Relationship Between Fractures And Preserving Disciplinarian Of Gold Deposit In The Eastern Bengbu Uplift

The work area located at the eastern Bengbu uplift and at the western Zhuding-Shimenshan fault which is a branch of Tan-Lu fault zone. It located at the southwest of Dagongshan.This article studys the characteristics of structures and disciplinarian evolvement in the work area, and analyzes the preserving mine in the area. The result indicates the primary folds which developed in the area is secondary structures of Bengbu anticlinaorium. There are many fractures in the area. After summing and analying there are 3 groups of faults. They are NNE-SN-trending faults, NWW-EW-trending faults and N-E-trending faults. The NNE-SN-trending faults are the primary faults. They pertain to Tan-Lu fault zone. Afer indagating the mine in the area, there is much metallic and nonmetallic ore deposits. The deposit is vien-hydrothermal type. The gold deposit is primay, and the baritic deposit is the secongdary. The result indicates there are two main types gold mineralization in the aire: quartz vein type and altered rock type. The mostly veins distributed along the trend of the faults in the field. The mineraling phenomena is much distinctness in the intersection of different trend of the faults.Summarizing the faults controlled the mine. The veins of gold mineralization controlled by NNE-SN-trending faults. The other trend of the faults controlled the mine, too. But the affection is less.
