2007). A schematic representation of the general creation way of lignite is given in figure 6, while in figure 7 is schematically given the creation of the lignite-bearing basin Kozani -Servia.…”

Co2 Content of Greek Lignite: The Case of Proastio Lignite Deposit in Ptolemais Basin, Northern Greece

“…It is a discontinued geological unit due to occurrence of recent tectonic disturbances of great scale, which were activated in Neogene and Quaternary times. The elongated and deep basins (Metaxas et al, 2007) of Ptolemais-Ardasa-Vegoritida, etc. as well as the tectonic ridges of Xyno Nero, Bordo-Filota, etc., disrupted the continuity of various lignite-bearing regions (Fig.…”

“…The stratigraphic structure of the sedimentary series, the lithofacies analysis of the geological formations and the geological structure of the lignite deposits in general, were based on the data obtained from the study of borehole cores (Kotis et al, 2001). The overview of the geological setting of the broad Ptolemais basin (Metaxas et al, 2007) is showing in the stratigraphic column (Fig. 2).…”

“…Small amounts of carbon dioxide are emitted from volcanoes and other geothermal processes such as hot springs and geysers and by the dissolution of carbonates in crystal rocks. The Pliocene lignite deposits hosted in the Ptolemais Basin display high CO 2 contents (Metaxas et al, 2007) resulting in the emission into the atmosphere of 0.6-0.7 t CO 2 per ton of lignite burned in the thermal power plants. A representative deposit of this age is that of Proastio, which, in terms of total reserves, is the second one after the Southern Field deposit.…”

Ορυκτολογική Ανθρακοπετρογραφική Και Παλαιοβοτανική Έρευνα Του Λιγνιτικού Κοιτάσματος Αχλάδας Ν. Φλωρίνης

“…Ο μεγαλύτερος όγκος των εργασιών μέχρι σήμερα, που αναφέρεται στα ελληνικά λιγνιτικά κοιτάσματα, σχετίζεται με τη μελέτη της ανθρακοπετρογραφικής σύστασης λιγνίτη και ξυλίτη, όπως επίσης και της παλαιοβοτανικής σύστασης αυτών, με στόχο την ερμηνεία του παλαιο-περιβάλλοντος σχηματισμού τους. Ενδεικτικά αναφέρονται ορισμένες εργασίες που αφορούν τόσο στην ανθρακοπετρογραφική (π.χ Kalaitzidis et al, 2003, Παπαζησήμου, 2003, Diamantopoulos et al, 2004, Μπουζίνος, 2004, Μπουζίνος και Ιωακείμ 2004, Siavalas et al, 2004, 2005a,b, 2006a,b,c, Samara, 2005, Tsikritzis, 2005, Koukouzas, 2007, Μαυρίδου, 2007, Metaxas et al, 2007, Oikonomopoulos et al, 2008, όσο και στην παλαιοβοτανική σύσταση των ελληνικών λιγνιτικών κοιτασμάτων (π.χ Shneider and Velitzelos 1973, 1977, Velitzelos and Schneider 1979, Velitzelos et al, 1981, Gregor, 1982, Ioakim and Velitzelos, 1983, Gregor and Velitzelos 1984, Ioakim, 1985, Riegel et al, 1988, Kaouras, 1989, Velitzelos and Gregor, 1990, Αντωνιάδης και Μαυρίδου, 2004, Oikonomopoulos et al, 2007. Επίσης ο Christanis (2003) δημοσίευσε μια εμπεριστατωμένη μελέτη σχετικά με τις έρευνες που έχουν πραγματοποιηθεί στα ελληνικά λιγνιτικά κοιτάσματα.…”
