Archaeomagnetic dating

TAAL is currently involved in a major program of dating and sampling burnt archaeological features, lake sediments and volcanics in Australia to build the first, and world’s longest Archaeomagnetic Dating Reference Curve.

Read More Archaeomagnetic dating --dating archaeological and geological materials by comparing their magnetic data with known changes in the earth's magnetic field--has proved to be of increasing reliability in establishing behavioral and social referents of archaeological data.

Reference archaeomagnetic secular variation (SV) curves recently have been proposed for the Iberian Peninsula and may now be used for archaeomagnetic dating.More specifically I am looking at ” Developing Archaeomagnetic Dating for the Scottish Neolithic” (Ph D title).By sampling fired material from independently dated archaeological material we can begin to build a picture of the past geomagnetic field behaviour.(resource) Archaeomagnetic dating is based on the use of known secular variation in the three components of the Earth’s magnetic field (Horizontal, Vertical and Intensity) to date burnt features that contain the fossil direction of these components of the field.These three components are fossilised within burnt rocks (volcanics), sediments (fireplace), artefacts (pottery, FMR, bricks and heat retainers) as they cool within the Earth’s Magnetic Field.
