Deciphering the Age and Signifiance of the Cora Lake Shear Zone: Athabasca Granulite Terrane, Northern Saskatchewan
Deciphering the Age Significance the Cora Lake Shear Zone Athabasca Granulite Terrane Northern Saskatchewan
2014/10/21
Interpreting the tectonic significance of high strain zones requires detailed knowledge of the P-T-t-D history of rocks on either side and of tectonized rocks within the shear zone. In-situ monazite g...
Validity of the Refraction Microtremors (ReMi) Method for Determining Shear Wave Velocities for Different Soil Types in Egypt
Refraction Microtremors ReMi Crosshole Downhole Shear Wave Egypt
2013/3/7
The Refraction Microtremor (ReMi) method is being used around the world by the geotechnical and geophysical community to determine shear-wave velocities. This is due to its faster, less expensive and ...
Effects of Polypropylene Fibers on the Shear Strength of Sandy Soil
Sand Fibers Angle of Internal Friction Shear Strength Aspect Ratio
2013/3/6
This paper presents the effect of two types of polypropylene fibers on shear strength parameters of sandy soil. To achieve the goals of this research, a sandy soil was obtained from a depth of 40 cm f...
The pecularities of shear crack pre-rupture evolution and distribution of seismicity before strong earthquakes
shear crack pre-rupture evolution seismicity strong earthquakes
2009/12/9
Several methods are presently suggested for investigating pre-earthquake evolution of the regions of high tectonic activity based on analysis of the seismicity spatial distribution. Some precursor sig...
Comparative numerical and analogue shear box experiments and their implications for the mechanics along the failure plane of landslides
Comparative numerical analogue shear box experiments failure plane of landslides
2009/12/3
It has long been known that failure of soils is controlled by intrinsically weak mineral phases (such as clays) and transient pore pressure fluctuations.Both factors may be involved in triggering of s...
Near surface shear wave velocity in Bucharest,Romania
Near surface shear wave velocity Bucharest
2010/1/4
Bucharest, the capital of Romania with nearly 2 1/2 million inhabitants, is endangered by the strong earthquakes in the Vrancea seismic zone. To obtain information on the near surface shear-wave veloc...
