Geochemical implications of the formation of the Moon by a single giant impact

  author={Horton E Newsom and Stuart Ross Taylor},
The origin of the Moon by a single massive impact of a body slightly larger than Mars with the Earth can explain the angular momentum, orbital characteristics and unique nature of the Earth–Moon system. The density and chemical differences between the Earth and the Moon are accounted for by deriving the Moon from the mantle of the impactor. A cosmochemically plausible impactor can be formed in the region of the inner Solar System, lending support to the impact hypothesis. 
Origin of the moon and lunar core formation
A recent model of the origin of the Moon in a giant impact put forth by O'Neill [1991a and b] states that the bulk abundances of siderophile elements in the Moon would be provided by the impactorExpand
The origin of the moon and the early history of the earth—A chemical model. Part 1: The moon
Abstract The chemical implications of a “giant impact” model for the origin of the Moon are examined, both for the Moon and for the Earth. The Impactor is taken to be an approximately Mars-sizedExpand
Origin of the Moon
The Earth-Moon system is unusual in several respects. The Moon is roughly 1/4 the radius of the Earth - a larger satellite-to-planet size ratio than all known satellites other than Pluto's Charon.Expand
Earth-Moon System, Planetary Science, and Lessons Learned
The origin and evolution of the Moon is now well understood. Many bizarre theories were proposed to account for our satellite before these were swept away by the data from the Apollo missions. We nowExpand
Core Formation During Early Accretion of the Earth
New information includes: better knowledge of the physics of metal segregation, improved geochemical data on the abundance of siderophile and chalcophile elements in the silicate part of the earth, and experimentalData on the partitioning behavior of sidersophile andChalcophophile elements. Expand
N-Body Simulation of the Formation of the Earth-Moon System from a Single Giant Impact
The giant impact hypothesis is the dominant theory of how the Earth-Moon system was formed. Models have been created that can produce a disk of debris with the proper mass and composition to createExpand
Chemical composition of the Earth after the giant impact
The giant impact hypothesis for the origin of the Moon has been widely accepted. One of the most important features of this hypothesis is that the impactor's metallic core was incorporated in theExpand
Early accretional history of the Earth and the Moon-forming event
Abstract The accretion of the Earth is considered in the broader perspective of the formation of the solar system. Formation of planets from dust, or from a giant gaseous protoplanet predict uniformExpand
Comparative Planetary Evolution
This chapter focuses on the Earth as a member of the solar system by comparing it to other planets. In its early stages of growth, the Earth probably had a magma ocean sustained by the heat sourcesExpand
Early Differentiation of the Earth and the Problem of Mantle Siderophile Elements: A New Approach
The long-standing problem of the excess abundances of siderophile elements in the mantle can be resolved by considering an equilibrium core-mantle differentiation in the earth at 3000 to 3500 kelvin, which results in mantle sidersophile element abundances that closely match the observed values.

Terrestrial origin of the Moon
Abundance patterns of siderophile elements in the Earth's mantle have been determined by complex processes connected with internal segregation of a metallic core amounting to 32% of the Earth's mass.Expand
Origin of the moon
The similarities in siderophile abundances strongly suggest that the Moon was derived from the Earth's mantle after the Earth's core had formed. The energy required to remove material from theExpand
Planetary science: A lunar perspective
An interpretative synthesis of current knowledge on the moon and the terrestrial planets is presented, emphasizing the impact of recent lunar research (using Apollo data and samples) on theories ofExpand
The unique lunar composition and its bearing on the origin of the Moon
The noble gas abundance patterns of Earth, Venus and Mars suggest that accretion of the terrestrial planets took place after the loss of H and He from the inner solar nebula. Since most meteoritesExpand
Siderophile elements in planetary mantles and the origin of the Moon
The origin of the moon is examined in the context of theories of planetary accretion and of siderophile element abundances inferred for the upper mantles of the earth, moon, and shergottite parentExpand
Models of the Earth's Core
Combined inferences from seismology, high-pressure experiment and theory, geomagnetism, fluid dynamics, and current views of terrestrial planetary evolution lead to models of the earth's core withExpand
Lunar composition: A geophysical and petrological synthesis
Lunar compositional constraints are derived on the basis of geophysical data (in particular, the lunar seismic model as revised by Nakamura) and petrological arguments. Only in the case of extremeExpand
Dissolution of the primordial rare gases into the molten Earth's material
Abstract We have shown in a previous paper that, if the primordial solar nebula existed when the Earth was formed, the Earth was once surrounded by a dense and massive primordial atmosphere, whoseExpand
Origin of the Moon-The Collision Hypothesis
In 1871, during his presidential address to the British Association in Edinburgh, Sir William Thompson (later Lord Kelvin) discussed the impact of two Earth-like bodies, asserting that "when twoExpand

Abstract We have recently measured the concentrations of W and Mo in a large number of terrestrial samples using a new neutron activation analysis method and from these data we have estimated theExpand
