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) physical properties are unknown, as are the igneous mechanisms that formed them. This is because it is difficult to study: none of Earth's primary crust has survived to today. Earth's high rates of erosion and crustal recycling from plate tectonics has destroyed all rocks older than about 4 billion years, including whatever primary crust Earth once had. However, geologists can glean information about primary crust by studying it on other terrestrial planets. Mercury's highlands might represent primary crust, though this is debated. The anorthosite highlands of the Moon are primary crust, formed as plagioclase crystallized out of the Moon's initial
