DISTRIBUTION OF MAJOR OXIDES AND TRACE ELEMENTS CONCENTRATION OF MANCILIK (G?NEN – BALIKESIR) COAL DEPOSIT

摘要

Coal is clearly important for Turkey, with over half of electric generation provided fromfossil fuels (coal and natural gas). Therefore, large amounts of various trace elementsare isolated every year with the coal ash. Coal`s trace element concentration is gettingmore important in terms of environmental, economic, by-product, and technologicalbehavior of coals and their effects on public health.The investigation is focused on trace elements in Manc?l?k (G?nen) coal deposit, BigaPeninsula, NW Turkey. The basement of the region, which consists of the Paleozoic -Mesozoic metamorphic rocks (mainly of gneisses, amphibolites, marbles, andmetaophiolites) and crystallized limestone, is in the subsurface near the Manc?l?k coalfield. The Tertiary volcanics are andesitic, dacitic, and rhyodacitic. The Miocene coalswere deposited and alternated with volcanic-sedimentary rocks, which consists ofsandstone, conglomerate, claystone, bituminous shale, agglomerate, and tuff.The coal occurrence was sampled and analyzed. The analyses were correlated andinterpreted with the previous studies. Chemical investigations were performed on thecoal ashes via XRF and ICP-EAS methods at University of Kentucky Center forApplied Energy Research’s laboratories.The trace element analyses show that As, Ga, and U are significant enriched in thesamples. The contents of Mo, Pb, V, Rb and Sb are also higher than world coals. Theabundance of the investigated trace elements can lead to cause some environmentalproblems and related disease, factors which should be considered in the usage potentialof the coals.
