Probe into the genesis and metallogenic model of Lizigou Gold Deposit in Songxian County,Henan Province

The paper has proposed that the deposit is classified to be the low to moderate temperature hydrothermal structural altered rock-host gold deposit,and occurred below the strata of Xiong'er Group volcanic rocks through analysis of,research on and calculation of metallogenic material sources of Lizigou gold deposit,metallogenic material,metallogenic temperature,and metallogenic depth and metallogenic pressure of gold.The local abnormality of Yanshanian concealed rock body leads to heating the formation water,with extraction of gold from volcanic and formation of ore-bearing hydrothermal solution.Then after the process of structure-depressurization-flash and precipitation,the deposit has been formed and three magmatic tectonic hydrothermal migrated precipitate metallogenic models has been set up(the shape of ginseng,the shape of Chinese character Fei,the shape of branch).
