Safe exploitation of high-enthalpy geothermal fields for energy production requires knowledge the mechanical behavior faults and seismic cycle in presence hot, pressurized fluids. In reservoirs, fluids can exist liquid, liquid-vapor mixture, vapor, or supercritical fluid state. Here we investigate frictional properties simulated fault gouges derived from main stratigraphic units present Krafla Geothermal Field (Iceland) under realistic water temperature (Tf=100-400˚C) pressure...
Although nephrite jade has been collected and treasured since the Stone Age, we lack a clear understanding of how it forms during deformation metasomatism in shear zones. Using microstructural analysis samples from Taiwan, California, New Zealand, propose conceptual model for evolution that distinguishes four types based on mode formation textural characteristics: (1) primary (type 1a) or folded 1b) vein nephrite, (2) crenulated 2), (3) foliated semi-nephrite 3), (4) nodular domainal 4). We...
Fault’s frictional strength and particularly its ability to heal during the interseismic period (fault healing Δμ) is critical understand seismic cycle, yet understanding of temperature phase-dependent characteristics natural geothermal conditions remains limited. Here we examined both simulated fresh chlorite-altered basaltic gouge from Krafla field (Iceland) under realistic water Tf = 100-400 ˚C pressure Pf 10-30 MPa (water in liquid, vapor...
<p>Olivine and enstatite, formed by dehydroxylation of serpentine, have been naturally experimentally documented as evidence paleo-earthquake rupture propagation within natural serpentinite-bearing slip zones. To investigate the rheological textural evolution during serpentinite, we performed rotary-shear friction experiments on water-saturated serpentinite powders using drained undrained conditions (where allow for excess fluid pressure to escape gouge holder). Using a...
