矿区内岩石化学测量也证明:盆地内发育的内碎屑堆积硅质岩比周围岩石具有更高的Cu、Ag元素地球化学丰度值,Cu元素分布的显著不均一性,表明了后期构造的改造作用。
Ore area petrochemistry analyse also prove : intraclast congeries silica rock in basin have higher Cu , Ag abundance than circumference pena . The prominence inhomogeneity of the Cu distribution indicates reconstruct of the late construction .
