Mineral and Phase Identification

X-ray diffraction is used for qualitative mineral and crystalline phase identifications from powder samples. Semiquantitative content of rock forming minerals (quartz, muscovite, chlorite, plagioclase, K-feldspar, calcite, dolomite, magnesite, siderite, talc, kaolinite, gypsum, anhydrite, garnet, cyanite, hornblende, pyrite) can be obtained by individual calibration. Based on the identified and quantified mineral phases the equivalent quartz content (F_ÄQu) can be determined according to DGGT Recommendation No. 25.

Equipment:

• Diffractometer Panalytical XPert (Co-tube)
• Philips PW 1830 (Cu-tube)
• Panalytical Highscore Plus Software
