Abstract: Maoling gold deposit is discovered in 1980s,it is the oversize gold deposit in the rift valley of Liaoning and Jinning province,and the characteristics of the gold deposit is multi-stage,low grade and large reserves.The stratum of the gold deposit is belongs to Gaixian group of Paleoproterozoic liaohe group,besides that,the stratum of the gold deposit is the ore rock.The Mesozoic Wolongquan orebody and Maoling orebody are the main orebody in the mine area,and they are similar with each other.Wolongquan orebody has the close relationship with ore-forming.The mining structure is divided into Lvliang toughness-plastic structure and brittle fracture structure since the Mesozoic era.Maoling gold deposit can be divided into three metallogenic belts,Development of the first metallogenic belt that the No.9 orebody is located is best and the reserves of the first metallogenic belt is largest of all the metallogenic belts.Type of the ore-bearing hydrothermal is CO2+NaCl+H2O , and the chracteristics of the ore-bearing hydrothermal are low salinty,low degree of mineralization and acidity are analyzed by the analysis on S,Pb,H-O,C-O and ore primary fluid inclusions.According to the analysis results,the temperature of the ore-beraing hydrothemal is determined to 153~391 ℃,the ore-forming age is less than 192 Ma.Maoling gold deposit is regarded as the metamorphic tempreature veinlet disseminated type hydrothermal gold deposit,and the metallogenic model of it is summarized.
