If we stood at the crossroads in Wootton and walked through Wootton village up Sandy Lane to the top of Boars Hill we’d be walking through 164 million years of geology.
WOOTTON, LAMBOROUGH HILL & WHITECROSS
1:50 000 scale bedrock geology description: Stanford Formation – Limestone. Sedimentary Bedrock formed approximately 157 to 164 million years ago in the Jurassic Period. Local environment previously dominated by shallow carbonate seas.
Setting: shallow carbonate seas. These sedimentary rocks are shallow-marine in origin. They are biogenic and detrital, generally comprising carbonate material (coral, shell fragments), forming beds and locally reefs.
WOOTTON VILLAGE & IN TO LOWER SANDY LANE
1:50 000 scale bedrock geology description: Ampthill Clay Formation And Kimmeridge Clay Formation (undifferentiated) – Mudstone. Sedimentary Bedrock formed approximately 152 to 164 million years ago in the Jurassic Period. Local environment previously dominated by shallow seas.
Setting: shallow seas. These sedimentary rocks are shallow-marine in origin. They are detrital, ranging from coarse- to fine-grained (locally with some carbonate content) forming interbedded sequences.
MID SANDY LANE
1:50 000 scale bedrock geology description: Lower Greensand Group – Sandstone. Sedimentary Bedrock formed approximately 101 to 126 million years ago in the Cretaceous Period. Local environment previously dominated by shallow seas.
Setting: shallow seas. These sedimentary rocks are shallow-marine in origin. They are detrital, ranging from coarse- to fine-grained (locally with some carbonate content) forming interbedded sequences.
TOP OF SANDY LANE
SOLID: 1:50 000 scale bedrock geology description: Lower Greensand Group – Sandstone. Sedimentary Bedrock formed approximately 101 to 126 million years ago in the Cretaceous Period. Local environment previously dominated by shallow seas.
Setting: shallow seas. These sedimentary rocks are shallow-marine in origin. They are detrital, ranging from coarse- to fine-grained (locally with some carbonate content) forming interbedded sequences.
SUPERFICIAL: 1:50 000 scale superficial deposits description: Northern Drift Formation – Sand And Gravel. Superficial Deposits formed up to 3 million years ago in the Quaternary Period. Local environment previously dominated by rivers (U).
Setting: rivers (U). These sedimentary deposits are fluvial in origin. They are detrital, ranging from coarse- to fine-grained and form beds and lenses of deposits reflecting the channels, floodplains and levees of a river or estuary (if in a coastal setting).
