The Eoarchean Muzidian gneiss complex: Long-lived Hadean crustal components in the building of Archean continents
D Wang, XF Qiu, RW Carlson - Earth and Planetary Science Letters, 2023 - Elsevier
The nature of Earth's first crust and the processes that formed it are poorly constrained due
to limited exposures of> 3.7 billion-year-old (Ga) rocks. Here we report the discovery of a …

Titanium isotopes constrain a magmatic transition at the Hadean-Archean boundary in the Acasta Gneiss Complex
Plate subduction greatly influences the physical and chemical characteristics of Earth's
surface and deep interior, yet the timing of its initiation is debated because of the paucity of …

The tungsten-182 record of kimberlites above the African superplume: Exploring links to the core-mantle boundary
Many volcanic hotspots are connected via 'plume'conduits to thermochemical structures with
anomalously low seismic velocities at the core-mantle boundary. Basaltic lavas from some of …

The komatiite testimony to ancient mantle heterogeneity
Komatiites are crystallized samples of high-temperature, high-MgO lavas that were common
during the Archean, but became increasingly rarer in the Proterozoic and Phanerozoic …

The chemistry of fine-grained terrigenous sediments reveals a chemically evolved Paleoarchean emerged crust
The nature of the rocks exposed to weathering and erosion on continents exerts an
important control on weathering feedbacks and the supply of nutrients to the oceans. It also …

Detrital zircon evidence for change in geodynamic regime of continental crust formation 3.7–3.6 billion years ago
The nature of the early terrestrial crust and how it evolved through time remains highly
controversial. Whether conventional plate tectonics operated in the Hadean and early …
