Oil-pollution due to accidental during transportation or leakage from storage not only brings large damage to the environments, but it also affects the geotechnical properties of soil. Hence, an extensive laboratory testing program was carried out to investigate the geotechnical properties on palm biodiesel contaminated weathered granite soil and mining sand. A series of laboratory experiments ...

In situ radionuclide migration experiments, followed by excavation and sample characterization, were conducted in a water-conducting shear zone at the Grimsel Test Site (GTS) in Switzerland to study migration paths of radionuclides in fractured granite. In this work, a micro-scale mapping technique was applied by interfacing laser ablation sampling with inductively coupled plasma-mass spectrome...

the study area is located south of ghonabad in eastern iran. this area is situated between two major faults, darouneh to the north and dashtbyaz to the south. the movements of these faults cased major dislocation of this block. najmabad granodiorite to granite batholith is elongated trending east-west 2×8 km2. mineralization is associated with granite and monzonite. alteration zones are: propyl...

mard-abad calc-alkaline granite formed along the margin of active pull-apart or intra-continental plates, and it is post-collision granite type. granophyric, perthitic and myrmekitic are main textures that could form from crystallization of hypersolvus source magma, which occurred under water vapor pressure of approximately 2 kb. during this study the temperature of formation of these granites ...

In order to reveal the metallogenic potential of Indosinian Ziyunshan granite in central Hunan, temporal, spatial and genetic relationship between mineralization is discussed, concentrations ore-forming elements for different granites are measured. The geochemistry elements, isotope chronology, data derived from analysis on Au-W deposit area compared with geologic features regional rock. result...

Small samples of rock, like those used in laboratory collision experiments, are known to be much stronger than bodies that are meters to hundreds of meters in size [1]. Specifically, the impactor energy per unit target mass needed to shatter the target decreases dramatically with increasing target size. This occurs because the strength of rock, like many other geological materials, depends stro...

Three techniques of holographic Interferometry were developed to study the response of geological materials to propagating stress waves. Two of these techniques, stored-beam Interferometry and double-exposure Interferometry, were found effective when applied to studying smallamplitude wave propagation. The third technique, a form of time-average holographic Interferometry (which produces fringe...
