| 中文摘要: |
| 新城—焦家成矿带是胶西北矿集区重要成矿带之一,南吕—欣木矿段位于新城—焦家成矿带的南段,矿床受构造控制。本文通过浅部矿体勘查工程控制程度研究,确定合理的工程间距；结合矿化裂隙统计,总结了矿化富集特征；通过地球化学构造叠加晕研究,矿体尾部前缘晕的增强叠加指示了深部盲矿体存在的可能性,地球物理梯度带的变化位置是矿化体有利的赋矿空间。研究表明矿化蚀变带的强度、类型与查明的构造规模、期次有关,矿体规模、矿石类型与矿化蚀变分带存在相关性。经钻探探明金金属量186163kg,取得了较好的成果,为该矿段与类似成矿条件的地区找矿勘查提供了找矿思路与方向。 |

| Xincheng-Jiaojia belt is an important metallogenic belt in the Northwestern Jiaodong gold ore cluster. Nanlv-Xinmu section is located in the south-extending of Xincheng-Jiaojia metallogenic belt,the deposit of which is controlled by the structure. This paper has reasonably determined the engineering interval depending on the research of controlling situation in shallow ore bodies.Combining the statistical analysis of mineralized fissure, the metallogenic regularity has been summarized. According to the research of structural superimposed halo, the frontal halo in the tail of the orebodies became strong,which indicated the possibility for the existence of the deep blind ore deposits. The change location of geophysical gradient zone provided the advantageous space to the mineralization. The results show that the strength of mineralization alteration zone is related with the structure scal and times, and there was the correlation between the orebody scale, the ore type and mineralization and alteration zone.Good result has been achieved in mineral exploration. It provides the clues and directions for further exploration in this ore section and other regions with similar metallogenic conditions. |
