A chemical analysis of the Altar Stone at Stonehenge reveals it originates from Scotland, challenging previous beliefs that it came from Wales, and suggesting advanced prehistoric trade networks and societal organization.
A chemical analysis of the Altar Stone at Stonehenge reveals it originates from the Orcadian Basin in Scotland, challenging previous beliefs that it came from Wales. This discovery suggests advanced prehistoric trade networks and societal organization, including possible marine routes for transporting massive stones over long distances during the Neolithic era.
A new study challenges the 100-year-old theory about the origin of Stonehenge's Altar Stone. Previously believed to have come from the Preseli Hills in western Wales, researchers now suggest that the stone may have originated from a different location, possibly in northern England or Scotland. The study compared the geochemistry and mineralogy of the Altar Stone with various sandstone outcrops but failed to find a match. The stone's high barium content has led researchers to explore areas with known Neolithic monuments in northern England and Scotland. This research rewrites the archaeological significance of the Altar Stone in the history of Stonehenge.
A study led by researchers at Aberystwyth University has challenged a century-old theory about Stonehenge's Altar Stone, suggesting it may not have come from the same source as the other stones used in the monument's construction. Previous theories proposed that the Altar Stone originated from the Old Red Sandstone formation in west Wales, like the other bluestones. However, new analyses have revealed that the Altar Stone's composition and high barium content distinguish it from the basin and bluestone samples in the Anglo-Welsh Basin. This discovery raises doubts about the Altar Stone's origin and suggests the need to broaden the search geographically and stratigraphically.
