Plate tectonics, involving a globally linked system of lateral motion of rigid surface plates, is a characteristic feature of our planet, but estimates of how long it has been the modus …
Studies investigating the structure and diversity of Earth's record of life older than 3.2 Ga are restricted to two locations worldwide in which sedimentary rocks have escaped regional …
The colonization of emergent continental landmass by microbial life was an evolutionary step of paramount importance in Earth history. Here we report direct fossil evidence for life …
How and when continents grew and plate tectonics started on Earth remain poorly constrained. Most researchers apply the modern plate tectonic paradigm to problems of …
Iron is a remarkable element in its relatively high abundance for its mass and its sensitivity to (and control of) redox on a planetary scale over geologic time. Numerous volumes have …

Microbial life was well established and widespread by the Paleoarchean; however, the degree of evolutionary advancement such as microbial motility, intra-and inter-species …
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 …
Precambrian banded iron formations (BIF) are chemical sedimentary deposits whose trace element signatures have been widely used to interrogate the chemical composition and …
Structural analysis of a proposed Mesoarchean suture located immediately to the southwest of the Barberton Greenstone Belt, South Africa–known as the Inyoni Shear Zone (ISZ) …
