The Bailugou lead-zinc deposit, a newly-discovered ore deposit in Luanchuan area, Henan Province, is well-known for its porphyry-skarn type molybdenum ore bodies.  It is hosted in the west limb of the Niuxinduo dome-like anticline, and is adjacent to the Nannihu, Sandaozhuang, Shangfanggou and Majuan porphyry-skarn type molybdenum deposits in the area. Using the pressure of the peak homogenization temperature (38.94 MPa to 44.87 MPa), the authors estimated that the mineralization depth lies between 1.44 km and 1.66 km.  It is thus held that mesothermal temperature, low salinity and shallow mineralization depth characterize the Bailugou lead-zinc deposit.  It suggests that the metallogenic metals were mostly derived from porphyries in the area with the participation of a certain amount of stratigraphic metals.  The Bailugou lead-zinc deposit is a magmatic mesothermal filling-metasomatic type ore deposit controlled by interlayer fractures.
