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.

精确和准确地测量材料的化学和同位素组成的能力非常精细，只有千分之几米，对于理解和评估地球和环境地球系统过程的整个范围，从而找到解决或管理由此产生的社会问题的方法至关重要。这种能力-定量微观分析-是现代地球系统科学的核心。地球上发生的过程通常决定了元素和同位素比率的特定行为。这些敏感元素在矿物、玻璃、有机残留物和骨骼材料中的丰度非常低，甚至极低，精确测定这些元素使地球科学家能够研究不同时间尺度上的过程的影响。目前的应用包括，例如，评估矿物和矿石存款形成的条件，重建过去火山爆发的演变，以限制未来的危险，确定海水表面温度随时间的波动及其与全球气候变化的关系，甚至是长期监控稳定同位素和放射性同位素的精确同位素测量进一步使地球科学家能够测量与海洋酸化有关的全球气候变化，量化了从地表到地幔最深处的各种重要地球过程中所涉及的流体来源的数量和类型，并确定在低温和高温下形成的古代和现代岩石和矿物的年龄。这项提议是为了继续为世界提供英国科学界的支持-爱丁堡离子微探针实验室是一个一流的实验室，使英国能够在地球材料的定量微量分析方面出类拔萃，并探索对地球，环境和人口产生影响的基本问题：爱丁堡离子微探针设施。
