| 摘 要： | 盖塔(Geita)金矿是坦桑尼亚重要的绿岩带型金矿之一。文章阐述了矿床地质背景、矿床地质特征,以及矿床同位素年代特征,并对矿床成矿模式进行了对比。在此基础上认为盖塔金矿以块状黄铁矿和浸染状黄铁矿的矿化为主,成矿时代约为2644~2680Ma,属于太古宙热液型金矿床,具有明显的"层控"特征,后生成矿模式可能是盖特金矿的矿床成因。

| Abstract: | Geita gold deposit is one of the most important greenstone type gold deposits in Tanzania. This paper summarizes the geological background, geological characteristics and isotopic characteristics of the deposit. In addition discussion of the metallogenic model is made. Mineralization mainly composed of massive pyritic and disseminated pyritic mineralization and aged at 2 644-2 680 Ma. It is a Archean hydrothermal gold deposit with distinctive "stratabound" characteristics. The authors consider it a epigenetic gold deposit. |

| Keywords: | Geita gold deposit Skumaland greenstone belt Neoarchean Tanzania |
