Thickness of the Martian crust: Improved constraints from geoid-to-topography ratios (2004, background): “While such a scenario could plausibly lead to a core dynamo and explain the ancient crustal magnetic anomalies of this planet [Nimmo and Stevenson, 2000], plate tectonics would also efficiently cool the mantle and give rise to a thinner than observed crust [Breuer and Spohn, 2003].”
Constraints on the composition and petrogenesis of the Martian crust (2003, background): “Thermal models suggest that the stagnant lid model operating during the entire Martian evolution can more readily explain the volume and timing of crust formation than can a model of early plate tectonics followed by a stagnant lid [Hauck and Phillips, 2002; Breuer and Spohn, 2003].”
A spherical harmonic model of the lithospheric magnetic field of Mars (2014, background): “It is still under debate whether plate tectonics existed on early Mars [Sleep, 1994; Connerney et al., 1999; Harrison, 2002; Breuer and Spohn, 2003; Connerney et al., 2005], and the study of apparent polar wander and magnetization directions may help to answer this question.”
Thermal evolution of the Martian core: Implications for an early dynamo (2004, background): “Further, Breuer and Spohn (2003) find the present-day crustal thickness and the inference of a monotonically declining crustal production rate to be easier to reconcile with a stagnant lid regime operating throughout the planet’s history.”
The MAVEN Magnetic Field Investigation (2015, background): “Alternatively, an early dynamo can be driven by thermal convection, with or without plate 111 tectonics, for the first 0.5 – 1 Gyr [Breuer and Spohn, 2003; Schubert and Spohn, 1990; Stevenson et al., 112 1983; Connerney et al., 2004], persisting as long as the core heat flow remains above a critical”
EARLY CRUSTAL EVOLUTION OF MARS 1 (2005, background): “Although plate tectonics may reduce melting early on, it makes later melt generation, as suggested by observations, more difficult to achieve (Breuer & Spohn 2003).”
Geodesy constraints on the interior structure and composition of Mars (2011, background): “Compared to other published temperature profiles, our cold end-member is very similar to the mantle temperature profile proposed by Sohl and Spohn (1997) for their model B, whereas our hot end-member is comparable to the temperature profiles suggested by Zharkov and Gudkova (2005) and Khan and Conno”
Very recent and wide‐spread basaltic volcanism on Mars (2011, background): “Indeed, thermal evolution models of Mars suggest that volcanism should have stopped at least some hundred million years ago [Hauck and Phillips, 2002; Breuer and Spohn, 2003 ].”
Revised CRISM spectral parameters and summary products based on the currently detected mineral diversity on Mars (2014, background): “…with the more readily accepted view that Mars is a single-plate planet, where a stagnant lid model [Schubert et al., 2001] best explains volcanic production rates [e.g., Breuer, 2003], although other workers have suggested incipient or abortive plate tectonics on early Mars [e.g., Yin, 2012].”
What makes a planet habitable? (2009, result): “This hypothesis is in agreement with the model of Breuer and Spohn (2003) which predicts thermal convection early in the Martian history, so that the dynamo action could occur for hundreds of Myr.”
