项目摘要

The ability to precisely and accurately measure the chemical and isotopic compositions of materials on very fine scales, down to only a few thousanths of a metre, is critical for understanding and evaluating the whole spectrum of Earth and environmental earth system processes, and hence finding ways to solve or manage the societal issues that arise from them. This ability - quantitative microanalysis - is central to modern Earth System Science.Processes that occur on Earth often dictate particular behaviours in elements and isotope ratios. Precise determinations of these sensitive elements that occur in very, to extremely, low abundances in minerals, glasses, organic remains and skeletal materials allow geoscientists to investigate the effects of processes on different timescales. Current applications include, for example, evaluating the conditions of mineral and ore deposit formation, reconstructing the evolution of past volcanic eruptions in order to constrain future hazard, determining fluctuations in seawater surface temperatures over time and their relationships with global climate change, and even monitoring of long-term climatic variations from cave deposits.Accurate and precise isotopic measurements of stable and radiogenic isotopes further enable geoscientists to measure ocean acidification associated with global climate change, quantify the amounts and types of sources for fluids involved in a large variety of important earth processes from the surface to the deepest mantle, and determine the ages of ancient and recent rocks and minerals formed at both low- and high-temperatures.This proposal is to provide continued UK science community support for a world-class laboratory that enables the UK to excel in the quantitative microanalysis of Earth materials, and explore fundamental questions that have consequences for the planet, the environment and its population: the Edinburgh Ion Microprobe Facility.

精确，准确地测量非常精细的材料的化学和同位素组成，只有几米的少量，对于理解和评估地球和环境地球系统过程的全部范围至关重要，因此可以找到解决或管理从中出现的社会问题的方法。这种能力 - 定量微分析 - 对现代地球系统科学的核心。地球上发生的过程通常决定元素和同位素比的特定行为。对这些敏感元素的精确确定，这些敏感元素在矿物质，玻璃，有机残留物和骨骼材料中非常低的丰度中，使地球科学家可以研究过程对不同时间尺度的影响。当前的应用包括，例如，评估矿物质和矿石矿床形成的状况，重建过去的火山喷发的演变，以限制未来的危害，确定海水表面温度随时间变化的波动，以及它们与全球气候变化的关系，甚至从洞穴中的长期气候变化。使地球科学家能够测量与全球气候变化相关的海洋酸化，量化从表面到最深地幔的各种重要地球过程中涉及的流体的数量和类型，并确定古代和近期岩石和矿物质的年龄，在低温和高等教育中形成的量子量。地球材料的微分析，并探索对地球，环境及其人口产生影响的基本问题：爱丁堡离子微探针设施。
