  1. Physical and chemical aspects of fluid evolution in hydrothermal ore systems

    … used to simulate the effect of boiling on silica precipitation in geothermal and epithermal precious metal systems. The extent to which decreasing temperature and fluid vaporization are responsible for quartz precipitation is dependent on three related factors - the temperature of the fluid …

  2. Geology and geochemistry of the Bully Hill area of the East Shasta district, Shasta County, California.

    … of NaCO, CaO, and Fe₂O₃* , and the assemblage quartz + sericite + pyrite. Quartz precipitation in the upper portion of the zones led to cyclic sealing of fluid flow, rupturing of the seal, quartz supers aturation, focused fluid discharge, and formation of sulfide mounds on the seafloor. …

  3. Thermodynamics of geologic fluids

    … in deep saline formations. Numerical modeling of quartz dissolution and precipitation in a sub-seafloor hydrothermal system was used to understand the role of fluid-phase immiscibility ("boiling") on quartz-fluid interactions, and to predict where in the system quartz could deposit and trap fluid …

  4. Geomechanical aspects of fracture growth in a poroelastic, chemically reactive environment

    … between the slow fracture opening rate and quartz precipitation rate will affect the effective permeability and porosity of the naturally fractured reservoir. However, the competition is trivial in high-permeability rocks. Other factors, such as reservoir boundary condition, layer thickness, …
