The distribution of trace elements in Turkish lignites in Western Anatolia and the Thrace Basin
The United States Geological Survey (USGS) and the General Directorate of Mineral Research and Exploration in Turkey (Maden Tetkik ve Arama:MTA) are working together to provide a more complete understanding of the chemical properties of lignites from major Turkish lignite producing areas. The project is a part of the USGS effort to produce an international coal database and is part of the ``Technological and Chemical properties of Turkish Lignite Inventory Project'' being conducted by the MTA General Directorate. The lignites in Turkey formed in several different depositional environments at different geologic times and have differing chemical properties. The Eocene lignites are limited to northern Turkey. Oligocene lignites, in the Trace Basin of northwestern Turkey, are intercalated with marine sediments. Miocene lignites are generally located in western Turkey. These coal deposits have relatively abundant reserves, with limnic characteristics. The Pliocene-Pleistocene lignites are found in the eastern part of Turkey. Most of these lignites have low calorific values, high moisture and high ash contents. The majority of the lignite extraction is worked in open-pit mines. Turkish lignite production is used mainly by power plants; small amounts are used by households and in industry. All the samples in this study were collected as channel samples of the beds. Analyses of 71 coal samples (mostly lignites) have been completed for 54 elements using various analytical techniques including inductively coupled plasma emission and mass spectrometry, instrumental neutron activation analysis and various single element techniques. Many of these lignites have elemental concentrations similar to those of US lignites. However, maximum or mean concentrations of B, Cr, Cs, Ni, As, Br, Sb, Cs and U in Turkey were higher than the corresponding maximum or mean found in either of the Fort Union or Gulf Coast basins, the two most productive lignite basins in the U.S.
