Polymetallic volcanic-hosted metasomatite, consisting of more than 40 veins that occur along NW-striking fractures. The wallrock is a complicated sequence of Late Permian volcanoclastic rocks of the Laolongto Formation, intermediate to mafic volcanic rocks of the Late Jurassic Tamulangou Formation, intermediate to siliceous volcanic rocks of Late Jurassic Shangkuli Formation, Variscan granite, and Mesozoic diorite porphyry, feldspar, as well as quartz porphyry and beschtauite. Alterations are silica, chlorite, carbonate, sericite, fluorite, epidote, and hydromica. The deposit occurs in a Variscan orogenic belt between the Siberian and North China Platforms.
