University of Brighton academics are helping solve the mystery of where the ancient stones at Stonehenge originate.
Different theories have been debated by archaeologists and geologists for more than 100 years and now English Heritage, which manages the prehistoric site in Wiltshire, is hoping chemical analysis and comparisons by the Brighton scientists will unlock the puzzle.
The origins of the smaller ‘bluestones’ at the centre of the monument have been traced to Pembrokeshire in west Wales. This latest research focusses on the large sarsen stones that make up the main stone circle and inner sarsen horseshoe.
In 2018, the Brighton team analysed the chemistry of the sarsen uprights at the monument. This latest research involved chemical analysis of the sarsen lintel stones that sit across the top of these uprights. The non-invasive procedure used a portable spectrometer that can identify chemical concentrations of a range of elements.
Professor David Nash, the University of Brighton’s Professor of Physical Geography, said: “We have now analysed the chemistry of all the sarsen stones and will be comparing the data against the chemistry of areas of sarsens from across southern England. Read More
