High sulphidation type epithermal gold deposit, related to breccias occurring along the southern margin of the Hongliuhe fault zone. Gold mineralizations occur in quartz veins, in veinlets and as disseminations in altered rocks, hosted by late Paleozoic sedimentary rocks and related to a Hercynian granitoid intrusion.

Geochronology

Mineralization age: Middle Triassic : 242.8 ± 0.8 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
