| 摘 要： | 内蒙古赤峰南部地区是中国北方一个非常重要的金属成矿区。宁城县杨树沟门银-铜-铅-锌多金属矿化区及周边晚古生代、晚中生代的岩浆侵入和岩浆期后热液活动强烈,NE向、近EW向断裂构造及受其控制的中酸性脉岩发育,围岩蚀变分布广泛,局部显示了较为明显的银、铜、铅、锌等多金属矿化,有1∶50 000及1∶10 000化探综合异常显示,1∶5000地物化综合剖面异常清晰,通过探槽工程揭露具明显的矿化显示,该区具有较好的成矿远景。

Characteristics of Yangshugoumen Ag-Cu-Pb-Zn polymetallic district prospecting potentiality in Ningcheng of Inner Mongolia |

| Abstract: | Southern Chifeng area of Inner Mongolia is a very important metallic mineralization area in the north of China.Late Paleozoic and late Mesozoic magmatic intrusion and post magmatic hydrothermal activi-ties are intense in Yangshugoumen Ag-Cu-Pb-Zn polymetallic mineralization area and it peripheral area.NE-trending and nearly EW-trending fracture structures and intermediate-acidic vein rocks which are controlled by the fracture structures are well developed.Wall rock alteration are widely distributed,and Ag-Cu-Pb-Zn polymetallic mineralization is obvious locally.Geochemical prospecting works at 1 ∶50,000 and 1 ∶10,000 scale indicate composite anomalies,and composite geophysical and geochemical prospecting section at 1∶5000 scale shows clear anomalies.Through exploratory trenching,obvious mineralization parts are revealed.It appears that the area has favorable metallogenic prospect. |
