A team of scientists conducted research into the origins of the iconic Stonehenge altar stone and were able to disprove the 100-year-old theory of its origin. Live Science reports this.
It is alleged that scientists decided to test the theory of the origin of the stone using new equipment. Recall that in 1923, geologist Herbert Henry Thomas published a study of the “blue stones” located in the inner circle of Stonehenge. He noted that they were all mined in West Wales, including the unusual blue-green stone. Scientists are sure that the geologist was mistaken.
The researchers compared the stone samples with rock samples from 58 quarries from south Wales to the west of England, but no matching sample could be found. Having discovered that the stone contained a lot of barium, the team decided to go to the north of England and Scotland, where they hoped to discover a deposit of altar stone.
It was previously revealed that the cooling on Earth over the past 15 million years is associated with the appearance of an island where New Guinea is located. Read more about this in material Public News Service.
