This article is a result of investigation oolitic iron ores from Bakchar deposit by: X-ray crystallography, simultaneous thermal analysis (STA), and a scanning electron microscope (SEM) combined with an energy-dispersive micro analyzer. The Bakchar iron ore deposit is located within the West Siberian iron ore basin, which is a large strip of the Cretaceous-Paleogenic littoral sediments with oolitic iron ores overlapped by a thick series (160-200 m) of the Neogene-Quaternary age [1]. The mineral composition of ores was studied in 1950-70s and described in many papers [2]. In 2005, mineral exploration and evaluation started again in the Bakchar deposit. As a result, large-scale works on defining geological composition of the deposit, and studying material composition of the oolitic iron ores were started. The oolitic iron ores were studied from one ore cut (Eastern part). The mineral composition includes many different minerals: terrigenous (quartz, feldspars, magnetite, ilmenite, zircon, rutile and many other), authigenic and clay (carbonates, glauconite, chlorite, goethite, hydrogoethite, lepidocrocite, phosphates, sulfides, and native silver) [3]. The most interesting minerals for studying genetics are clay minerals. This study was funded by the Russian Ministry of Education and Science, program "State consigning" and has been performed in the “Analytical center of geochemistry of natural systems” at National Research Tomsk State University.

Keywords: oolitic iron ore, glauconite, chlorite, kaolinite, illite
