sársins

Sársins, also known as sarsins or sarsen stones, are large, flat stones found in the southern English counties of Hampshire, Berkshire, Oxfordshire, and Wiltshire. They are primarily composed of a fine-grained sandstone, often referred to as sarsen sandstone, which is a type of siliceous sandstone. Sarsen stones are typically dark grey in color and have a smooth, polished surface, which is a result of millions of years of erosion.

The origin of sarsen stones is a subject of ongoing debate among geologists. One theory suggests that they were formed from the erosion of older rocks in the area, while another proposes that they were transported from the south by glaciers during the Ice Age. Regardless of their origin, sarsen stones are a significant geological feature in the region, with many of them being used in the construction of ancient monuments, such as Stonehenge.

Sarsen stones are also found in other parts of the world, including France, Germany, and the United States. However, the sarsen stones found in England are particularly notable for their size and quality, with some specimens measuring up to 10 feet in diameter and weighing several tons. Despite their age and size, sarsen stones remain an important part of the English landscape, and their study continues to provide valuable insights into the region's geological history.
