Glacial reworking of paraglacial rock slope material has been inferred from long-deglaciated terrains to be an important component of glacial sediment transfer. We provide the first description from a contemporary glacial environment of the geomorphological consequences of glacier advance (of the Feegletscher Nord, Switzerland) across a paraglacial rock avalanche deposit. The landform-sediment ...

Due to the insufficiency of damage model, on the basis of studying deeply deformation and damage mechanism of the rock mass, considering the process and phenomenon of the damage of rock mass, damage part can be divided into two parts: the damage material and micro defects due to the change of damage material, then this paper puts forward a new definition of damage. Besides it proposes an impact...

an important concern in rock mechanics is non-homogeneity as joints or fault. this noticeable feature of failures in rock is appearance of slip surfaces or shear bands, the characteristics of that are associated with deformation being concentrated in a narrow zones and the surrounding material remaining intact. adopting the joints as fractures, fractures are well known for their effects on the ...

Expressionist Painting: City Landscape City Landscape depicts a nonrepresentational scene.8 A sense of entrapment (or a means of escape) is felt as the applied and colorful paint appears to leak out from the central part of the support. Loosely constructed geometric shapes recall a rock-like surface, which enclose and frame the color within and assist the eye inward toward the colorful scene. E...

our civilization is based on metals, among other life supports. the existing ore deposits are becoming rapidly depleted by almost exponentially increasing demand and production and major new ore discoveries are needed. mineral exploration is supported by modern tools and scientific ideas, but geological characteristics of orebodies and their rock associations have still to be visualized.the tim...

in this paper, after collecting the rock samples from eight mines and one high way slope, the tests for determination of dry density, uniaxial compressive strength, tensile strength (brazilian test), elastic modulus, schmidt hammer rebound number have been done on samples. in addition, in order to calculating the mean size of rock grains, quartz content, hardness and abrasivity, a thin sections...
