Geochemistry study of uranium and other element in brown coal of ZK0407 well in Yili basin

The geochemical behavior of 59 constant and trace elements in brown coal of ZK0407 well located at Honghaigou area in Yili basin of Xinjiang, China, was examined by mathematical statistics methods. It is showed that the elements in ash is opposite number with those in inherent moisture and in fixed carbon, and has synchronous changes with those in volatile matter. ZK0407 well has been located at interlayer oxidation zones and was uranium bonanza in geological history. Now, it is the wing of mineralization under interlayer oxidation zone. Uranium maybe mainly exist in the pore of brown coal and clay fraction in coal by manner of physical adsorption.
