Climate exposure

This is about exposure to a nationwide pressure this habitat type carries — not a verdict on this site's own management.

Coastal

Coastal habitats are exposed to sea-level rise and storm erosion. Where hard sea defences sit behind them, there's nowhere landward to retreat to — a squeeze that keeps compressing the habitat no matter how well it's managed.

Geology & landscape

Rock Type: Gabbro

Landscape processes: Coastal, Volcanic / Igneous

Description

Coverack Cove and Dolor Point SSSI Description The site is within the Cornwall Area of Outstanding Natural Beauty. The site was formerly notified as part of ‘Coverack Cliffs’ SSSI. The Lizard Complex consists of a large serpentinised peridotite body, largely enclosed by amphibolites, and cut by later gabbros, basic dykes and granitic veins. Recent interpretations consider the Complex to represent the tectonically juxtaposed remnants of a disrupted ophiolite complex. The Coverack beach section is one of the most famous geological localities in Cornwall, and provides an almost continuous section across a palaeo-Moho, or mantle-crust boundary. The oldest rocks are exposed in the southern part of the section and consist of the serpentinised peridotites and harzburgites of mantle character. The serpentinites are replaced northwards by a transition zone, consisting of complexly interdigitated peridotites, troctolites and gabbros, which in turn gives way to dominant gabbro. All of the rock-types are cut by later basaltic dykes. The field relations at Coverack provide critical evidence as to the relative age of the Lizard igneous rocks. The peridotites are the oldest, followed by the transition zone ultramafics, then the main Lizard gabbro with the basaltic dykes as the youngest intrusives present at the locality.
