Hf-W chronology of the accretion and early evolution of asteroids and terrestrial planets
- T. Kleine, M. Touboul, +6 authors A. N. Halliday
- Geology
- 1 September 2009
The 182 Hf– 182 W systematics of meteoritic and planetary samples provide firm constraints on the chronology of the accretion and earliest evolution of asteroids and terrestrial planets and lead to… Expand
EARLY CRUSTAL EVOLUTION OF MARS 1
- F. Nimmo
- Geology
- 31 May 2005
▪ Abstract The bulk of the ∼50-km-thick Martian crust formed at ∼4.5 Gyr B.P., perhaps from a magma ocean. This crust is probably a basaltic andesite or andesite and is enriched in incompatible and… Expand
The Crust of the Moon as Seen by GRAIL
- M. Wieczorek, G. Neumann, +13 authors M. Zuber
- Medicine
- Science
- 8 February 2013
The Holy GRAIL? The gravity field of a planet provides a view of its interior and thermal history by revealing areas of different density. GRAIL, a pair of satellites that act as a highly sensitive… Expand
Transient Water Vapor at Europa’s South Pole
Europa's Plumes Jupiter's moon Europa has a subsurface ocean and a relatively young icy surface. Roth et al. (p. 171, published online 12 December 2013; see the Perspective by Spencer) analyzed… Expand
Energetics of the Core
- F. Nimmo
- Chemistry
- 2015
This chapter reviews theoretical approaches to calculating the energy and entropy budgets of the Earth's core. The energy budget allows the growth of the inner core with time to be calculated; the… Expand
A Hadean to Paleoarchean geodynamo recorded by single zircon crystals
- J. Tarduno, R. D. Cottrell, W. Davis, F. Nimmo, R. Bono
- Geology, Medicine
- Science
- 31 July 2015
Unlocking Earth's ancient magnetic past The magnetic field protects Earth's surface from deadly cosmic radiation and provides clues about the planet's interior. Tarduno et al. found that some of the… Expand
Heterogeneous accretion, composition and core–mantle differentiation of the Earth
A model of core formation is presented that involves the Earth accreting heterogeneously through a series of impacts with smaller differentiated bodies. Each collision results in the impactor's… Expand
Estimates of Martian crustal thickness from viscous relaxation of topography
- F. Nimmo, D. Stevenson
- Geology
- 25 March 2001
Isostatically compensated crustal thickness variations and associated topographic contrasts at the surface of a planet result in lateral pressure gradients, which may cause the lower crust to flow… Expand
Influence of early plate tectonics on the thermal evolution and magnetic field of Mars
- F. Nimmo, D. Stevenson
- Geology
- 25 May 2000
Recent magnetic studies of Mars suggest that (1) it possessed a periodically reversing magnetic field for the first ∼500 Myr of its existence and (2) plate tectonics may have been operating during… Expand
HOW THE GEYSERS, TIDAL STRESSES, AND THERMAL EMISSION ACROSS THE SOUTH POLAR TERRAIN OF ENCELADUS ARE RELATED
- C. Porco, Daiana DiNino, F. Nimmo
- Physics
- 1 September 2014
We present the first comprehensive examination of the geysering, tidal stresses, and anomalous thermal emission across the south pole of Enceladus and discuss the implications for the moon's thermal… Expand
