| 中文摘要: |
| 云南安宁碳酸盐黏土型锂矿位于上扬子古陆块康滇基底断隆带，通过普查工作，目前探获氧化锂资源量超36万 t。矿区内共发育8条矿体（V1-V8），呈层状似层状分布。区内下二叠统梁山组地层为赋矿地层（从下往上可分为8个岩性段），其与上覆地层中二叠统阳新组白云质灰岩、灰岩呈整合接触关系，与下伏地层上石炭统黄龙组灰岩呈平行不整合接触。矿床找矿标志主要有地层标志（梁山组）、构造标志（包括向斜标志和古不整合面接触标志）、岩性标志（黏土岩及铝土岩）、蚀变标志（黄铁矿化）和矿化标志（铝土矿）。该矿床成矿物质来自于下伏碳酸盐岩（泥盆系和石炭系地层），其成矿作用经历了陆表风化、原始沉积和埋藏保存3个阶段。 |
| 英文摘要: |
| The carbonate clay-type lithium deposit in Anning， Yunnan Province， is located in the Kangdian basement faulted uplift zone of the Upper Yangtze Block. Through the general survey， the current lithium oxide resource is over 360，000 tons. There are eight ore bodies （V1-V8） in the mining area， which are distributed in a layered and sub-layered manner. The Liangshan Formation of the Lower Permian is the ore-bearing stratum in the area （divided into eight lithologic sections from bottom to top），and it is in an integrated contact with the overlying stratum - the dolomitic limestone and limestone of the middle permian Yangxin Formation， and in a parallel unconformity contact with the underlying stratum - the Huanglong Formation of the Upper Carboniferous limestone. The main indicators for ore deposit exploration include stratigraphic indicators （Liangshan Formation）， structural indicators （including syncline indicators and paleo-unconformity contact indicators）， lithological indicators （claystone and bauxite）， alteration indicators （pyritization）， and mineralization indicators （bauxite）. The ore-forming materials of this deposit come from the underlying carbonate rocks （Devonian and Carboniferous strata）， and its ore-forming process has gone through three stages： surface weathering， primary sedimentation and burial preservation. |
