四道沟金矿褶皱构造叠加对金矿的控制作用

The controlling effect of the superimposition of folded structural systems on Si Dao Gou Gold Deposit

四道沟金矿床产于震旦系辽河群中低级变质岩系中，矿床主要受东西轴向的褶皱构造控制。南北轴向的褶皱构造与东西轴向的褶皱构造相互叠加，形成了格子状构造，控制着金矿的主体。针对两期褶皱构造体系叠加对金矿的控制作用，指导找矿方向，具有十分重要的意义。

Si Dao Gou Gold Deposit occurred in medium low grade metamorphite system of Liaohe group,Sinian System.The ore deposit is controlled mainly by east west axial folded structure.The superimposition of north south axial folded structure and east west axial folded structure forms lattice structure and controls the main part of the gold ore deposit.The controlling effect of the superimposition of two type folded structural systems on gold deposit provides guiding significance for determining ore prospect orientation.
