Crustal 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 کاملInvestigation of the role of fractional crystallization, crustal assimilation and magma mixing in turquoise hosted sub-volcanic intrusion rocks in south of Damghan mine, Iran.
Granodiorite and dioritic intrusive rocks (Middle Eocene age) intruded the Lower-Middle Eocene volcanic rocks at the northern parts of the Torud-Chah Shirin volcano-plutonic belt in north east of Iran. This granodiorite is intruded by small rhyolitic dome in the Damghan turquoise-gold mine. According to all data, these intrusive rocks are related to a common source. The primary magma evolved by...
متن کاملPetrogenesis of volcanic rocks from Razei region in Northwest Ardabil, Iran
The Razei region in the northwest of Ardabil is considered a part of West Alborz-Azerbaijan. Rocks in this area were created by Eocene volcanic activities. These rocks range from andesite to olivine basalt. The common texture of these rocks is Porphyritic with microlithic matrix. The phenocrysts of these rocks are often clinopyroxene, plagioclase, and olivine. The texture is made of microlithic...
متن کاملThe enigma of crustal zircons in upper-mantle rocks: Clues from the Tumut ophiolite, southeast Australia
We suggest a new explanation for the presence of crustally derived zircons in the upper-mantle rocks of ophiolitic complexes, as an alternative to subduction-related models. Integrated isotopic (U-Pb, Hf, and O isotopes) and trace-element data for zircons from the Tumut ophiolitic complex (southeast Australia) indicate that these grains are related to granitic magmatism and were introduced into...
متن کاملthe crustal structure beneath the northwest of the zagros (kermanshah region) from teleseismic receiver functions
in this study, we used teleseismic data which was recorded by 5 stations (dhr, ghg, kom, lin and vis) of the kermanshah seismic network from 2003 to 2007 with mb?5.5 and epicentral distances from 30° to 95°. the crustal structure beneath these stations was determined by the modeling of the p receiver functions. the main phases, which were observed in our final p receiver functions, are moho con...
