| 中文摘要: |
| 青城子矿集区是辽东地区重要的 Pb-Zn-Au-Ag多金属矿集区，白云金矿床位于青城子矿集区内，是区内重要的大型金矿床。本文通过野外地质调研和显微镜下观察，总结出不同类型矿石以及矿物组合的空间分布规律，硅钾蚀变岩型矿石分布于矿区东部、中部和西部地区；石英脉型矿石分布于矿区中部和东部。矿区东部矿石中含较多的黄铁矿、石英、黄铜矿；西部矿石中含较多的黄铁矿、石英、钾长石。本文进一步提出白云金矿床成矿作用特征标志，包括围岩蚀变标志、地层标志、构造标志、岩浆岩标志、地球物理标志和地球化学标志，并建立了白云金矿床的成矿模型。 |

| Qingchengzi orefield is an important Pb-Zn-Au-Ag polymetallic orefield in the Liaodong penin.sula, and Baiyun gold deposit is located in the Qingchengzi ore concentration area, which is an important large-scale gold deposit in the area. This paper explores the spatial distribution pattern of different types of orebody andmineral combination, based on detailed field and microscopic observations. The silica-potassium altered rock type orebody develops in the eastern, central and western areas of the mining area. The quartz vein type ore develops inthe central and eastern part of the mine area. There are more pyrite, quartz and chalcopyrite in the orebody from theeastern of the mining area, and more pyrite, quartz and potassium feldspar in the orebody from the western of themining area. The metallogenic regularity of the Baiyun deposit is summarized, which includes surrounding rock al.teration, stratigraphic, structural, magmatic, geophysical and geochemical characteristics, and the metallogenicmodel of the Baiyun gold deposit is established. |
