REE Accessory Minerals in the Gneiss and Granulite Clasts from the Silesian Unit (Western Outer Carpathians, SE Poland) as Indicators of Metamorphic Processes
Jan 01, 2006; ... Introduction REE accessory minerals play the important role in metamorphic petrology. Their significance is related to their hosting of trace elements in metamorphic rocks and, therefore, providing important information about evolution that these rocks experienced. Phosphates (especially ...
Geology and Tectonics of the Vrsatec Klippen Area (Pieniny Klippen Belt, Western Slovakia)
Jan 01, 2006; ... The Pieniny Klippen Belt (PKB) represents a tectonic zone separating the External (Outer) Western Carpathians from the Central (Inner) Western Carpathians. It is a narrow, independent structural belt with extraordinarily complicated structure, which stretches from the vicinity of Vienna, through ...
Tectonic Deformations in the Orava Basin Margins in the Western Carpathians, Based on the DEM Analysis and Geological Research
Jan 01, 2006; ... The tectonic structure is the main issue of the Orava Basin geology but the Quaternary deposits make difficult presentation of the depression architecture. For the recognition of the linear morphological features which could depict the basement dislocations of the Orava Basin the digital ...
Olistostroms as Indicator of the Geodynamic Process (Northern Carpathians)
Jan 01, 2006; ... Existence and transformation of the accretionary wedge in the southern in the Northern Carpathians are documented by occurrence of olistostroms. During the detail mapping and lithofacies investigations of deposits in a few main tectonic units of the Outer (Flysch) Carpathians the olistostroms ...
The Fault Tectonics of the Middle Skawa River Valley (Polish Flysch Carpathians)
Jan 01, 2006; ... Upper Cretaceous and Paleogene rocks of the Silesian and Magura Nappes build up the complex structure of the investigated area, which is stretching along the Skawa River valley between Sucha Beskidzka and Swinna Porçba (Ksiazkiewicz 1972,1974a,b, Golonka et al. 2005). Middle and Upper Godula ...
Are There Olistoliths on the Eperkés Hill? The Paleomagnetic Answer
Jan 01, 2006; ... Epekés Hill is a classic exposure of the Jurassic-Lower Cretaceous successions in the Transdanubian Range, Hungary. Although the exposures of the Hill have been thoroughly studied during the last 40 years, facies interpretation is still subject of debate. According to some (Fülöp 1964, Konda ...
Upper Mantle Mylonites: Evidence for Hydrated Mantle Wedge Beneath the Eastern Transylvanian Basin
Jan 01, 2006; ... The severe effect of water on the deformation of the upper mantle (i.e. olvines) has only been recently recognized (e.g, Jung and Karato 2001, Katayama et al. 2004). The activation of slip systems (010)[001] ('b'slip) and (100)[001] ('c'slip) rather than the (010)[100] slip system ('a'slip) in ...
Multicomponent Diffusion Modeling of Garnet: a Tool To Estimate Burial and Exhumation Rate of Metamorphic Complexes
Jan 01, 2006; ... The occurrence of high-pressure rocks, mainly preservation and formation of concentration gradient within garnet or at its contact with other minerals provide evidence for the geodynamic processes of subduction and exhumation of crustal material within orogenic belts. With combination of the ...
