平度旧店金矿区同成矿构造与金的富集关系

Relation between Ore-forming Structure and Gold Concentration in Jiudian Gold Area in Pingdu City[JY。

摘要:

旧店金矿区有金矿脉40余条，矿脉受不同方向的构造控制明显，依据不同方向的构造特征厘定出与金矿的富集关系，其中EW，NE向构造为成矿前期构造，NNE向构造为成矿期构造（即同成矿构造），NW向构造为成矿后期构造，而NNE向同成矿构造为金的富集提供了有利的构造条件。

Abstract:

There are more than 40 strips of gold lodes in Jiudian gold area. Gold veins are controlled by different structures in all directions. Based on structural characteritics in different directions, relation between structure and gold concentration are classified. Structure with the trend of EW and NE are early period of ore-forming, while the structure with the trend of NNE is late period of ore-forming. The structure with the trend of NNE provide suitalbe conditions for gold concentration.
