By Sophie Tanno For Mailonline. A team of archaeologists have discovered a major new prehistoric monument just a short distance away from Stonehenge. Fieldwork and analysis have revealed evidence of 20 or more massive prehistoric shafts - more than 10 metres in diameter and five metres deep - forming a circle more than two kilometres in diameter around the Durrington Walls henge. Coring of the shafts suggest the features are Neolithic and excavated more than 4, years ago - around the time Durrington Walls was built. It is thought the shafts served as a boundary to a sacred area or precinct associated with the henge. Professor Vince Gaffney, of the University of Bradford, said: 'The area around Stonehenge is amongst the most studied archaeological landscapes on earth. Dr Richard Bates, of the university's School of Earth and Environmental Sciences, said: 'Yet again, the use of a multidisciplinary effort with remote sensing and careful sampling is giving us an insight to the past that shows an even more complex society than we could ever imagine.

June 10, Topics Bosigranearthworksfield systemsPrehistory. A detailed survey carried out in established relative chronologies that identified six distinct types of field pattern attributable to periods from the 2nd millennium BC to the post-medieval period.
However, establishing accurate dates for their creation and development remained a challenge. There are few ancient field systems around the world that have been directly dated, as many of the existing approaches - which include dating artefacts recovered from earthworks, dating through associated archaeological features, and direct dating of ecofacts and sediments using radiocarbon or optically stimulated luminescence OSL methods - can be problematic.
In the early stage of prehistoric studies, dating of any event or site was obtained tentatively. A particular event or specimen is dated in relation to other event or some reference point. Mar 17, It is the only method that can be used to date rocks, pottery and minerals for dates that are approximately between to 10, years old. This method is based on the fact that when a material is heated or exposed to sunlight, electrons are released and .

Small trenches were cut in selected boundary banks to collect soil samples along the entire sediment stratigraphy, and a portable OSL reader used to measure the luminescence signals of the samples in the field.
