Field emission electron microprobe

场发射电子探针是一种用于固体材料的空间分辨化学(元素)微观和纳米分析的仪器。这种分析设备用于矿物学、岩石学、地球化学和其他地质、化学或材料科学，以确定天然样品、实验或合成产品中的组成特征及其空间变化。矿物的组成提供了有关地质作用的物理化学条件的基本信息，并奠定了地质固体物质结构-性质关系的基础。我们提出了一个综合研究计划，将实验岩石学研究、面向现场的分析研究和热力学/动力学模拟相结合，并考虑矿物中的化学变化。我们的实验研究集中在平衡或动力学过程中的矿物稳定性、溶解度和元素分配，如岩浆系统中的晶体成核和生长。我们以野外为导向的研究使用矿物平衡来重建岩浆-热液转变和质量传输的复杂过程，重建热液流体，重点是控制热液系统中经济的金属丰度。这些方法产生了新的热力学或动力学数据，作为各种空间和时间尺度上的地质过程解释或预测模型的基础。

Field emission electron microprobe is an instrument for spatially-resolved chemical (elemental) micro- and nanoanalysis of solid materials. This analytical device is used in mineralogy, petrology, geochemistry and other geological, chemical disciplines or materials science to determine the compositional characteristics and their spatial variations in natural samples, experimental or synthetic products. The composition of minerals provides primary information on physico-chemical conditions of geological processes and underlies structure-property relations of geological solid matter. We propose an integrative research program, which combines experimental petrology research, field-oriented analytical studies and thermodynamic/kinetic modeling, and incorporating chemical variations in minerals. Our experimental studies concentrate on mineral stabilities, solubilities and element partitioning during equilibrium or kinetic processes such as crystal nucleation and growth in magmatic systems. Our field-oriented research uses mineral equilibria to reconstruct complex processes of magmatic-hydrothermal transitions and mass transport, reconstruction of hydrothermal fluid focusing as control of economic metal enrichments in hydrothermal systems. These approaches result in new thermodynamic or kinetic data, which serve as basis of interpretive or predictive models of geological processes at various spatial and temporal scales.
