About this mock
This mock test introduces the foundations of forensic geology and geoforensics, tracing the discipline from its earliest casework through Georg Popp's pioneering soil comparisons in 1904 to the modern toolkit described by Raymond Murray. Questions span the history of the field, the scope of geological evidence in legal contexts, the nature of soil and sediment as trace evidence, the Munsell Soil Colour Chart system, and the principles of particle size and texture analysis. Statutory context where relevant includes the Indian Evidence Act 1872 (now Bharatiya Sakshya Adhiniyam 2023) provisions on expert opinion, and international standards from ASTM and ISO governing analytical soil methods.
This test is designed for students and practitioners of forensic science, environmental geoscience, and crime scene investigation who are building their grounding in the physical properties of earth materials, the history of the discipline, and the protocols that govern sample collection and comparison. The material is relevant to MSc and BSc programmes in forensic science worldwide.
Topics covered:
- History and pioneers: Georg Popp, Arthur Conan Doyle, Hans Gross, Raymond Murray
- Scope of geological evidence: soil, minerals, rocks, pollen, diatoms, dust
- Soil as trace evidence: transfer, persistence, collection, and comparison protocols
- Locard's Exchange Principle applied to geological materials
- Munsell Soil Colour Chart: hue, value, chroma notation
- Particle size classes: clay, silt, sand, gravel definitions
- Sieve and hydrometer methods for particle size distribution
- Discriminating power of soil evidence in casework
This test covers the introductory and foundational content of the subject. Allow 30 minutes.
