| 中文摘要: |
| 河北涞源谢台金多金属矿床位于太行山北段，是近年来在阜平幔枝矿集区内新发现的矿床。矿区内圈定了 2条金矿体， Au达到了工业品位， Ag、Zn达到了伴生工业指标；金矿石自然类型为细脉浸染型金矿石，矿石结构为变余粒状、鳞片状变晶结构、角砾结构等。金矿脉均赋存于隐爆角砾岩内，从其矿体特征、赋矿岩性等分析，认为该矿床具隐爆角砾岩型矿床类型。该区成矿物质来源于壳幔混源的岩浆；依据大石峪岩体年龄 135～115 Ma，推断本矿床成矿时代属于燕山期。本文主要基于矿床地质特征、成矿年代、成矿物质来源，提出了对矿床成因方面的认识，以期为该区科学合理部署金矿地质勘查工作提供参考依据。 |
| 英文摘要: |
| The Xietai gold polymetallic deposit，located in the northern section of the Taihang Mountains in Laiyuan，Hebei Province，is a newly discovered gold polymetallic deposit of Fuping mantle branch tectonic ore setarea in recent years. Two gold ore bodies have been delineated within the mining area，with Au reaching industrial grade and Ag and Zn reaching the associated industrial indexes；The natural type of gold ore is fine vein-diffuse gold ore，and the structure of the ore includes granular，flaky crystalline，and angular gravel structure，etc. The gold veins are all occurred in hidden explosive breccia. Based on the characteristics of the ore body and the lithol.ogy of the ore bearing rock，it is believed that the deposit belongs to the hidden explosive breccia type. The ore-forming materials in this area come from magma. Based on the age of the Dashiyu pluton ranging from 135 to 115Ma，it is inferred that the mineralization period of this deposit belongs to the Yanshanian period. This article mainly proposes an understanding of the genesis of mineral deposits based on their geological characteristics， mineralization age，and source of ore-forming materials which provides reference bases for the scientific andrational deployment of gold mine geological exploration in the area. |
