Laboratories

There are only a few archaeomagnetic laboratories within the UK and none of these can offer a dedicated commercial dating service. It is therefore important to contact them as early as possible to discuss the possibility of visiting the site and the availability of staff to carry out the work.

The Archaeomagnetic Research Group (University of Bradford) offers commercial services for archaeomagnetic directional dating. The disc and tube sampling methods are used with orientation using sun or magnetic compass. The commercial service includes site visits, recording of the feature, sample collection, measurement, a.f. demagnetisation and report writing. We have particular expertise in integrating archaeomagnetic data with other dating methods within complex archaeological stratigraphies. We also manage the 'Magnetic Moments in the Past' database of archaeomagnetic measurements incorporating 765 measurements from 1962 to the present day.

GeoQuest Associates provide a directional magnetic dating service for samples obtained from sites in the British Isles. Sampling is carried out using the minimally destructive button method, with orientation via gyro, sun or magnetic compass. GeoQuest works in conjunction with Museum of London Archaeology in carrying out site visits, context assessment and sampling, with subsequent laboratory processing and analysis in our laboratory on the Isle of Man.

The Centre for Environmental Magnetism and Palaeomagnetism provide high resolution and quality archaeomagnetic dating, with specialism in multi-feature sites only. We specialize in dealing with features that are difficult to sample with conventional methods. We can also provide magnetic material characterization for calibrating and modelling large-scale gradiometer 'geophys' surveys.

The Liverpool Geomagnetism laboratory offers specialist work in:

  • Archaeointensity determination of unoriented material (pottery sherds, bricks, tiles etc) and oriented material ¿ conventional and / or microwave. The microwave method requires only small 5mm diameter by 3 mm length cores of material.
  • Thermal and AF demagnetisation for determination of declination and inclination
  • Dating using directions and or intensity using SV curves for the UK (Lodge & Holme 2009; Zananiri et al 2006)
  • On site sampling
  • Magnetic and electrical site surveying
  • Magnetic mineralogy characterisation using a Variable Field Translation Balance and susceptibility meters eg to investigate evidence for burning.
  • Authenticity testing
