Abstract In this contribution an overview of oceanic lithosphere, associated ore deposits (sulphides, Fe and Mn oxides, chromitites) and their final destination in ophiolitic rocks are presented. This is followed by a discussion on massive sulphide mineralisation formed at mid-ocean ridges (MOR) and/or supra-subduction zones (SSZ). The geological characteristics and the genesis of the Cu-rich massive sulphide deposits of Cyprus and of the Oman ophiolite are discussed based on an extensive review of the published literature. This is followed by a synopsis of the ophiolitic terranes and associated mineral system in the Urals. We also present an overview of the ophiolitic belts and sutures of the Tethyan orogens, focussing on the podiform chromite deposits that they typically host, with a special focus on the ophiolitic chromitites of Turkey. A final section deals with possible ophiolites of Proterozoic and Archaean ages and, where applicable, associated chromitites. In the concluding remarks a brief note is made of some specific ancient seafloor hydrothermal constructs that have been interpreted as black chimneys in volcanogenic massive sulphide (VMS) deposits now hosted in ophiolitic sequences.

大洋岩石圈和蛇绿岩:相关矿床的诞生、生活和最终安息地

摘要 在这篇文章中,概述了大洋岩石圈、伴生矿床(硫化物、Fe 和 Mn 氧化物、铬铁矿)及其在蛇绿岩中的最终目的地。随后讨论了在大洋中脊 (MOR) 和/或超俯冲带 (SSZ) 形成的块状硫化物矿化。塞浦路斯和阿曼蛇绿岩的地质特征和富铜块状硫化物矿床的地质特征和成因在对已发表文献的广泛审查的基础上进行了讨论。随后是乌拉尔蛇绿岩和相关矿物系统的概要。我们还概述了特提斯造山带的蛇绿岩带和缝合线,重点关注它们通常拥有的豆状铬铁矿矿床,特别关注土耳其的蛇绿岩铬铁矿。最后一部分涉及元古代和太古代可能的蛇绿岩,以及相关的铬铁矿(如适用)。在结束语中,简要说明了一些特定的古代海底热液构造,这些构造被解释为现在位于蛇绿岩层序中的火山成因块状硫化物 (VMS) 矿床中的黑色烟囱。
