Subduction-driven volatile recycling: A global mass balance
Volatile elements (water, carbon, nitrogen, sulfur, halogens, and noble gases) played an
essential role in the secular evolution of the solid Earth and emergence of life. Here we …

The diverse planetary ingassing/outgassing paths produced over billions of years of magmatic activity
The CHONS elements that constitute the outgassed atmosphere and exosphere have likely
been delivered by chondritic materials to the Earth during planetary accretion and …

Carbon concentration increases with depth of melting in Earth's upper mantle
Carbon in the upper mantle controls incipient melting of carbonated peridotite and so acts as
a critical driver of plate tectonics. The carbon-rich melts that form control the rate of volatile …

Carbon budget of Earth's deep mantle constrained by petrogenesis of silica-poor ocean island basalts
The convecting mantle is the Earth's largest carbon reservoir that controls the carbon outflux
from the interior to surface, but its carbon content remains largely uncertain due to limited …
