Scientists know that manganese, in its various oxide forms, plays a significant role in Earth's geochemical cycles. However, ...

4.5 billion years ago was an interesting time for Earth. The atmosphere was thick and what we would now think of as toxic. The moon, which was freshly formed, looks much more massive than it does ...

Researchers have found that Earth formed within an unusually narrow range of oxygen conditions that kept both phosphorus and nitrogen available for life. That constraint reframes habitability as a ...

This photo taken and beamed back to Earth autonomously by a mini rover released from the lander-ascender combination of Chang'e 6 probe shows a view of the combination itself on the lunar surface, ...

The oxygen fugacity (fO(2)) at which carbonate-bearing melts are reduced to either graphite or diamond in synthetic eclogite compositions has been measured in multi-anvil experiments performed at ...

Nakhlites are a unique suite of ~20 Martian meteorites. They are basaltic pyroxenites with mineralogies dominated by cumulative pyroxene and olivine. Traditionally considered to represent a shallow ...

Oxygen fugacity controls the occurrence of multi-valence ions (iron, carbon, ect.), so it is a critical factor affecting the geochemical and geophysical properties of martian mantle. After dozens of ...

Abstract: We have developed and validated a statistical model to estimate the partial pressure (or fugacity) of carbon dioxide at the sea surface from space-based observations of sea surface ...

Researchers have introduced the “potential oxygen fugacity” parameter to track the evolution of Earth’s mantle and atmosphere, showing that mantle cooling, rather than intrinsic fO2 changes, ...

Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...
