| 摘 要： | 邓格庄金矿床位于胶东牟平－乳山金矿带的北段，含金石英脉受NNE向断裂控制。工业矿体由矿化石英脉的富金段组成。富金矿体在走向上一般分布于NNE向断裂的转折地段，倾向上分布于断裂产状由陡变缓的过渡部位。控矿构造经历了压剪性到张剪性的演化过程，主要成矿作用发生于断裂的张剪性活动阶段。深部地质地球化学研究表明，Ⅱ号矿体深部还有隐伏矿体存在。

| Abstract: | Denggezhuang gold deposit is located in north of Muping Rushan gold ore belt. The occurrence of gold bearing quartz vein was controlled by NNE trending faulted zones. The ore body is in the gold rich part of ore bearing quartz vein. The gold rich ore bodies occurrs in the winding part of NNE trending fractures on strike and transforming part from steeply dipping to gently dipping on dip direction. The ore controlling faults underwent a evolutional process from compressional shearing to tensional shearing and the main ore forming process took place in the stage of tensional shearing. Studies on the primary geochemical halo from the deep of Denggezhuang gold deposit shows that the vein No.II has characteristics of reversed axial zonality. The authors considered that there should be blind ore body under the ore body No.II. |
