Sellaite-quartz vein-type gold deposit.
The Pianyanzi deposit (>5 t Au @ 2.5 g/t) is located 6 km north of Kangding City in western Sichuan Province, Southwest China. It has a long history of sporadic mining dating back ∼ 100 years, but the amount of Au ores extracted during the early period is unknown, and therefore the size of the deposit has been underestimated.
The exposed strata of the Pianyanzi deposit mainly consist, from oldest to youngest, of the Ediacaran Doushantuo and Dengying Formations, the Silurian Maoxian Group, and the upper Triassic Hanfengya Formation. The Doushantuo Formation is exposed in the southeastern part of the mining area and is mainly composed of fine-grained limestone. The Dengying Formation can be divided into two units: (1) the lower unit of fine-grained dolomitic limestone; and (2) the upper unit of fine-grained dolomite and algal-rich dolomite. The upper unit of the Dengying Formation hosts the gold ore bodies. The Maoxian Group comprises crystalline limestone, slate and phyllite, which are exposed in the western part of the deposit. The Hanfengya Formation crops out in the southeast corner of the deposit and consists of sericitic phyllite interbedded with sandy slate.
