河南洛宁县月亮沟银多金属矿床地质特征及找矿意义
Geological Characteristics and Prospecting Significance of the Yuelianggou Silver Polymetallic Deposit in Luoning County,Henan Province
【摘要】 河南省洛宁县月亮沟银多金属矿床位于华熊台缘坳陷熊耳山隆起熊耳山北坡的Ag-Au-Cu-Pb-Zn多金属成矿带,矿体赋存于太古界太华群草沟组及石板沟组,矿体以脉状、透镜状为主,次为扁豆状、不规则似层状。通过对区域成矿背景、矿区地质特征、物化探特征及成矿地质条件等方面的研究,对该成矿区带找矿前景、找矿意义进行了简要阐述,由太华群及熊耳群组成的变质核杂岩体及其接触部位发育的拆离断层,奠定了区内基本的构造格架,对区内金属矿产具有明显的控制作用,太华群及熊耳群之间穹状接触部位,是找矿的有利地段,认为在该地区开展拆离断层-变质核杂岩构造研究工作,对寻找同类型矿床具有重要的指导意义。
【Abstract】 The Yuelianggou silver polymetallic deposit is located in the Ag-Au-Cu-Pb-Zn polymetallic ore belt,Xiongérshan Mountains,Hua-xiong platform margin depression.. The orebodies occur in the Archean Taihua group Caogou and Shibangou Formations,and display veined and lenticular textures, with few irregular bedded textures. This paper presents the studies of regional metallogenic background,geological,geophysical and geochemical characteristics and metallogenic geological conditions of this deposit,and its metallogenic prospecting and prospecting significance. The result shows that the Taihua and Xionger groups metamorphic core complex and detachment faults at the contact site comprise the basic structural framework in the region. These structures exert a key control on the metal deposits,and the dome contact site between the Taihua Group and Xionger group is favorable for ore searching. It is thus inferred that doing research work in the areas of the detachment fault-metamorphic core complex will provide guidance significance for searching for similar deposits.
