Magma ocean, the Glossary

Index Magma ocean

Magma oceans are vast fields of surface magma that exist during periods of a planet's or some natural satellite's accretion when the celestial body is completely or partly molten.[1]

Accretion (astrophysics)

In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, into an accretion disk.

See Magma ocean and Accretion (astrophysics)

Aluminium-26

Aluminium-26 (26Al, Al-26) is a radioactive isotope of the chemical element aluminium, decaying by either positron emission or electron capture to stable magnesium-26.

See Magma ocean and Aluminium-26

Anorthite

Anorthite (an.

See Magma ocean and Anorthite

Anorthosite

Anorthosite is a phaneritic, intrusive igneous rock characterized by its composition: mostly plagioclase feldspar (90–100%), with a minimal mafic component (0–10%).

See Magma ocean and Anorthosite

Astronomical object

An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe.

See Magma ocean and Astronomical object

Chondrite

A chondrite is a stony (non-metallic) meteorite that has not been modified, by either melting or differentiation of the parent body. Magma ocean and chondrite are planetary geology.

See Magma ocean and Chondrite

Earth

Earth is the third planet from the Sun and the only astronomical object known to harbor life.

See Magma ocean and Earth

Earth's inner core

Earth's inner core is the innermost geologic layer of the planet Earth.

See Magma ocean and Earth's inner core

Earth's mantle

Earth's mantle is a layer of silicate rock between the crust and the outer core. Magma ocean and Earth's mantle are planetary geology.

See Magma ocean and Earth's mantle

Earth's outer core

Earth's outer core is a fluid layer about thick, composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle.

See Magma ocean and Earth's outer core

Europium anomaly

The europium anomaly is the phenomenon whereby the europium (Eu) concentration in a mineral is either enriched or depleted relative to some standard, commonly a chondrite or mid-ocean ridge basalt (MORB). Magma ocean and europium anomaly are Geochemistry.

Giant-impact hypothesis

The giant-impact hypothesis, sometimes called the Theia Impact, is an astrogeology hypothesis for the formation of the Moon first proposed in 1946 by Canadian geologist Reginald Daly.

See Magma ocean and Giant-impact hypothesis

Hadean

The Hadean is the first and oldest of the four known geologic eons of Earth's history, starting with the planet's formation about 4.6 billion years ago (estimated 4567.30 ± 0.16 million years ago set by the age of the oldest solid material in the Solar System found in some meteorites about 4.567 billion years old), and ended 4.031 billion years ago.

See Magma ocean and Hadean

Impact event

An impact event is a collision between astronomical objects causing measurable effects. Magma ocean and impact event are planetary science.

See Magma ocean and Impact event

Iron

Iron is a chemical element.

See Magma ocean and Iron

KREEP

KREEP, an acronym built from the letters K (the atomic symbol for potassium), REE (rare-earth elements) and P (for phosphorus), is a geochemical component of some lunar impact breccia and basaltic rocks. Magma ocean and KREEP are Geochemistry and geology of the Moon.

See Magma ocean and KREEP

Lava planet

A lava planet is a type of terrestrial planet, with a surface mostly or entirely covered by molten lava.

See Magma ocean and Lava planet

Magma

Magma is the molten or semi-molten natural material from which all igneous rocks are formed.

See Magma ocean and Magma

Melting

Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid.

See Magma ocean and Melting

Moon

The Moon is Earth's only natural satellite.

See Magma ocean and Moon

Moon rock

Moon rock or lunar rock is rock originating from Earth's Moon.

See Magma ocean and Moon rock

Natural satellite

A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite).

See Magma ocean and Natural satellite

Nickel

Nickel is a chemical element; it has symbol Ni and atomic number 28.

See Magma ocean and Nickel

Plagioclase

Plagioclase is a series of tectosilicate (framework silicate) minerals within the feldspar group.

See Magma ocean and Plagioclase

Planet

A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself. Magma ocean and planet are planetary science.

See Magma ocean and Planet

Planetary differentiation

In planetary science, planetary differentiation is the process by which the chemical elements of a planetary body accumulate in different areas of that body, due to their physical or chemical behavior (e.g. density and chemical affinities). Magma ocean and planetary differentiation are planetary science.

See Magma ocean and Planetary differentiation

Planetary surface

A planetary surface is where the solid or liquid material of certain types of astronomical objects contacts the atmosphere or outer space. Magma ocean and planetary surface are planetary geology.

See Magma ocean and Planetary surface

Planetesimal

Planetesimals are solid objects thought to exist in protoplanetary disks and debris disks.

See Magma ocean and Planetesimal

Radioactive decay

Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation.

See Magma ocean and Radioactive decay

Solar System

The Solar SystemCapitalization of the name varies. Magma ocean and Solar System are planetary science.
