中文摘要:
      铜鱼梁铜矿床位于阿奇山—雅满苏铁(铜)成矿带东部,成矿地质条件优越。本文通过该矿区地质填图、磁法测量及岩屑地球化学测量等研究工作,确定其成矿地质特征及找矿标志,提出找矿方向。研究结果表明:铜鱼梁铜矿床赋存于下石炭统阿奇山组第二岩性段及闪长玢岩中。矿体呈稀疏浸染状和细脉状产出,主要发育粒状结构和块状构造。围岩蚀变以绿泥石化、绿帘石化和硅化为主。以Cu-As-Zn-Sb-Pb-Ag为元素组合的综合异常和弱磁异常分别指示矿体赋存地段的地球化学特征和地球物理特征。结合区域典型矿床研究表明,铜鱼梁铜矿是与火山-次火山热液活动相关的铜矿床,指出矿化带的深部及西南方向为下一步的找矿方向。
英文摘要:
      The Tongyuliang copper deposit is located in the eastern part of Aqishan-Yamansu iron (copper) metallogenic belt. There are excellent metallogenic geological conditions in this region. Through the research work of geological mapping, magnetic measurement and geochemical measurement of rock debris in this mining area. The prospecting direction is suggested along with a summary of the prospecting criteria and metallogenic geological features. The results show that the Tongyuliang copper deposit occurs in the second lithologic section of the Lower Carboniferous Aqishan Formation and diorite porphyrite. The ore bodies are sparsely disseminated and veinlet shaped, with granular structure and block structure characteristics. The surrounding rock alteration is mainly composed of chloritization, epidotization and silicification. The comprehensive anomaly with Cu-As-Zn-Sb-Pb-Ag as the element combination indicates the geochemical characteristics of the ore body occurrence area, as well as the weak magnetic anomaly indicates its geophysical characteristics. Combined with the study of typical deposits in the region, the Tongyuliang copper deposit is a copper deposit related to volcanic-subvolcanic hydrothermal activity.We also pointed out that the deep and southwest direction of the mineralized belt is the next prospecting direction.
