摘要: 排山楼金矿赋存于太古宇建平群片麻岩与元古宇长城系大红峪组砂岩、高于庄组白云岩之间的东西向韧性剪切带中,为大型同韧性剪切带型金矿床.在排山楼金矿南带十家子一带发现,与排山楼金矿赋存于相应层位中的含金韧性剪切带层序倒转,含金韧性剪切带层位由处于高于庄组白云岩层之下变为在白云岩层之上,找矿方向和重点由此发生了根本改变.Abstract: The Paishanlou gold deposit occurs in the E-W-trending ductile shear zone between the Archean gneiss and Proterozoic sandstone and dolomite. Geological survey found that the stratigraphic sequence of the gold-bearing ductile shear zone in the southern belt of the gold deposit is reversed. That means the ore-bearing horizon is located on the dolomite formation, instead of under it. This understanding leads to a complete change of prospecting direction and stress.
