The source of stone used to build Stonehenge around 2500 BC has been debated for more than four centuries.

Recently, a new study showed that The huge boulders of the formation originated from a place only 15.5 miles apart.

The smaller”blue stone” near the center of the monument can be traced back to Wales, but the origin of the sarsen boulder that formed the main building of Stonehenge is still unknown.

Researchers have studied the chemical composition of these stones and learned that most of the sarsens boulders and sandstone boulders are from West Woods in Wiltshire, England.

Among them, the Sarsens boulder is 30 feet high and weighs 25 tons.

The research was published in”Science Advances” In the magazine.

Experts say that these stone statues are ancient versions of”Lego.”

The lead author of the study, David Nash, said in a statement:“Until recently, we didn’t know if there were any images that could produce (create) images. The possibility of stones like Sarsen.”

He said:”We use 21st century science to study and understand the past of the Neolithic Age, and answer a question of how many archaeologists argued. This is undoubtedly very exciting.”

Scientists used to analyze the composition of boulders by using portable X-ray fluorescence spectroscopy (PXRF).

The scientist explained in the statement:“Next, research The personnel performed inductively coupled plasma mass spectrometry (ICP-MS) detection and ICP atomic emission spectrometry (ICP-AES) on some samples previously drilled from a sarsen boulder and core samples from a series of sarsen boulders in southern England. Detection and comparison.”

The report explains:Of the 52 sarsen boulders on the monument, 50 have the same chemical properties and can be inferred to come from the same source area.

Then, the scientists compared the geochemical characteristics of the core extracted from Stone 58 of Stonehenge with the equivalent data of the Sarsens stone from southern England.

By comparing the test results, the scientists finally compared Stonehenge with West Woods in Wiltshire, 25 kilometers north, has been identified as the most likely source of most sarsens on the monument.

They said in a statement:“Why the builders of this megalithic monument chose this location is still a mystery. Although researchers believe that the size and quality of the West Woods stone and the builders can easily transport and use They, these reasons may be the deciding factors.”
