Hadean geodynamics and the nature of early continental crust
2021, Precambrian ResearchCitation Excerpt :Though it might be possible to generate a magnetic field with a basal magma ocean (Ziegler and Stegman, 2013), the formation of a basal magma ocean itself is not guaranteed (§4.2). The presence of the geomagnetic field in the Hadean is still controversial (e.g., Weiss et al., 2016; Tarduno et al., 2020), but it would contribute to the habitability of surface environment by shielding high-energy cosmic rays from the young Sun (Grießmeier et al., 2005). The regime of Hadean geodynamics, as mentioned in Introduction, may be inferred from how the continental crust has grown, which could constrain the onset time of plate tectonics, and from how a magma ocean solidified, which would have prescribed the initial state of subsolidus mantle convection.
Cluster analysis on a sphere: Application to magnetizations from metasediments of the Jack Hills, Western Australia
2018, Earth and Planetary Science LettersCitation Excerpt :Weiss et al. (2015) call for a pervasive 1 Ga overprint (i.e., an overprint that is seen everywhere). We have serious concerns with respect to the methods and interpretations of the Weiss et al. (2015) study and their reply (Weiss et al., 2016) to comments pointing out problems with their work (Bono et al., 2016). These include remaining data inconsistencies that indicate unrecognized errors [see Bono et al. (2016), and Supplementary Materials SM1].
