In an article published in the journal, the researchers announced they had solved a centuries-long mystery surrounding the origin of most of the large stones that make up the outer Stonehenge ring. Scientific achievements on Wednesday.
Based on geochemical data, the researchers found that 50 of the 52 large stones, sarsen megaliths, originated from the West Woods in Wiltshire, England, about 15 miles from where the prehistoric monument stands.
Smaller stones near the center of the structure, called blue stones, were previously traced back to Wales, nearly 125 miles away.
The monument was built around 2500 AD. Pr. BC, and there are still questions about how the stones, some of which weigh up to 30 tons, were transported.
“How they were moved to the site is still the subject of speculation,” David Nash, a geomorphologist and chief researcher at the University of Brighton, told Reuters.
“Depending on the size of the stones, they had to be either pulled or moved on rolls to Stonehenge. We don’t know the exact route, but at least we have start and end points.”
The fragmented primary sample, which was previously thought to have been lost, was returned to the United Kingdom from the United States in 2018, allowing the researchers to perform the tests. The second core was in 2019. In Salisbury, England, and a third nucleus has not yet been established.
