ANU X-ray Diffraction Laboratory


 Dr Ulrike Troitzsch


  • Qualitative analysis (eg. identification of minerals in rocks)
  • Quantitative analysis (eg. determination of mineral abundances and amorphous content in rocks)
  • Clay identification (Mg-saturation, glycolation, 350°C, 550°C)
  • Clay separation by settling method (Stoke's Law)
  • Sample preparation (eg. crushing, milling, micronizing)
  • Illite crystallinity determination (based on FWHM of 10 Å reflection)
  • Crystal structure refinement (Rietveld method)
  • Specializing in small sample sizes (0.001 mg)
  • Calcite/Aragonite quantification (corals, shells)
  • Training in usage of all instruments and software

Courses for users

  • Special workshop 'Introduction to X-ray diffraction' is highly recommended for Earth Science postgraduate students and staff:  (3 days, held on demand). Topics covered are X-ray diffraction principles, instrumentation and software, phase identification and quantification, Rietveld refinement. Practical sessions allow hands-on experience in the lab, and data analysis performed with programs Rietica, Siroquant and DiffracPlus Eva.
  • Special workshop 'Introduction to X-ray diffraction for Archaeologists' is highly recommended for archaeology postgraduate students and staff (half day, held on demand). Topics covered are basic X-ray diffraction principles, archaeological applications, instrumentation and software, phase identification and quantification.
  • Basic knowledge in Mineralogy is highly recommended for undergraduate students (eg. course EMSC 2017)
