Scientists discover why Stonehenge is so tough | Digital Trends Spanish

Stonehenge has always aroused the fascination of scientists and researchers around the world. It is one of the most iconic monuments on the planet and now professionals have discovered what has made it so resistant.

A study conducted by the University of Brighton and published in the Plos One magazine, points out that the key to Stonehenge’s strength lies in the geochemical composition of its rocks.

According to the work, they are composed of 99.7 percent quartz crystals, a material that is very durable, as well as being resistant to erosion and weathering. It is practically indestructible.

The sample for analysis was taken from stone 58, one of many stones that have been tumbled. It was subjected to conservation work in the 1950s after the discovery of a crack running through the stone.

The team in charge discovered that the structure of the sarsen (sandstone blocks) of quartz grains the size of sand, firmly cemented together by a mosaic of quartz crystals, was what allowed the stone to be so impervious to crumbling or erosion. .

“Having access to the drilled core of stone 58 was the Holy Grail for our research,” said co-author David Nash, a professor at the University of Brighton, in a statement.

“It is extremely rare, as a scientist, to have the opportunity to work with samples of such national and international importance.”

In the sample, the scientists found a large number of small quartz grains, which were arranged in a very strong matrix, like a kind of mosaic of interlocking crystals.

This caught the attention of the researchers.

“I wonder if the builders of Stonehenge could have known anything about the properties of the stones, and they chose not only the closest and largest blocks, but also those that were most likely to stand the test of time.”

From this study, it was determined that the stones came from an area known as the West Woods, in Marlborough, about 25 kilometers from the monument.
