This paper reviews the literature on dyking as a mechanism of felsic magma extraction from a source and transport to shallower crustal levels, and review the recent literature suggesting a range of alternative mechanisms of magma migration in hot crustal zones which produce mesoscale pervasive granite sheet intrusions. Recent papers have strongly favoured dyking as the main mechanism controllin...

we use high-resolution electrical resistivity imaging to delineate the geometry of the landslide and discontinuity surface between slide mass and bedrock in roudbar region, ghazvin-rasht-anzali railway (the tunnel no. 2 at km. 108+825). the roudbar region characterized by high geological hazard and shows a complete panorama of mass movements. in this area, different landslide types predisposed ...

Hydrostatic pressure response of $\mathrm{LaAu}{\mathrm{Sb}}_{2}$ charge density wave (CDW) system is investigated using electrical transport, x-ray diffraction (XRD), and density-functional theory (DFT). Resistivity data at ambient evidence a clear CDW transition 83 K. X-ray reveals that in plane out axes show opposite behavior with decreasing temperature, particular, $c$ axis develops distinc...

We studied electrical resistivity and the Hall coe cient of single-crystalline samples of an oxide superconductor Sr2RuO4 under hydrostatic pressures up to 1.2 GPa. The value of Tc decreases by 36 % at 1.2 GPa, while no appreciable change in the resistivity or the Hall coe cient has been observed. At room temperature an unexpected increase of resistivity along the c axis occurs with increasing ...

The low-temperature electrical resistivity of corrugated semiconductor films is theoretically considered. Nanoscale corrugation enhances the electron-electron scattering contribution to the resistivity, resulting in a stepwise resistivity development with increasing corrugation amplitude. The enhanced electron scattering is attributed to the curvature-induced potential energy that affects the m...

This paper analyzes data taken by Gower-Hall for his MIT PhD thesis. In his thesis, Gower-Hall examines run-to-run control of epitaxial film deposition by way of thickness and resistivity measurements of the film deposited. Our main focus is analysis of the resistivity data captured from the experiments. We give an overview of the thesis, confirm Gower-Hall’s findings of the main factors influe...

The electrical resistivity of Co/Ni and Cu/Ni superlattices exhibit resistivity oscillations as a function of superlattice period L, while Ag/Pd does not. Moreover, the resistivity of Co/Ni superlattices shows quantum size effects and a resistivity enhancement with L, as a function of total film thickness d . These results are consistent with a model which assumes d-electron localization in the...

The influence of the addition of carbon on the crystalline structure and resistivity of polycrystalline silicon layers grown by simultaneous decomposition of SiH,, C^H. a n d P H T a t '°"° c w a s studied. Carbon content, morphology, preferred orientation, crystallite size, lattice strains and resistivity were determined. It was found that carbon has a pronounced effect on the crystalline stru...
