Abstract: The Heishan-Qimantage metallogenic belt in the western section of east Kunlun Mountain, Xinjiang was recognized by recent geologic survey. The geologic condition for W and Sn metallogenic is discussed in the aspects of sedimentary formation, magmatic intrusion and tectonic activity. The prospecting targets for W and Sn deposits in this area are preliminarily delineated on the basis of 1:000 000 stream sediment surveying result, combining the metallogenic geologic condition.
