Exploring Trends in Microcrack Properties of Sedimentary Rocks: An Audit of Dry and Water Saturated Sandstone Core Velocity–Stress Measurements
Compliance Ratio Microcrack Properties Saturated Stress Dependent Velocities Ultrasonic
2013/3/11
Stress dependent rock physics models are being used more routinely to link mechanical deformation and stress perturbations to changes in seismic velocities and seismic anisotropy. In this paper, we in...

Single-grain detrital muscovite Rb-Sr isotopic composition as an indicator of provenance for the Carboniferous sedimentary rocks in northern Dabie, China
Dabie detrital muscovite provenance single-grain Rb-Sr dating
2017/8/9
Low-grade metamorphic Paleozoic sedimentary rocks are exposed along the northern margin of the Qinling-Dabie orogenic belt that formed by the collision of the North and South China blocks during the E...
Non-linear Stress-strain Relation in Sedimentary Rocks and Its Effect on Seismic Wave Velocity
the stress-strain relations microplasticity hysteresis the strain-amplitude dependence nonlinear wave propagation
2009/6/9
Character of the stress-strain relation σ(ε) of sedimentary rocks depends on the strain level in a range of ε~10-6÷10-3. Nonlinearity and a hysteresis in the σ(ε) are caused by microplasticity. Static...
