Neogene Achlada lignite deposits in NW Greece

Abstract: Preliminary macro-petrographical analyses of samples taken from late Miocene (Pontian) to early Pliocene/Pleistocene lignite deposits at Achlada, northwestern Greece, show that there are two units in the lower 10 m of the lignite-bearing sequence. From 0 to 3.20 m a mixed xylite-rich /matrix lithotype is dominant and from 3.20 to 10 m a matrix-dominated lithotype is prevalent. The layers consist of organic and inorganic cyclical alternations with intercalated typical xylite horizons. The first results of coal … Show more

“…All these basins began forming in Late Miocene time. The lithostratigraphic units of Ohrid, Prespa and Dibra basins are correlated with the respective lithostratigraphic data of such basins partly developed in southern North Macedonia close to the border, as well as with the stratigraphic data from Florina-Ptolemais graben basin in Northwestern Greece (Pavlides and Mountrakis, 1987;Iordanidis et al, 2003;Steenbrink et al, 2000;2006;Metaxas et al, 2007;Oiconomopoulos et al, 2008) (Fig.2). The stratigraphic data for the Piskupstina, Prespa and partly Peshkopi graben basins are shortly described below based on the data of Dumurdzanov et al (2004).…”

“…as Pliocene in age is indeed Late Miocene (Dumurdzanov et al, 2004;Krstic et al, 2012). On the other hand, the stratigraphic successions of the Florina-Ptolemais Basin in NW Greece belong to Late Miocene (Pontian sensu lato) to early Pliocene (Pavlides and Mountrakis, 1987;Steinbrink et al, 2000Steinbrink et al, , 2006Iordanidis et al, 2003;Metaxas et al, 2007;Oiconomopoulos et al, 2008).…”

“…Approximately 64 Mt of lignite, produced by open-cast mining in four mines, are annually used in the pulverized lignite-fired power stations (Kavouridis, 2008). Several studies have been published on the petrography of Greek lignites, most of them focused on the large lignite deposits of the broader Florina-Ptolemais-Kozani area (e.g., Kalaitzidis et al, 2004;Mavridou et al, 2003;Antoniadis et al, 2006aAntoniadis et al, , 2006bOikonomopoulos et al, 2008). Nevertheless, not all of the lignite sequences of the area have been studied in detail.…”

“…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.
