在荆山群建组剖面实地研究的基础上,补测了野头组的禄格庄剖面,考察了荆山区至平度区荆山群的相变规律,采用数学地质方法研究荆山群地层结构及生成环境,得知:荆山群无论在原岩建造、岩性组合、生成的古地理环境均不同于胶东岩群。荆山群形成于不稳定的冒地槽环境,相变剧烈,由荆山区至平度区厚度锐减,火山活动减弱。荆山群在总体上表现为三大周期,对应三个组,各组内部具有不同的沉积韵律和拟周期,野头组火山沉积和禄格庄组的砂泥质沉积是荆山群金的高丰度部位。野头组的火山建造形成于海底裂陷环境,金主要赋存在正常沉积与火山沉积的交变带中。产于进入火山活动和由火山活动转出的历史阶段,属火山喷气—溢流阶段的产物。
Based on the fieldwork of the section of Jianshan Qunjian Formation, the section of the Lugezhuang section of the Wild Tectonics Group was made up and the phase transformation law of Jingshan Group from Jingshan to Pingdu was investigated. The stratigraphic structure and formation environment of Jingshan Group were studied by mathematical geology method. Know: Jing mountain group, regardless of the original rock construction, lithology combination, generated paleogeographic environment are different from the Jiaodong rock group. Jing Mountain Group formed in the unstable impending trough environment, dramatic phase transition, from Jing Mountain area to Pingdu area plummeted thickness, volcanic activity weakened. The Jingshan Group is generally characterized by three major periods, corresponding to three groups with different depositional rhythms and quasi-periods within each group. The sand-mud deposition of the group of the Wild Group and the Lugezhuang Formation is the high-abundance site of the Jingshan Group gold . The formation of volcanoes in the group of the Wild Group formed in the seafloor rifting environment. Gold mainly existed in the alternating zone of normal sedimentation and volcanic sedimentation. Produced in the volcanic activity into and out of the volcanic activity of the historical period, volcano - overflow phase of the product.
