Habo gold deposit was located in Changdu-Lanping-Simao folded series in Yuanyang County, Yunnan Province.The orebodies were mainly buried in tectonic zone of fracture of Waigucun Formation, the tectonic fracture zone of NWW-SEE strike was the migration channel and ore-hoisting place of mineral materials.The volcanic sedimentary rocks of Waigucun Formation were the major source beds, and the intensive tectonic shearing and magmatism supplied thermal fluid for ore mineralization.Based on the analyses of regional geology and geological properties of the deposit, the authors concluded that Habo gold deposit belonged to a kind of sedimentary altered gold deposit.
