It is a coarse-grained rock consisting of 40 to 90% olivine along with significant orthopyroxene and lesser amounts of calcic chromium-rich clinopyroxene.

Departments Of France
In the administrative divisions of France, the department (, ) is one of the three levels of government under the national level ("territorial collectivity, territorial collectivities"), between the Regions of France, administrative regions and the Communes of France, communes. There are a total of 101 departments, consisting of ninety-six departments in metropolitan France, and five Overseas department and region, overseas departments, which are also classified as overseas regions. Departments are further subdivided into 333 Arrondissements of France, arrondissements and 2,054 Cantons of France, cantons (as of 2023). These last two levels of government have no political autonomy, instead serving as the administrative basis for the local organisation of police, fire departments, and, in certain cases, elections. Each department is administered by an elected body called a departmental council (France), departmental council ( , ). From 1800 to April 2015, these were called gene ...

Lherzolite Lers
Lherzolite is a type of ultramafic igneous rock. It is a coarse-grained rock consisting of 40 to 90% olivine along with significant orthopyroxene and lesser amounts of calcic chromium-rich clinopyroxene. Minor minerals include chromium and aluminium spinels and garnets. Plagioclase can occur in lherzolites and other peridotites that crystallize at relatively shallow depths (20 – 30 km). At greater depth plagioclase is unstable and is replaced by spinel. At approximately 90 km depth, pyrope garnet becomes the stable aluminous phase. Garnet lherzolite is a major constituent of the Earth's upper mantle (extending to ~300 km depth). Lherzolite is known from the lower ultramafic part of ophiolite complexes (although harzburgite is more common in this setting), from alpine-type peridotite massifs, from fracture zones adjacent to mid-oceanic ridges, and as xenoliths in kimberlite pipes and alkali basalts. Partial melting of spinel lherzolite is one of the primary sourc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
