I analysed the four spectra using the Philips Graphics and Identify programme. Unfortunately I was not able to convert the screens into something that could be of value to you. I know it can be done, but I could not convert it into .jpg or .gif files that contain all the required information. SMRR-1 Restrictions: Mineral subset of JCPDS Database Phases Identified: 73-1727 Fluorapatite 86-2237 Quartz, low 12-0088 Ankerite 83-1764 Siderite Unknown Phase(s) SMRR-2 Restrictions: None No phases have been identified. I believe that the phase is not listed in the JCPDS database.
