Brittle Deformation of Damaged Mafic and Ultramafic Rocks and Their Implications on Plate Bending

“…Subsequently, the strain gauges were glued parallel to each other on the polished cylindrical surface, and the transducers for measuring velocity were glued in the direction normal to the strain gauges. In the current investigation, to ensure full saturation, we pre-saturated the prepared samples for 10 days, by dipping them in a 0.5 mol/l NaCl solution, as it is proven sufficient by Nagase et al (2020). The deformation experiments were conducted under a confining pressure of 30 MPa and an effective pressure of 20 MPa to ensure brittle deformation.…”

Elastic Properties of Thermally Treated Diabase and Peridotite: Implications Toward the Elastic Properties of Oceanic Lithosphere

“…The enhanced porosity was later estimated by the weight difference between the saturated and dry samples and the solid volume measured by a pycnometer. In our analysis, we utilized the impregnation method to saturate the sample (Nagase et al., 2020), where the sample is vacuumed in a closed system prior to soaking in water, which is opposed to the imbibition method where the soaked sample system is vacuumed. Following the porosity estimation, the samples were stored in a furnace under 70°C until assembled for experiments.…”
