  2. Lunar magma ocean - Wikipedia

    en.wikipedia.org/wiki/Lunar_magma_ocean

    The Lunar Magma Ocean (LMO) is the layer of molten rock that is theorized to have been present on the surface of the Moon. The LMO was likely present on the Moon from the time of the Moon's formation (about 4.5 or 4.4 billion years ago [1]) to tens or hundreds of millions of years after that time. The LMO was a thermodynamic consequence of the ...

  3. Magma ocean - Wikipedia

    en.wikipedia.org/wiki/Magma_ocean

    Magma oceans are integral parts of planetary formation as they facilitate the formation of a core through metal segregation [3] and an atmosphere and hydrosphere through degassing. [4] Evidence exists to support the existence of magma oceans on both the Earth and the Moon. [1][5] Magma oceans may survive for millions to tens of millions of ...

  4. Geology of the Moon - Wikipedia

    en.wikipedia.org/wiki/Geology_of_the_Moon

    Crystallization of this magma ocean would have given rise to a differentiated body with a compositionally distinct crust and mantle and accounts for the major suites of lunar rocks. As crystallization of the lunar magma ocean proceeded, minerals such as olivine and pyroxene would have precipitated and sank to form the lunar mantle.

    One of the best-known moon rocks, ferroan anorthosite is thought to be pieces of the original lunar crust that could have been formed by a magma ocean, according to the Lunar and Planetary Institute.

  6. Giant-impact hypothesis - Wikipedia

    en.wikipedia.org/wiki/Giant-impact_hypothesis

    This lunar origin hypothesis has some difficulties that have yet to be resolved. For example, the giant-impact hypothesis implies that a surface magma ocean would have formed following the impact. Yet there is no evidence that Earth ever had such a magma ocean and it is likely there exists material that has never been processed in a magma ocean ...

  7. Internal structure of the Moon - Wikipedia

    en.wikipedia.org/wiki/Internal_structure_of_the_Moon

    Thermal state of the Moon at age 100 Ma. [1] Having a mean density of 3,346.4 kg/m 3, [2] the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core. This structure is believed to have resulted from the fractional crystallization of a magma ocean shortly after its formation about 4.5 billion ...

  8. Lunar mare - Wikipedia

    en.wikipedia.org/wiki/Lunar_mare

    Lunar mare. The near side of the Moon, with major maria and craters labeled. The lunar maria (/ ˈmæri.ə / MARR-ee-ə; sg. mare / ˈmɑːreɪ, - i / MAR-ay, MAR-ee) [1] are large, dark, basaltic plains on Earth 's Moon, formed by lava flowing into ancient impact basins. They were dubbed maria (Latin for 'seas') by early astronomers who ...

  9. KREEP - Wikipedia

    en.wikipedia.org/wiki/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. Its most significant feature is somewhat enhanced concentration of a majority of so-called "incompatible" elements [1] (those that are ...
