The chemistry of carbon in aqueous fluids at extreme pressure and temperature conditions is of great importance to Earth's deep carbon cycle, which substantially affects the carbon budget at Earth's surface and global climate change. At ambient conditions, the concentration of carbonic acid in water is negligible, so aqueous carbonic acid was simply ignored in previous geochemical models. However, by applying extensive ab initio molecular dynamics simulations at pressure and temperature… Expand

Carbon dioxide, bicarbonate and carbonate ions in aqueous solutions under deep Earth conditions.
First-principles molecular dynamics simulations provide mechanistic insight into the hydration shell of carbon dioxide, bicarbonate and carbonate ions, and into the pathways of the acid/base reactions that convert these carbon species into one another in aqueous solutions. Expand
Spectroscopic evidence for intact carbonic acid stabilized by halide anions in the gas phase.
A qualitative correlation is found between these structural motifs and the constituent acid pKa values, strongly suggesting that pKa is a more suitable factor to predict correct acid-base chemistry between these diprotic oxyacids and halides. Expand


The Chemistry of Carbon in Aqueous Fluids at Crustal and Upper-Mantle Conditions: Experimental and Theoretical Constraints
Carbon can be a major constituent of crustal and mantle fluids, occurring both as dissolved ionic species (e.g., carbonate ions or organic acids) and molecular species (e.g., CO2, CO, CH4, and moreExpand
The fate of carbon dioxide in water-rich fluids under extreme conditions
Contrary to popular geochemical models assuming that molecular CO2(aq) is the major carbon species present in water under deep Earth conditions, it is found that at 11 GPa and 1000 K, carbon exists almost entirely in the forms of solvated carbonate (CO32−) and bicarbonate (HCO3−) ions. Expand
In situ Raman study and thermodynamic model of aqueous carbonate speciation in equilibrium with aragonite under subduction zone conditions
Abstract Carbonate minerals may be recycled into the mantle at subduction zones. However, the evolution of carbonate minerals in equilibrium with aqueous fluids as well as the nature of the chemicalExpand
Dielectric properties of water under extreme conditions and transport of carbonates in the deep Earth
It is found that MgCO3 (magnesite)—insoluble in water under ambient conditions—becomes at least slightly soluble at the bottom of the upper mantle, suggesting that water may transport significant quantities of oxidized carbon and the Earth’s deep carbon could possibly be recycled through aqueous transport through subduction zones.

The water-carbon dioxide miscibility surface to 450 °C and 7 GPa
Fluid-fluid immiscibility in the water-carbon dioxide binary system has been measured to a pressure of 7 GPa and temperature of 450 °C, providing the first such data under conditions overlappingExpand
Stable solid and aqueous H2CO3 from CO2 and H2O at high pressure and high temperature
It is found that, contrary to present understanding, neutral H2CO3 is a significant component in aqueous CO2 solutions above 2.4 GPa and 110 °C as identified by IR-absorption and Raman spectroscopy. Expand
Water-carbon dioxide solid phase equilibria at pressures above 4 GPa
A solid phase in the mixed water-carbon dioxide system, previously identified as carbonic acid, was observed in the high-pressure diamond-anvil cell. The pressure-temperature paths of both itsExpand
Extended Deep Earth Water Model for predicting major element mantle metasomatism
Abstract Fluids in the deep crust and upper mantle appear to have played roles in the long-term evolution of the subcratonic lithospheric mantle and the stabilities of the continents, in theExpand
Equations of state for aqueous solutions under mantle conditions
With unique physical and chemical properties, aqueous solutions in the mantle may play important roles for a number of geochemical and geodynamical processes. However, since experimental dataExpand
Reevaluating carbon fluxes in subduction zones, what goes down, mostly comes up
Carbon fluxes in subduction zones can be better constrained by including new estimates of carbon concentration in subducting mantle peridotites, consideration of carbonate solubility in aqueous fluid along subduction geotherms, and diapirism of carbon-bearing metasediments. Expand
