Secular evolution of continents and the Earth system
Understanding of secular evolution of the Earth system is based largely on the rock and
mineral archive preserved in the continental lithosphere. Based on the frequency and range …

The supercontinent cycle
Supercontinents signify self-organization in plate tectonics. Over the past~ 2 billion years,
three major supercontinents have been identified, with increasing age: Pangaea, Rodinia …

The evolution of the continental crust and the onset of plate tectonics
The Earth is the only known planet where plate tectonics is active, and different studies have
concluded that plate tectonics commenced at times from the early Hadean to 700 Ma. Many …

Phosphorus availability on the early Earth and the impacts of life
Phosphorus (P) is critical to modern biochemical functions and can control ecosystem
growth. It was presumably important as a reagent in prebiotic chemistry. However, on the …

Signatures of early microbial life from the Archean (4 to 2.5 Ga) eon
K Lepot - Earth-Science Reviews, 2020 - Elsevier
Abstract The Archean era (4 to 2.5 billion years ago, Ga) yielded rocks that include the
oldest conclusive traces of life as well as many controversial occurrences. Carbonaceous …

Reconstructing Earth's atmospheric oxygenation history using machine learning
Reconstructing historical atmospheric oxygen (O2) levels at finer temporal resolution is a top
priority for exploring the evolution of life on Earth. This goal, however, is challenged by gaps …

Earth's Great Oxidation Event facilitated by the rise of sedimentary phosphorus recycling
The rise of atmospheric oxygen during the Great Oxidation Event some 2.4 billion years ago
was a defining transition in the evolution of global biogeochemical cycles and life on Earth …

A pulse of oxygen increase in the early Mesoproterozoic ocean at ca. 1.57–1.56 Ga
The relationship between oxygen and evolution of early eukaryotes including algae and
primitive animals in geological history has been debated, partly due to the varying estimates …

Ediacaran reorganization of the marine phosphorus cycle
TA Laakso, EA Sperling… - Proceedings of the …, 2020 - National Acad Sciences
The Ediacaran Period (635 to 541 Ma) marks the global transition to a more productive
biosphere, evidenced by increased availability of food and oxidants, the appearance of …

The grandest of them all: the Lomagundi–Jatuli Event and Earth's oxygenation
The Paleoproterozoic Lomagundi–Jatuli Event (LJE) is generally considered the largest, in
both amplitude and duration, positive carbonate C-isotope (δ 13Ccarb) excursion in Earth …
