The geology of Earth and super‐Earth sized planets will, in many cases, only be observable via their atmospheres. Here, we investigate secondary volcanic atmospheres as a key base case of how atmospheres may reflect planetary geochemistry. We couple volcanic outgassing with atmospheric chemistry models to simulate the growth of C‐O‐H‐S‐N atmospheres in thermochemical equilibrium, focusing on what information about the planet's mantle fO2 and bulk silicate H/C ratio could be determined by… 

Growth and Evolution of Secondary Volcanic Atmospheres: II. The Importance of Kinetics

Volcanism is a major and long-term source of volatile elements such as C and H to Earth’s atmosphere, likely has been to Venus’s atmosphere, and may be for exoplanets. Models simulating volcanic

Contrasting Volcanic Deformation in Arc and Ocean Island Settings Due To Exsolution of Magmatic Water

Two of the most widely observed co‐eruptive volcanic phenomena—Ground deformation and volcanic outgassing—Are fundamentally linked via the mechanism of magma degassing and the development of

Sources of Nitrogen-, Sulfur-, and Phosphorus-Containing Feedstocks for Prebiotic Chemistry in the Planetary Environment

Biochemistry on Earth makes use of the key elements carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur (or CHONPS). Chemically accessible molecules containing these key elements would

Mantle redox state drives outgassing chemistry and atmospheric composition of rocky planets

The mantle redox state is central to the chemical composition of atmospheres while factors such as planetary mass, thermal state, and age mainly affect the degassing rate, and it is demonstrated that mantle oxygen fugacity has an effect on atmospheric thickness.

Creation and Evolution of Impact-generated Reduced Atmospheres of Early Earth

The origin of life on Earth seems to demand a highly reduced early atmosphere, rich in CH4, H2, and NH3, but geological evidence suggests that Earth's mantle has always been relatively oxidized and

The oxidation state of Hadean magmas and implications for early Earth’s atmosphere

A redox-sensitive calibration to determine the oxidation state of Hadean magmatic melts is reported, finding that the melts have average oxygen fugacities that are consistent with an oxidation state defined by the fayalite–magnetite–quartz buffer, similar to present-day conditions.

Heterogeneity in mantle carbon content from CO2-undersaturated basalts

The results indicate that the upper mantle carbon content is highly heterogeneous, varying by almost two orders of magnitude globally, with the potential to produce large geographic variations in melt fraction below the volatile-free solidus.

Evidence for a reducing Archean ambient mantle and its effects on the carbon cycle

Chemical reduction-oxidation mechanisms within mantle rocks link to the terrestrial carbon cycle by influencing the depth at which magmas can form, their composition, and ultimately the chemistry of
