In your TC/EA-MS analysis of bulk water in a mineral grain, e.g. garnet, how can you be sure that the water is not released from microscopic mineral inclusions within the garnet host crystal, rather than being bound within the garnet crystal structure itself. In other words, how can you be sure that garnet hosts up to 2000+ ppm H2O? How did you do FTIR analysis of non-transparent grains? Is this reflectance FTIR rather than transmission FTIR? How much Fe is in your garnets (almandine component)? Typically the Fe peak overlaps with the water peaks in FTIR...
