We're going to dig it! ---------------------. Stonehenge Building Materials: For those unfamiliar with the 5 basic rock types at Stonehenge; here is a list of them in chronological order of their first arrival. 85 MYA White Chalk - The outcrop sedimentary rock of Stonehenge is Late Cretaceous Period, Santonian Age, calcium carbonate. Late Cretaceous Period outcrop sedimentary rock is the in situ construction material used by the Stonehenge builders. This material is approximately 85 million years old. This stone is called Seaford Chalk Formation rock. White in color, this building material is from Stonehenge Ditch Mining area. 3100 BC Whitestone - The oldest limestone sedimentary rock of Stonehenge is Early Carboniferous (Mississippian) Period, Arundian Age, calcium carbonate.
Stone is the one of the major building materials. It is a versatile material and hence it can be used from the foundation to the parapet in a building and hence the scope comprises the study of use of different stones at these places.lthough slate is not strictly a building stone, it is used extensively for covering steps and the roofs of buildings, for wall linings, and for sanitary purposes. Slate is sometimes used to make light traffic macadam, but, although it packs well, it ultimately yields much mud and dust, which are objectionable.
