| 中文摘要: |
| 金银山锂矿床是湖北省赤壁市发现的一处锂矿床，含矿岩性以碎裂岩、碎裂粉砂质板岩、碎裂泥质板岩及煌斑岩为主。本文在分析区域地质背景的前提下总结了成矿地质特征，认为南部幕阜山岩体为锂矿床的形成提供了部分物质来源，含矿热液在运移时萃取了部分冷家溪群地层中的Li元素，区域近东西向F9断裂为成矿的导矿和储矿构造。矿床中含锂矿物为锂绿泥石，主要为热液成因，指示区内锂矿床属构造蚀变岩型，为一新类型锂矿床。通过对区内控矿因素和找矿标志的确定，认为矿区两侧的万家岭矿区和黄地脑矿区具有相似的成矿地质背景和较好的找矿线索，可成为今后找矿的理想地段，有发现大型锂矿床的潜力。 |
| 英文摘要: |
| The Jinyinshan lithium deposit has been discovered in Chibi City， Hubei Province. The lithology of the ore-bearing rocks primarily consists of cataclasite， cataclastic silty slate， cataclastic argillaceous slate， and lamprophyre. Based on the regional geological background， this study provides a summary of the metallogenic-geological characteristics of the Jinyinshan lithium deposit. It suggests that the southern Mufushan pluton served as a source for some of the ore-forming materials. Furthermore， the ore-bearing hydrothermal fluid extracted Li from the Lengjiaxi Group during its migration through the regional near-EW-trending F9 fault. The lithium-bearing mineral found in the deposit is primarily cookeite， which is of predominantly hydrothermal origin. The Jinyinshan lithium deposit， hosted within structurally controlled and altered rocks， represents a new type of lithium deposit. Through comprehensive investigations of the factors controlling ore formation and prospecting indicators in the area， it is believed that the Wanjialing mining area and the Huangdinao mining area， located on either side of the Jinyinshan mining area， share similar metallogenic geological backgrounds and exhibit promising prospecting clues. These areas have the potential to yield large lithium deposits if adequate investment is made. |
