In a long-lost fragment of Stonehenge, scientists have discovered rock particles that are almost 2 billion years old. The stone rod was removed during restoration work in 1958 and then preserved as a souvenir.
In 1958, Robert Phillips, a spokesman for the Van Moppes drilling company that helped restore Stonehenge, drilled a cylindrical core from a Stonehenge string. This is a unique artifact, since today it is not possible to take samples of Stonehenge stones: the monument is under protection.
Later, when Phillips emigrated to the United States, he took a sample with him. It was kept there as a souvenir. After the core was returned in 2018, the researchers were able to conduct a geochemical analysis of one of the pillars of Stonehenge.
Scientists have found that the towering standing stones of Stonehenge, or sarsens, are made from rocks that contain deposits ranging from 1.6 billion to 2 billion years old.
The analysis also showed that the core is composed of small grains of quartz that fit tightly to each other like a mosaic. By the way, this explains the megalith’s resistance to atmospheric influences over the past 5 thousand years. Scientists believe that this is why it became the ideal material for the construction of the monument.
