Geology of the Isle of Wight

The geology of the Isle of Wight is dominated by sedimentary rocks of Cretaceous and Paleogene age. This sequence was affected by the late stages of the Alpine Orogeny, forming the Isle of Wight monocline, the cause of the steeply-dipping outcrops of the Chalk Group and overlying Paleogene strata seen at The Needles, Alum Bay and Whitecliff Bay.
==Pre-Cretaceous==
Rocks of Devonian, Triassic and Jurassic age are known to be present in the subsurface of the island from boreholes and interpreted seismic reflection profiles. Up to 389 m of presumed Devonian sedimentary rocks been proved by six boreholes drilled on the island, consisting of claystone, siltstone, sandstone and quartzite, similar in type to other dated Devonian sequences. A nearly full Triassic succession has been drilled, reaching a maximum thickness of 450 m. Sandstones of the Sherwood Sandstone Group are overlain by claystones and siltstones of the Mercia Mudstone Group and limestones of the Penarth Group. A complete Jurassic succession is shown by the boreholes at Arreton, reaching over 1400 m in thickness, comprising mainly mudstones of the Lias Group, oolitic limestones of the Inferior and Great Oolite Group, claystones of the Kellaways and Oxford Clay Formations, bioclastic limestones of the Corallian Group, organic-rich mudstones of the Kimmeridge Clay Formation, limestones of the Portland Group and the lower part of the Purbeck Group. The entire sequence presents sedimentation in a shallow water environment.
