what type of sediments are the white cliffs of dover made of
White Cliffs of Dover The White Cliffs of Dover are cliffs that form part of the English coastline facing the Strait of Dover and France. The cliffs are part of the North Downs formation. The cliff face, which reaches up to 350 feet (110Â m), owes its striking appearance to its composition of chalk accented by streaks of black flint. The cliffs stretch along the coastline for eight miles (13 km), spreading east and west from the town of Dover in Kent, and part of them were purchased by the National Trust in 2016.[1] They are part of the Dover to Kingsdown Cliffs Site of Special Scientific Interest[2] and Special Area of Conservation[3]
Sedimentary rock Clastic sedimentary rocks are composed of other rock fragments that were cemented by silicate minerals. Clastic rocks are composed largely of quartz, feldspar, rock (lithic) fragments, clay minerals, and mica; any type of mineral may be present, but they in general represent the minerals that exist locally.
