“…The greenstone belts consist of mafic and ultramafic extrusive volcanic rocks and their high‐level intrusive equivalents along with interstratified volcaniclastic, clastic, carbonate, and chemical sedimentary rocks. The well‐preserved greenstone successions in the Pilbara and Kaapvaal cratons are built up by multiple cycles of igneous activity and sedimentation extending over 100s of millions of years and are up to 1000s of meters thick (G. R. Byerly et al., 2019b; Hickman, 2012; Kemp et al., 2023; Van Kranendonk, Smithies, et al., 2019). The igneous rocks include komatiites, komatiitic basalts, basalts, and basaltic andesites along with variable volumes of dacite and rhyolite (e.g., Van Kranendonk, Smithies, et al., 2019).…”

Our planet is unique in the solar system in having a bimodal distribution of crustal types (continental and oceanic), the presence of liquid water at its surface, an oxygenated atmosphere, and a prolific and diverse biosphere. The evolving yet linked nature of these elements, across the range of spatial and temporal scales that operate on the planet, indicates complex and dynamic cycling between the solid (lithosphere, mantle, and core) and surficial (oceans, atmosphere, and biosphere) reservoirs. This linked evolution occurs in response to heat dissipation from the planet's interior, modulated by input of solar energy to the surficial reservoirs. During its very early history the Earth lacked these crustal and surficial features and, after initial accretion from the solar nebula, likely consisted of a magma ocean (e.g., Elkins-Tanton, 2012). Cooling, density settling, and crystallization resulted in rapid differentiation of the Earth, perhaps over a few tens of millions of years, and included formation of core, mantle, proto-crust, and atmosphere (Figure 1; Elkins-Tanton, 2008.
