A Model for the PTX Properties of H2O-NaCl
… compositions that are approximated by the H₂O-NaCl system. When minerals grow in the presence of such fluids, some of the solution is trapped in the growing mineral as fluid inclusions. The salinity, temperature of homogenization, and pressure of homogenization are required to predict the …

Low Temperature Phase Relations in the System H2O-NaCl-FeCl2
The low temperature phase behavior of the system H2O-NaCl-FeCl2 was examined using synthetic fluid inclusions. Experiments were conducted along the 5 wt% NaCl (relative to the total solution) pseudobinary, with FeCl2 concentrations varying from 2 to 33 wt%, and along the pseudobinary defined by …

Fluid evolution in the nepheline syenites of the Ditrău Alkaline Massif, Transylvania, Romania
… The fluids, in most cases, can be modeled by the H2O-NaCl system with various NaCl contents; however inclusions with more complex fluid (containing also K, Ca, CO3, etc. besides H2O and NaCl) composition are abundant. Raman spectroscopic studies of daughter minerals in inclusions demonstrate the …

Charakterisierung und Quantifizierung thermischer und diagenetischer Prozesse im karbonischen Akkretionsprisma in Nordchile
… repräsentiert. Das peak-metamorphe Fluid ist ein H2O-CO2-NaCl-dominiertes Fluid mit CH4±H2S. Ein H2O-NaCl-Fluid war über weite Bereiche der p-T-Geschichte der Chañaral-Mélange aktiv. Als Zeugen eines jüngeren Systems werden Einschlüsse mit CO2-CH4±H2S±N2 angesehen. Die Chañaral-Mélange …

Thermodynamics of geologic fluids
… vaporsaturated liquidus relations of the system H2O-NaCl-CaCl2 have been modeled to allow estimation of fluid inclusion compositions by either microthermometric or microanalytical methods. Carbon capture and storage (CCS) in deep saline formations represents one option for reducing anthropogenic …

A Study of Petrography, Fluid Inclusions and Graphite Alteration of the Phoenix Uranium Deposit, Athabasca Basin, Northern Saskatchewan, Canada
… fluids in QBSN2, QBSN3 and QBSM4 belong to the H2O-NaCl-CaCl2 ± MgCl2 fluid system. The liquid-dominant inclusions in QBSN2 are interpreted to represent homogeneous trapping of the liquid phase show a high salinity of 27.9 wt% (NaCl+CaCl2; same for all the salinity values unless otherwise …

Characterization of Fluids Associated with Vein-type Uranium Mineralization in the Beaverlodge Uranium District, Northern Saskatchewan: Field, Petrographic, Fluid Inclusion and C-O Isotope Studies
… to 250oC), and salinities from 0.2 to 30.8 wt% NaCl equivalent (clustered in two ranges, 0.2-5.9 wt% NaCl equiv and 18.2-30.8 wt% NaCl equiv). The average homogenization temperature of liquid-dominated inclusions in quartz from the mineralized veins of one deposit (Hab, 231.5oC) is very similar …

Mineral, fluid and thermal evolution in veins from late orogenic coal basins of the Cantabrian Zone (Variscan, NW Spain)
… from a heterogeneously trapped, immiscible H2O-CH4 -CO2 (± NaCl) fluid mixture. P-T conditions evolved from 73 °- 110 °C and 15-56 MPa to 87 °-129 °C and 10-27 MPa. At a late stage of quartz growth saddle dolomite precipitated. Materials for mineral precipitation were derived locally from …

Computational Modeling of Osmotically Assisted Membrane Separations with Multicomponent Solution-diffusion Theory
… each solute present in the separation. Using the H2O-NaCl-EtOH forward osmosis processes as a case study, we demonstrate the model’s robustness in regressing water and solute fluxes across a wide range of concentrations. The AAD of the solution-diffusion model reduced from 66.1 % to 7.2 % over a …

Exploring two-phase hydrothermal circulation at a seafloor pressure of 25 MPa: Application for EPR 9°50′N
… momentum, energy, and salt conservation in a NaCl-H2O fluid to model the seafloor hydrothermal processes. These simulations use homogeneous box geometries at a fixed seafloor pressure of 25 MPa with constant bottom temperature boundary conditions that represent a sub-axial magma chamber to …
