The Jingbian ore deposit is a medium-low temperature hydrothermal type Cu (Au) deposit lying in central Luzong Basin.  The ores are mainly in the veinlet, stockwork, crystal aggregate forms with subordinate brecciated structure.  The textures of the ore are complex, resulting from metasomatism and crystallization.  The ore bodies are commonly steeply-dipping veins, controlled by fault structure and tectonic shatter zone.  The typomorphic values of Co/Ni, Fe/(S+As), and S/Se of pyrite show that the hydrothermal ore-forming solution mainly came from medium-low temperature magmatic hydrothermal fluids.  The overall REE characteristics are similar to those of chalcopyrite from the Jingbian copper (gold) deposit, Bajiatan intrusive rock and volcanic rock and subvolcanic rocks of Zhuanqiao Formation.  The REE characteristics of chalcopyrite inherited or retained source characteristics of ore-bearing magmatic rocks.
