| 中文摘要: |
| 鸿沟山金银多金属矿区处于北东向汕头—惠来深断裂带与北西向饶平—大埔大断裂交汇部位,晚侏罗世大北山火山盆地南缘,区内出露地层主要有上三叠统至下侏罗统头木冲组、银瓶山组碎屑岩,北西向断裂为主要控矿容矿构造,矿化与花岗闪长斑岩关系密切。矿(化)体呈脉状、似脉状产出。文章对矿区的地质特征、地球化学特征、矿(化)体特征及围岩蚀变、成矿规律进行了阐述和分析,通过综合研究,初步推断矿床成因属热液充填交代为主的脉状矿床,并提出了找矿方向。 |
| 英文摘要: |
| Honggoushan gold silver polymetallic deposit is located in the northeast to the Shantou-Huilai deep fault zone and NW Raoping-Dapu fault intersection, the south edge of the late Jurassic Dabeishan volcanic basin.The strata exposed in the main three Triassic to lower Jurassic head wood red group, Yinpingshan group of clastic rocks. NW faults is the main ore controlling structure.Mineralization and granodiorite porphyry are closely related. The ore bodies are output as vein or vein like. In this paper, the geological and geochemical characteristics, mineralized and orebodies characteristics, wallrocks alteration and metallogenic law are described and analyzed.Through comprehensive study, it is concluded that the deposit is a ore vein deposit which was formed mainly by hydrothermal filling metasomatism, and put forward the prospecting direction. |
