The Lizard atmosphere and extreme southerly location being uniquely suitable. This became the Goonhilly satellite earth station, now owned by Goonhilly Earth Station Ltd. Some important developments in television satellite transmission were made at Goonhilly station. A wind farm exists near to the Goonhilly station site. Known as the Lizard complex, the peninsula's geology is the best preserved example of an exposed ophiolite in the United Kingdom. An ophiolite is a suite of geological formations which represent a slice through a section of ocean crust (including the upper level of the mantle) thrust onto the continental crust. The Lizard formations comprise three
Crust (geology) bulk of the continental crust is much older. The oldest continental crustal rocks on Earth have ages in the range from about 3.7 to 4.28 billion years and have been found in the Narryer Gneiss Terrane in Western Australia, in the Acasta Gneiss in the Northwest Territories on the Canadian Shield, and on other cratonic regions such as those on the Fennoscandian Shield. Some zircon with age as great as 4.3 billion years has been found in the Narryer Gneiss Terrane. The average age of the current Earth's continental crust has been estimated to be about 2.0 billion years. Most
