About this mock
This mock test probes advanced topics in forensic geology, covering the provenance analysis of gems, minerals, and cultural artefacts; the statistical frameworks used to compare soil and mineralogical samples; the national geochemical databases that underpin reference populations; the construction and communication of likelihood ratios; and the qualification, report-writing, and admissibility standards governing the forensic geologist as expert witness.
This test is designed for students, MSc and BSc learners, and practitioners of forensic Forensic Geology and Geoforensics who have already completed fieldwork, instrumental analysis, and geophysical survey, and are ready to engage with the interpretive, statistical, and legal dimensions of the discipline. It is also suitable for those preparing for postgraduate assessments, professional certification programmes, or expert-witness roles requiring a precise command of evidential standards.
Topics covered:
- Gem and mineral provenance: isotope systems, REE fingerprinting, and inclusion assemblages
- Cultural artefact attribution: lead isotopes and archaeometallurgical casework
- Classical statistics and likelihood ratios for soil sample comparison
- The reference population problem and its effect on LR evidential weight
- National and continental geochemical surveys: BGS G-BASE, FOREGS, NGU, and USGS NGS
- ENFSI verbal probability scale and its application to geological opinions
- Likelihood ratio calibration and Tippett plot validation
- Expert qualification, Daubert and CPR Part 35 duties, and continuing disclosure
Allow 30 minutes.
