Early Permian skarn iron deposit of subvolcanic magmatic-hydrothermal filling (alteration) style, occurring in a rift on the southern margin of the Eastern Tianshan Mountains. The magnetite-rich garnet-diopside ore bodies are products of hydrothermal alteration. They occur in steeply dipping cracks in a diabase unit that contacts felsic schists to the north and gabbro to the south. Opencut mining has revealed that the ore bodies are intersected by multiperiodic diabase dykes trending in different directions.
