Development of reliable proxies to distinguish significantly mineralized sedimentary basins, enhancing the likely discovery of new sediment-hosted cop

热液矿床是世界金属的主要来源。它们形成于流体流动状态，从地壳中的源岩或岩浆中提取金属，将它们作为溶液中的络合物运输，并将它们沉淀在有限的岩石体积中。沉积盆地是这种过程产生巨大矿床的环境之一，例如中非的铜钴矿床，每年分别产生15%和75%的这些关键技术金属。然而，这种独特的盆地显然是罕见的，虽然许多潜在的类似物是已知的。鉴于理论、实验和分析地球化学的最新发展，本博士项目的目标是：（i）可靠的地球化学代用指标，用于区分存款规模和矿石附近地区的“肥沃”沉积盆地;和（ii）使用这些数据来测试和完善当前关于盆地规模流体流动机制和沉积物容矿形成的假设，结合碳氢化合物部门的进展。

Hydrothermal ore deposits are the principal source of the world's metals. They form within fluid flow regimes which extract metals from source rocks or magmas in the Earth's crust, transport them as complexes in solution, and precipitate them in a limited rock volume. Sedimentary basins are one environment in which such processes produce giant deposits, such as the Cu-Co deposits of Central Africa which annually produces respectively 15% and 75% of these key, technology-enabling metals. However, such remarkably-endowed basins are apparently rare although many potential analogues are known. Given recent developments in theoretical, experimental and analytical geochemistry, the aim of this PhD project is to develop: (i) reliable geochemical proxies for distinguishing "fertile" sedimentary basins at the district to deposit scale, and proximity to ore; and (ii) use these data to test and refine current hypotheses for basin-scale fluid flow mechanisms and sediment-hosted ore formation, incorporating advances developed in the hydrocarbon sector.
