Why Hadean?,ing of that time included the possibility that our planet had forever existed in a quasi-steady state. By the later part of that century, it was broadly understood that Earth must have experienced a discrete origin but that details of that event might never be discerned. The advent of radiometric da

Thermal Evolution Models, with missteps related to as yet undiscovered physics or fundamentally incorrect assumptions. While the former is unavoidable, the latter amounts to self-inflicted wounds that may have forestalled scientific progress. Even in the absence of knowledge of initial conditions, linear mathematical relati

Radionuclide Produced Isotopic Variations in Mantle Rocks,ryos during runaway accretion that occurred within 1–10 Ma of formation of the first solar system solids at 4.567 ± 0.001 Ga. Both long- and short-lived radionuclides leave isotopic signatures in mantle rocks that bear on when and how the silicate Earth formed and differentiated. The longstanding vi

Models of Continental Growth and Destruction,ere is widespread agreement that plate tectonics has been doing just that for at least the past billion years. We also don’t fully understand the structure of the continental crust; popular layered models lack mechanisms to produce such structures or to recover them following tectonic homogenization

Plate Boundary Interactions Through Geologic History,plate tectonics from operating at 4.3 Ga, evidence that it was is indirect. Although subduction initiation is a robust feature of the modern plate tectonic system and we can calculate with some accuracy when oceanic lithosphere attains negative buoyancy, we don’t yet understand how strong the lithos
