Jinshan gold deposit locates in Dazhuangzi-Jinshan-Xiaozhuang ductile brittle shear zone in north Qixia city，which is closely associated with basic vein rock in Mesozoic era.The fluid inclusions show that the ore-forming fluids are of low salinity and low-density NaCl-H2O-CO2 system characterized by rich CO2 in the early stage of mineralization.But after boiling action，it later becomes to be NaCl-H2O system formed at 2.33~3.00 km below the surface with a temperature of 165~280 ℃.Isotope studies show that the ore-forming fluids is mainly from magmatic water in the early stage of mineralization and much meteoric water were mixed into the ore forming system during the late stage，metallogenic materials originate from dikes of Mesozoic，and also from palanobasement of Jiaodong.Changes of Physical and chemical properties caused by boiling action and mixture of atmospheric precipitation is main metallogenic mechanism.
