Home chemical composition chemical compound crystal earth's crust inorganic compound mineralogy mineraloid rock silicate minerals silicon The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The crust is underlain by the mantle. The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust. The boundary between the crust and mantle is conventionally placed at the Mohorovi?i?

Discontinuity, a boundary defined by a contrast in seismic velocity. The crust occupies less than 1% of Earth's volume. The oceanic crust of the sheet is different from its continental crust. The oceanic crust is 5 km (3 mi) to 10 km (6 mi) thick and is composed primarily of basalt, diabase, and gabbro. The continental crust is typically from 30 km (20 mi) to 50 km (30 mi) thick and is mostly composed of slightly less dense rocks than those of the oceanic crust. Some of these less dense rocks, such as granite, are common in the continental crust but rare to absent in the oceanic crust. Partly by analogy to what is known about the Moon, Earth is considered to have differentiated from an aggregate of planetesimals into its core, mantle and crust within about 100 million years of the formation of the planet, 4.6 billion years ago.
The primordial crust was very thin and was probably recycled by much more vigorous plate tectonics and destroyed by significant asteroid impacts, which were much more common in the early stages of the solar system. Earth has probably always had some form of basaltic crust, but the age of the oldest oceanic crust today is only about 200 million years. In contrast, the 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.
A theoretical protoplanet named 'Theia' is thought to have collided with the forming Earth, and part of the material ejected into space by the collision accreted to form the Moon. As the Moon formed, the outer part of it is thought to have been molten, a “lunar magma ocean.” Plagioclase feldspar crystallized in large amounts from this magma ocean and floated toward the surface. The cumulate rocks form much of the crust. The upper part of the crust probably averages about 88% plagioclase (near the lower limit of 90% defined for anorthosite): the lower part of the crust may contain a higher percentage of ferromagnesian minerals such as the pyroxenes and olivine, but even that lower part probably averages about 78% plagioclase. The underlying mantle is denser and olivine-rich. The thickness of the crust ranges between about 20 and 120 km. Crust on the far side of the Moon averages about 12 km thicker than that on the near side.
Estimates of average thickness fall in the range from about 50 to 60 km. Most of this plagioclase-rich crust formed shortly after formation of the moon, between about 4.5 and 4.3 billion years ago. Perhaps 10% or less of the crust consists of igneous rock added after the formation of the initial plagioclase-rich material. The best-characterized and most voluminous of these later additions are the mare basalts formed between about 3.9 and 3.2 billion years ago. Minor volcanism continued after 3.2 billion years, perhaps as recently as 1 billion years ago. There is no evidence of plate tectonics.
Close * Indicates primary type Manufacturer: A company that makes stock products, which may be sold directly to customers and/or through distributors. Custom Manufacturer: A company that makes custom components or finished products according to a customer's specifications.

Turnkey Systems Integrator: A company that offers design, selection, sourcing and installation of equipment/machinery (manufactured by themselves or a 3rd party) for a custom solution conveyor, robotic, factory automation or other system. Trade Association: An organization, also known as an industry trade group, founded by businesses that operate in a specific industry that collaborates between its member companies. Close Quality Certifications are issued to suppliers by an accredited third party, verifying that the supplier complies with established quality standards. Quality standards are usually documents written by developing bodies such as the International Organization for Standardization (ISO) or trade organizations such as the Society of Automotive Engineers (SAE). Quality standards are used to compare an organization to what the authorities say are best practices for a quality management system.
Quality standards can either be written in terms general enough to be used across any industry or written with requirements for a specific industry. Industry specific quality standards may be written with the help of experts in that industry. Close Other Certifications/Registrations are general compliances, memberships, agreements or qualifications that do not relate to a quality management system or to a company's ownership status. These may include certifications that are issued to individuals or an entire company. Other Certifcations/Registrations may or may not require third party verification; in some cases, an organization may self-certify by issuing a certificate of compliance to a given standard or regulation. Safety and security programs often fall into this group.
Examples of other certifications/registrations include ITAR Registered and GSA Approved. • • • • • • • Custom Manufacturer* Custom manufacturer of connectors for electric power, electric wire & cable, computer & electronic equipment applications.
