There are over 300 coal basins and deposits known in Kazakhstan, the largest of them is the Karaganda Coal Basin. There is approximately a half of all industrial reserved of coal of Kazakhstan is located in its subsoils. The Karaganda Coal Basin is the forth in the CIS according to its size and coal reserves. Unique coal resources require a comprehensive and scientifi cally justifi ed approach to their research. This paper studies the impurity elements distribution pattern to assess the geochem- ical speciation of coals in the Karaganda Coal Basin. As a result of the research performed, it has been found that the basin is characterized by mainly lithophylous and weal chalcophilous (Te, Cu, Ga, Ge) speciation. Siderofylous association is represented by Co, Ag. In the basin coal, increased concentrations of Ba, Sr, U, Sm, As, Sb, Fe, Br, La, Ce, Th, Cr, Hf, Cs, Co, Sc are detected if compared to the coal clarke, which is conditioned by the provenance area of the coal accumulation basin.
