About this mock
This mock test covers the core laboratory techniques used by forensic geologists to characterise soil and mineral evidence, spanning heavy-liquid density separation, polarised light microscopy, X-ray fluorescence elemental mapping, inductively coupled plasma spectrometry, and powder X-ray diffraction with clay fraction analysis. Questions probe method selection, instrument parameters, data interpretation, and the comparative reasoning that underpins forensic soil evidence in legal and investigative settings.
This set is designed for students, practitioners, and researchers in forensic geology and geoforensics who need to apply laboratory methods to casework scenarios, choose between near-neighbour analytical techniques based on sensitivity or selectivity, and interpret mineralogical and geochemical data for evidential purposes. It suits postgraduate coursework in forensic geology, mineral identification laboratory practicals, and continuing professional development in geoforensics and trace evidence analysis.
Topics covered:
- Density-gradient separation and heavy-mineral suites using SPT and bromoform
- Polarised light microscopy, pleochroism, birefringence, and the Becke line test
- X-ray fluorescence principle, Moseley Law, matrix effects, and pXRF limits
- ICP-MS sensitivity, polyatomic interferences, and isotope dilution calibration
- ICP-OES echelle spectrometer and spectral line overlap resolution
- Powder XRD and Bragg Law applied to crystalline mineral identification
- Clay mineralogy: kaolinite, illite, smectite, chlorite, and diagnostic treatments
- Evidential language and comparative conclusion frameworks in geoforensics
Allow 30 minutes.
