“…More advanced analytical tools used to study the contents of individual fluid inclusions in situ include laser Raman analysis, proton microprobe analysis (e.g., Ryan et al, 1993), secondary ion mass spectrometry (e.g., Diamond et al, 1990), Fourier transform-infrared spectroscopy (e.g., Pironon and Barres, 1992), confocal scanning laser microscopy (e.g., Pironon et al, 1998), and laser micropyrolysis (e.g., Wilkinson et al, 1994;Anderson et al, 1995). These measurements allow collection of detailed qualitative and quantitative geochemical data, including metal and organic speciation, bond types, and isotope analysis.…”
