Ore Control Factors and Prospecting of Gubang Gold Mining Area

By study the ore factor,stratum,structure and lithofacies palaeogeography of Gubang gold mining area,it's thought that Changan formation of Nanhua system which gold content is high,affords some material source for gold mineralization.The gold mineralization is tectonic altered rock and quartz vein type gold deposit.Changan formation of Nanhua system in this area is a series of interglacial deposit during ice age.The stratum lithology is exclusive for the gold mineralization in this area,the tectonic altered belt of fracture structure which developed in the cleavage concentrated zone controls the distribution of gold mineralization zone.The concentrated steep baroclinic shear joint controls the occurrence of quartz vein fold deposit.The tectonic altered zone and joint contrated zone has deep relation of gold mineralization,controls the positioning of this kind of gold ore body.
