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

While the former is unavoidable, the latter amounts to self-inflicted wounds that may have forestalled scientific progress.

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

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
