摘　　要：沙特阿拉伯作为“一带一路”沿线重要节点国家,与我国在矿产资源开发领域具有深入合作。沙特阿拉伯境内有资料记载的金矿点(床)近1000个,开展过钻探勘查的有51个,都分布于阿拉伯地盾区,与新元古代克拉通的形成关系密切。通过搜集大量资料,本文重点研究描述了MAHD ADH DHAHAB金矿床和AL AMAR金矿床的成矿地质特征,并在此基础上对全国35个工作程度较高的地区(5个金矿床和30个远景勘查区)成矿特征进行了总结,认为绝大多数金矿化都是与粗粒侵入岩、岩床或岩墙、火山沉积岩中的石英脉以及火山沉积岩中的层状矿化相关的原生矿化,次生矿化主要发育在一些富含硫化物的氧化带及砂矿中,具有与苏丹、厄立特里亚相似的矿床产出特征,开发潜力巨大。Saudi Arabia,as an important country along the"one belt-one road",has a deep cooperation with China in the field of mineral resources development.There are nearly 1000gold occurrences recorded in Saudi Arabia,51ore spots of which have been carried out for the drilling exploration.These ore occurrences are distributed in the Arabian shield area and closely related to the formation of Neoproterozoic craton.Based on a large amount of data collected,this paper mainly studies and describes the metallogenic geological characteristics of MAHD ADH DHAHAB gold deposit and AL AMAR gold deposit.It has summarized of the metallogenic characteristics of 35 areas(5gold deposits and 30 selected prospective areas)with high working degree.It is considered that most of the gold mineralization is primary mineralization related to coarsegrained intrusive rocks,rock beds or dikes,quartz veins in volcanic sedimentary rocks and the bedded mineralization in volcanic sedimentary rocks.The secondary gold mineralization is mainly developed in some sulfide-rich oxidation zones and placer deposits,and the characteristics of deposit output is similar to that in Sudan and Eritrea.There is a great potential for gold deposit development in Saudi Arabia.
