Replacement-type gold-pyrite mineralization associated with jasperoid development and decalcification, occurring in limy horizons and along bedding planes within the transitional zone from older carbonate rocks to overlying younger sandstones and siltstones. Higher-grade mineralization is concentrated in areas of intersecting northwest and northeast fracture zones along the crest of the N-S trending Xianrenyan Anticline, and is also associated with magnetite skarn alteration developed in granodiorite dike swarms. Silicified rock exhibiting multiple stages of brecciation and epithermal-type veining is common, and an alteration halo consisting of clay and carbonates surrounds the mineralized zone.
