===Lizard Peninsula===
{{Main|Lizard complex}}

The [[Geology of Lizard, Cornwall|geology of the Lizard peninsula]] is unusual, in that it is mainland Britain's only example of an [[ophiolite]], a section of oceanic crust now found on land.{{efn|Britain's only other example of an ophiolite, the Shetland ophiolite, is older, and linked to the Grampian [[Orogeny]].}} Much of the peninsula consists of the dark green and red [[Precambrian]] [[serpentinite]], which forms spectacular cliffs, notably at [[Kynance Cove]], and carved and polished serpentine ornaments are sold in local gift shops. This [[ultramafic rock]] also forms a very infertile soil which covers the flat and marshy heaths of the interior of the peninsula. This is home to rare plants, such as the [[Erica vagans|Cornish Heath]], which has been adopted as the [[county flower]].<ref>{{cite web |url = http://www.cornwall.gov.uk/index.cfm?articleid=5430 |title=The Cornish Heath – County Flower |access-date=5 February 2016 |url-status=dead |archive-url = https://web.archive.org/web/20080930154036/http://www.cornwall.gov.uk/index.cfm?articleid=5430 |archive-date=30 September 2008 }}</ref>
