Fertility of subduction and post subduction magmatism associated with porphyry- and epithermal-Cu-Au mineralisation in the Aegean using zircon geochro

英国已通过立法，到2050年实现温室气体净零排放。这将需要新的地质资源来支持非化石燃料运输和能源生产。斑岩铜矿是世界上铜的主要来源，铜是电动机和发电机的关键原材料。在某些地球动力学环境中，它们还因富含多种微量元素和矿物而引人注目，包括清洁能源生产中使用的“关键”元素，如Te、Pt、Pd、Bi和Sb。因此，在争取“净零”的努力中，将需要新的斑岩铜矿资源，因此，需要更好地了解导致其形成的关键过程和可发现的地点。（如锆石和磷灰石）和岩浆地球化学与高精度U-锆石的铅地质年代学是当前重要研究工作的重点，因为它们有可能区分肥沃和贫瘠的斑岩铜矿系统[例如1]。目的是对斑岩铜矿形成的岩浆作用和成岩作用有一个新的认识，并为斑岩铜矿的勘探提供新的工具。到目前为止，重点一直放在安第斯山脉上--一个俯冲的背景。然而，俯冲后岩浆活动是一种常见现象，越来越多地被认为是形成特殊斑岩-浅成热液型矿床的重要控制因素，如上所述，也是技术要素的重要来源。爱琴海是一个在过去33 Ma中具有复杂但相当好理解的地球动力学和岩浆历史的地区，主要是俯冲后风格，但也涉及活动，虽然缓慢，俯冲。它还具有与这种地球动力学和岩浆演化同时发展的发育良好的斑岩和低温热液型矿化，它们共同为在俯冲后环境中开发辅助矿物斑岩-铜肥力指标提供了一个强大的模板。

The UK has passed legislation to reach net zero greenhouse gas emissions by 2050. This will require new geological resources to underpin non fossil fuel transport and energy generation. Porphyry copper deposits are the world's major source of copper - a key raw material in electric motors and dynamos. They are also notable, in certain geodynamic environments, for their enrichment in a wide range of trace elements and minerals, including "critical" elements, such as Te, Pt, Pd, Bi and Sb, used in clean energy generation. Hence, in the drive for "net zero", there will be a requirement for new porphyry-copper resources and consequently a better understanding of the key processes that result in their formation and the locations where they can be found is required.Accessory minerals (e.g. zircon and apatite) and magma geochemistry coupled with high precision U-Pb geochronology on zircon are the focus of significant current research effort as they have the potential to distinguish fertile from barren porphyry copper systems [e.g. 1] with the aims of developing a new understanding of the magmatic and petrogenetic processes responsible for porphyry copper formation and to provide new tools for their exploration. To date, the emphasis has been on the Andes - a subduction setting. However, post-subduction magmatism is a common phenomenon and is increasingly recognised as an important control on the formation of exceptional porphyry-epithermal style ore deposits and are, as noted above, an important source of technology elementsThe Aegean is a region that has a complex, but reasonably well understood geodynamic and magmatic history over the last 33 Ma, that is predominantly post-subduction in style but also involves active, albeit slow, subduction. It also has well-developed porphyry and epithermal style mineralisation developed coevally with this geodynamic and magmatic evolution, which together provide a robust template for developing accessory mineral porphyry-copper fertility indicators in a post-subduction setting.
