Geological Characteristics and Ore Propects of Zinc-Fluorite Deposit in Pingli Damogou, Shaanxi

PingliDamogou zinc-fluorite depositin in Shaanxi and metal minerals of gold,lead,zinc,niobium and tantalum and nonmetal mineral fluorite,etc,already found in this region,have a close relation ship with the trachyte in this area and neighbor area.Mineralization is in contact with faulting of Middle Silurian Zhuxiqun Formation phyllite and trachyte,and is near the trachyte side and controlled by faulted structure,belonging to post-magmatic hydrothermal ore deposits.Regionally,alarge area of rachyte exposed to the eastwing of Pinglian ticlinorium results in numerous ore-hosting rocks for minerals,having animportant significance in prospecting.
