摘要

岩浆的H2O含量对火山喷发的爆炸性、流变性能和结晶性有强烈的影响。因此,对岩浆液体中H2O的精确分析对于我们理解岩浆过程和喷发的动力学至关重要。拉曼光谱提供了一种方便、经济、高空间分辨率的技术,用于估算喷发过程中被淬灭成玻璃的岩浆的H2O含量。然而,从拉曼光谱计算H2O浓度涉及人工数据处理,因此结果对所使用的特定处理很敏感。SilicH2O是一个开源软件程序,通过提供交互式图形用户界面,统一和简化了这一过程。它可以用于:(a)处理硅酸盐玻璃的拉曼光谱,(b)通过插值和解混去除任何不需要的峰,(c)用参考物质建立H2O校准,(d)定量未知样品的H2O含量。

SilicH2O: a graphical user interface for processing silicate glass Raman spectra and quantifying H2O
H2O contents of magmas strongly impact the explosivity of volcanic eruptions, as well as their rheological properties and crystallisation behaviour. Accurate analyses of H2O in magmatic liquids are therefore vital for our understanding of the dynamics of magmatic processes and eruptions. Raman spectroscopy provides an accessible, affordable and high spatial resolution technique for estimating H2O contents of magmas that have been quenched to a glass during eruption. However, calculating H2O concentrations from Raman spectra involves manual data processing and results are therefore sensitive to the specific treatment used. SilicH2O is an open-source software program that uniformises and streamlines this process by providing an interactive graphical user-interface. It can be used to: (a) process Raman spectra of silicate glasses, (b) remove any unwanted peaks through interpolation and unmixing, (c) set up H2O calibrations with reference materials and (d) quantify H2O contents of unknown samples.
