Ramon-IV rock shelter, Ramon Makhtesh ‘Crater’, Negev, Israel – excavated by Professor Steven Rosen (Ben Gurion University): phosphate and organic matter analyses undertaken by UWLAS, combined with thin section analyses (Dr Richard Macphail, UCL), have been used to investigate the presence of Neolithic stabling layers within the rock shelter deposits (photo: Richard Macphail)

Soils analysis is undertaken by Dr John Crowther, who has over 25 years’ experience of work on archaeological soils and sediments, and specialises in soil chemistry (especially phosphate) and magnetic susceptibility.

Service provided

  • Advice on sampling and analytical programmes to ensure rigorous scientific investigation within the client’s budgetary constraints
  • Site visits to advise on soils/sediments and sampling
  • Wide range of laboratory analyses undertaken
  • Key anthropogenic indicators:
    • Phosphate
    • Magnetic susceptibility and fractional conversion
  • General soil/sediment characterisation:
    • Loss-on-ignition (organic matter)
    • pH
    • Carbonate content
    • Particle size
    • Other soil/sediment properties (details available on request)
  • Assessment of a representative subset of samples prior to committing to a major programme of analysis to evaluate the likely cost-effectiveness
  • No job too small or large – single property for an individual sample through to multi-property analyses of hundreds of samples
  • Prompt reporting: results and publication-standard report, including statistical analysis (where appropriate), normally presented within 4 working weeks of receipt of samples for batches of up to 50 samples
