Oxygenation, life, and the planetary system during Earth's middle history: An overview
The long history of life on Earth has unfolded as a cause-and-effect relationship with the
evolving amount of oxygen (O2) in the oceans and atmosphere. Oxygen deficiency …

The geologic history of primary productivity
The rate of primary productivity is a keystone variable in driving biogeochemical cycles
today and has been throughout Earth's past. 1 For example, it plays a critical role in …

Origin-of-life molecules in the atmosphere after big impacts on the early Earth
The origin of life on Earth would benefit from a prebiotic atmosphere that produced nitriles,
like HCN, which enable ribonucleotide synthesis. However, geochemical evidence suggests …

Oxygenation of Earth's atmosphere induced metabolic and ecologic transformations recorded in the Lomagundi-Jatuli carbon isotopic excursion
The oxygenation of Earth's atmosphere represents the quintessential transformation of a
planetary surface by microbial processes. In turn, atmospheric oxygenation transformed …

The Laramide orogeny: Current understanding of the structural style, timing, and spatial distribution of the classic foreland thick-skinned tectonic system
The Laramide foreland belt comprises a broad region of thick-skinned, contractional
deformation characterized by an anastomosing network of basement-cored arches and …

Inverse methods for consistent quantification of seafloor anoxia using uranium isotope data from marine sediments
Uranium isotopes (δ 238 U) have quickly become one of the most widely-used redox proxies
in paleoceanographic studies. The quantitative power of the δ 238 U proxy derives from the …

Characteristics of the carbon cycle in late Mesoproterozoic: Evidence from carbon isotope composition of paired carbonate and organic matter of the Shennongjia …
Abstract The late Mesoproterozoic Era (1300–1000 Ma) was a critical period that witnessed
the origin and early evolution of multicellular eukaryotes. Multiple studies have reported …

EONS: A new biogeochemical model of Earth's oxygen, carbon, phosphorus, and nitrogen systems from the Archean to the present
Abstract We present Earth's Oxygenation and Natural Systematics (EONS): a new, fully
coupled biogeochemical model of the atmosphere, ocean, and their interactions with the …
