Geochemical evolution and petrogenesis of the eocene Kashmar granitoid rocks, NE Iran: implications for fractional crystallization and crustal contamination processes
Kashmar granitoids of Taknar zone, in north part of Lut block, intruded into volcanic rocks and consist of granites, granodiorites, monzodiorite and gabbrodiorites. They are composed of mainly plagioclase, alkali-feldspar, quartz, amphibole, biotite and pyroxene minerals. Harker diagram variation, including negative correlations CaO, MgO, FeO, TiO2 and V and positive correlations K2O, Rb, Ba, a...
متن کاملCrustal deformation study using SAR interferometry Crustal deformation measurements relating to earthquakes and volcanic activity are
We have examined the precision of interferometric SAR measurements of surface deformation of the Earth using 24-cm wavelength data acquired by the Japanese Earth Resources Satellite 1 (JERS 1) spacecraft, over the lzu peninsula, Japan. Radar images acquired from 1993 to 1994 were made into eleven independent interferograms. Apparent water vapor signatures with equivalent path delay up to 16 cm ...
متن کاملThe Crustal Structure of Orientale and Implications for Basin
Introduction. The topography [1] and gravity [2] of the Moon are dominated by the signatures of impact basins and the mascon gravity anomalies contained within. A method of generating higher resolution crustal thickness models by utilizing the symmetry of the basins is here presented, providing a refined view of the subsurface structure of the basins, with a focus on Orientale. The crustal stru...
متن کاملCrustal Deformation in Great California Earthquake Cycles
Periodic crustal deformation associated with repeated strike-slip earthquakes is computed for the following model; A depth L (< H) extending downward from the Earth's surface at a transform boundary between uniform elastic lithospheric plates of thickness H is locked between earthquakes. It slips an amount consistent with remote plate velocity Vp• after each lapse of earthquake cycle time Tcy. ...
متن کاملThe Crustal Structure
This thesis consists of three papers examining problems related to the crustal structure, isostasy and subsidence history of aseismic ridges and mid-plate island chains. Analysis of gravity and bathymetry data across the Ninetyeast and eastern Walvis Ridges indicates these features are locally compensated by an overthickening of the oceanic crust. Maximum crustal thicknesses are 15-30 km. The w...
