| 中文摘要: |
| 卡瓦依金矿床位于吉尔吉斯斯坦南天山构造带内，其矿床地质及地球化学特征的总结对区域上同类型矿床的找矿勘查工作提供有益参考。卡瓦依金矿区矿体赋存于断裂构造蚀变带中，矿体主要呈透镜状、脉状和薄层状产出。矿石矿物主要为黄铁矿，次为黄铜矿，微量黝铜矿、磁黄铁矿和毒砂。围岩蚀变以硅化、绢云母化、碳酸盐化、绿泥石化和黄铁矿化为主。矿石主要发育碎裂结构、粒状结构和交代结构，具有条带状、浸染状构造。矿体赋存地段表现为 Au-As-Sb-Pb-Mo元素组合的综合异常。综合该矿床成矿地质特征，推测卡瓦依金矿成因属于构造蚀变岩型。 |
| 英文摘要: |
| The Kavai gold deposit is situated within the South Tianshan Tectonic Belt of Kyrgyzstan. A systematic summary of its geological and geochemical characteristics provides beneficial reference for the prospect.ing and exploration of similar deposits in the region. The ore bodies in Kawayi gold mine occur within the faultstructural alteration zone，and the ore bodies are mainly exhibiting lenticular，veined and thin-bedded. The ore minerals are mainly pyrite，followed by chalcopyrite，with minor tetrahedrite，pyrrhotite and arsenopyrite. Wall-rock alterations are characterized by silicification，sericitization，carbonation，chloritization and pyritization. Ore textures display cataclastic，granular，and metasomatic structures，with banded and disseminated fabric patterns. The ore-hosting intervals demonstrate comprehensive geochemical anomalies of Au-As-Sb-Pb-Mo element assemblages. Based on a comprehensive analysis of metallogenic features，it is speculated that the genesis of the Kawayi gold deposit belongs to the structural altered rock type. |
