What materials were used at Stonehenge?
The outcrop sedimentary rocks at Stonehenge are the Late Cretaceous, Santonian Age, calcium carbonates. The outcrop sedimentary rocks comprise the first construction material used by the Stonehenge builders. This material is approximately 85 million years old. These rocks are locally called the Seaford Chalk Formation (Stonehenge White Chalk). The oldest limestone sedimentary rocks at Stonehenge are the Mississippian Period (Early Carboniferous), Arundian Age, calcium carbonates. The Mississippian Period limestone sedimentary rocks comprise the first (1st) foreign construction material used by the Stonehenge builders. This material is approximately 340 million years old. These rocks are locally called the Birnbeck Limestone Formation (Stonehenge Whitestones). The volcanic rocks (oldest geologically) at Stonehenge are the Ordovician Period intrusive igneous diabases (dolerites), and extrusive igneous felsites (rhyolites) and tuffs (basic). The Ordovician Period igneous rocks comprise the second (2nd) foreign construction material used by the Stonehenge builders. This material is approximately 470 million years old. These rocks are locally called the Ordovician Volcanics (Stonehenge Bluestones). The oldest sandstone sedimentary rocks at Stonehenge are the Silurian and Devonian Period micaceous sandstones. The Silurian and Devonian Period sedimentary sandstone rocks comprise the third (3rd) foreign construction material used by the Stonehenge builders. This material is approximately 417 million years old. These rocks are locally called the Old Red Sandstone Formation (Stonehenge Coshestons). The youngest sandstone sedimentary rocks at Stonehenge are the Oligocene and Miocene Period silicates. The Oligocene and Miocene Period sandstone sedimentary rocks comprise the fourth (4th) foreign construction material used by the Stonehenge builders. This material is approximately 24 million years old. These rocks are locally called the Reading Formation (Stonehenge Sarsens). http://www.bgs.ac.uk

How long has the Stonehenge been standing for?
The oldest parts of Stonehenge are probably the rocks which form the circle, or the air that surrounds it. The rocks would be millions of years old. The air would be even older, but since its composition changed over the lifetime of our planet, this date is less certain. The stone circle in its present form is thought to be approximately 5000 years old, although the site is said to have been used even earlier.

Why are the large stones at Stonehenge called sarsen?
The large stones at Stonehenge are called sarsens because the term refers to a specific type of sandstone that is found in the region. These stones are notably large and were used in the construction of the monument due to their durability and strength. The word "sarsen" is believed to have originated from the Old French term "sarsin," which was linked to the word for "Sarsens," a group of people who once inhabited the area. Sarsens are prominent in the structure of Stonehenge, contributing to its iconic status and historical significance.
