An Experimental Study on Kinetics-Controlled Ca-Carbonate Aqueous Reduction into CH4 (1 and 2 GPa, 550°C): Implications for C Mobility in Subduction Zones
Autor: Weigang Peng, Simone Tumiati, Lifei Zhang, Carla Tiraboschi, Alberto Vitale Brovarone, Luca Toffolo, Stefano Poli
Publikováno v: Journal of Petrology. 63
Abiotic methane (CH4) generation under subduction zone conditions has been experimentally investigated through aqueous reduction of pure C-bearing materials (e.g. carbonate minerals and organic matter). However, quantitative assessments of CH(4 )prod

Carbon-saturated COH fluids in the upper mantle: what ex situ experiments tell us about carbon at high-pressure and high-temperature conditions
Autor: Carla Tiraboschi
High-pressure COH fluids have a fundamental role in a variety of geological processes. Their composition in terms of volatile species can control the solidus temperature, carbonation/decarbonation reactions, and influences the amount of solutes gener

Solubility of magnetite-hematite assemblages in slab-derived saline fluids
Autor: Carla Tiraboschi, Carmen Sanchez-Valle
In subduction zones, aqueous fluids derived from devolatilization processes of the oceanic lithosphere and its sedimentary cover, are major vectors of mass transfer from the slab to the mantle wedge and contribute to the recycling of elements and to

Dissolution susceptibility of glass-like carbon versus crystalline graphite in high-pressure aqueous fluids and implications for the behavior of organic matter in subduction zones
Autor: Simone Tumiati, Sula Milani, Alberto Vitale-Brovarone, Carla Tiraboschi, Francesca Miozzi, Stefano Poli, Craig E. Manning, Dimitri A. Sverjensky
Organic matter, showing variable degrees of crystallinity and thus of graphitization, is an important source of carbon in subducted sediments, as demonstrated by the isotopic signatures of deep and ultra-deep diamonds and volcanic emissions in arc se

Experimental determination of magnesia and silica solubilities in graphite-saturated and redox-buffered high-pressure COH fluids in equilibrium with forsterite + enstatite and magnesite + enstatite
Autor: Dimitri A. Sverjensky, Peter Ulmer, Carla Tiraboschi, Thomas Pettke, Stefano Poli, Simone Tumiati
Publikováno v: Tiraboschi, Carla; Tumiati, Simone; Sverjensky, Dimitri; Pettke, Thomas; Ulmer, Peter; Poli, Stefano (2018). Experimental determination of magnesia and silica solubilities in graphite-saturated and redox-buffered high-pressure COH fluids in equilibrium with forsterite + enstatite and magnesite + enstatite. Contributions to mineralogy and petrology, 173(1) Springer 10.1007/s00410-017-1427-0
We experimentally investigated the dissolution of forsterite, enstatite and magnesite in graphite-saturated COH fluids, synthesized using a rocking piston cylinder apparatus at pressures from 1.0 to 2.1 GPa and temperatures from 700 to 1200 °C. Synt

Estimates of dissolved CO2 in subduction-zone fluids are based on thermodynamic models, relying on a very sparse experimental data base. Here, we present experimental data at 1–3 GPa, 800 °C, and ∆FMQ ≈ −0.5 for the volatiles and solute cont
