Abstract: Baerluke Mountain is located in the western margin of west Junggar. There is a nearly east-west ophiolite melange belt named Yejiebai in southwest Barluke Mountain. The basic-ultrabasic rocks were well-developed in the belt. Lots of gold anomaly and mineralized body have been discovered in the basic-ultrabasic rock and the surrounding rock. Existing work and prospecting practice show that the spatial occurrence of gold mineralized body is closely related to basic-ultrabasic rock in the west of Yejiebai ophiolite melange belt and the orebody characteristics are similar to the typical basic-ultrabasic rock type gold deposits. By studying the metallogenic theory of basic-ultrabasic rock type gold deposits, combined with the characteristics of mineralization bodies, metallogenic conditions, geophysical and geochemical features, and ore-forming regularity, the authors hold that the contact zone with well-developed serpentinization of basic-ultrabasic rocks and their south-north wall rocks, basic-ultrabasic rock with well-developed tectonic and serpentinization, the ductile shear zone in the ophiolite mélange and the structural position nearby are all favorable mineralization regions. The basic-ultrabasic rock type gold deposits are prospective in the eastern Yejiebai ophiolite melange belt and Suyunhe ophiolite melange belt.
