中文摘要:
      该矿区铜矿化和锌铅矿化主要发生在二叠系和三叠系的灰岩、白云岩化灰岩、硅质和炭质页岩中,部分岩石具有较高的Au、Ag等元素的背景值。石英问长玢岩规模较大者,与铜矿化和其他矿化关系密切。主要矿石类型有夕卡岩型、硅质页岩型和角岩型3种。金主要以吸附形式存在胶状硫化矿物和草莓状黄铁矿中,在角岩中,金品位较高且见有较大颗粒的自然金。通过对3个中段的系统采样分析和计算机处理,得出该矿区金、银等有关元素的宏观分布模式。
英文摘要:
      Cu and Pb- Zn mineralization in the ore field occurred in Permian-Triassic limestone, dolomitized limestone, siliceous and anthrinoid shale. Some rocks possess relatively high An and Ag background values. Quartz diorite-porphyrite body is large in scale, and closely related with Cu mineralization. Absorbent An is dominant in colloform sulphide and in framboid pyrite.There are higher grade An in hornstone,in which large natural An particles have been found.After systematically sampling and analysing three sections,and computer processing,the macroscopic distributive pattern of An -Ag and related elements is presented.
