The sulfide deposits have three- dimensional texture feature of "massive ore sheet plus stratabound network ore zone". Massive ore sheets show polycyclic rhythmicity of sulfide + sulphate, suggesting that the hydrothermal fluids were discharged episodically on seafloor, and sulfides and sulphate were both deposited chemically in brine pools and accumulated through collapse.
