项目摘要
A variety of elements, mostly metals, are important to support the technology that is a foundation to our modern society. This includes green technologies such as wind turbines and hybrid cars. It is important that we are able to efficiently find concentrations of these metals, which requires an understanding of how they are transported and concentrated in the crust of the Earth. My research is concerned with understanding the processes that lead to such concentrations of metals and the nature of the mineral deposits that contain them. Of particular interest are rare or critical elements such as lanthanum, neodymium, zirconium, tungsten and indium. Some of these are very important to green technologies; the average hybrid car contains 30 kg of rare earth elements. These elements are concentrated by a variety of processes that involve metal transport by magmas and fluids. It is the chemistry of these magmas and fluids that I study to gain insights into the concentration processes on a variety of scales. Natural systems such as these are chemically and physically complex on a microscopic scale, requiring us to develop and use techniques for the chemical characterization of earth materials on the micron scale. This includes using the abundances of various isotopes in minerals to trace the origins of the magmas and fluids from which they precipitated. In addition, the fluids that have carried the metals in many cases are trapped as microscopic "fluid inclusions" within minerals. Analysis of these allows us examine and characterize the actual fluids that were responsible for metal transport and concentration, even if this happened billions of years ago. These fluid inclusions are very small (typically <30 microns) and so we also develop and use micro-analytical techniques to chemically characterize them. The abundances of the commodities (metals and other elements) that are concentrated in ore deposits can vary significantly from one apparently similar environment to another, as can the size of otherwise similar deposits. This research is designed to understand the fundamental parameters and processes that influence the metal inventories of deposits and their size.
各种元素(主要是金属)对于支持为我们现代社会的基础的技术很重要。 这包括绿色技术,例如风力涡轮机和混合动力汽车。 重要的是,我们必须有效地找到这些金属的浓度,这需要了解它们如何运输和集中在地球的外壳中。 我的研究涉及了解导致金属浓度的过程以及包含它们的矿藏的性质。特别有趣的是罕见或关键的元素,例如灯笼,北极虫,锆,钨和ins。 其中一些对于绿色技术非常重要。平均混合动力汽车含有30公斤的稀土元素。 这些元素是由涉及岩浆和流体的金属传输的各种过程集中的。 我研究的是这些岩浆和流体的化学性质,以了解各种尺度上的浓度过程。诸如此类的天然系统在微观尺度上是化学和物理上复杂的,要求我们开发和使用技术以在微米尺度上对地球材料的化学表征化。这包括使用矿物质中各种同位素的丰度来追踪它们沉淀的岩浆和流体的起源。 另外,在许多情况下,携带金属的流体被困在矿物质内的微观“流体夹杂物”中。 对这些分析的分析使我们可以检查并表征负责金属运输和浓度的实际流体,即使发生在数十亿年前。 这些流体夹杂物很小(通常<30微米),因此我们还开发和使用微分析技术来化学表征它们。 集中在矿石沉积物中的商品(金属和其他元素)的丰度与另一种相似的沉积物的大小一样,从一个明显相似的环境差异很大。 这项研究旨在了解影响沉积金属库存及其规模的基本参数和过程。
