The crust of the Kaapvaal craton accreted throughout the Archaean over nearly 1 billion
years. It provides a unique example of the various geological processes that shape Earth's …

Plate tectonics is a fundamental factor in the sustained habitability of Earth, but its time of
onset is unknown, with ages ranging from the Hadaean to Proterozoic eons,–. Plate motion …

Due to the scarcity of rock samples, the Hadean Era predating 4 billion years ago (Ga)
poses challenges in understanding geological processes like subaerial weathering and …

The nature of Earth's earliest crust and crustal processes remain unresolved questions in
Precambrian geology. While some hypotheses suggest that plate tectonics began in the …

The tectonic affiliations and magma compositions that formed Earth's earliest crusts remain
hotly debated. Previous efforts toward this goal have relied heavily on determining the …

Detrital heavy minerals have helped address geologically complex issues such as the
nature and origin of the early terrestrial crust, the growth and evolution of the continental …

Zircon trace element geochemistry has become an increasingly popular tool to track crustal
evolution through time. This has been especially important in early-Earth settings where …

With plate tectonics operating on Earth, the preservation potential for mantle reservoirs from
the Hadean Eon (> 4.0 Ga) has been regarded as very small. The quest for such early …

Determining the mechanisms by which the earliest continental crust was generated and
reworked is important for constraining the evolution of Earth's geodynamic, surface, and …

Subduction is a key geodynamic feature on modern Earth that drives crustal chemical
diversity, bridging the atmo-, hydro-, and lithosphere, but remains an enigmatic, unique …
