Metapelites of the Do Chah complex (SE Shahrood) are composed of micaschist, garnet micaschist, chloritoid schist and garnet-bearing gneiss. In the highest degree of metamorphism, metapelites have been affected by partial melting, resulting as granitization. A significant part of these rocks, imposed by compressional tectonic regime and show typical evidence of plastic deformation and intensive...

Abstract. In the Late Devonian to earliest Mississippian, Svalbard was affected by a short-lived episode of deformation named Svalbardian Orogeny. This event resulted in intense folding and thrusting sedimentary successions. Deformation stopped prior deposition Carboniferous Permian strata Billefjorden Gipsdalen groups, which lie unconformably over folded strata. Later on, presumed structures w...

In segmented paleorift systems such as the Pripyat–Dnieper–Donetsk aulacogen, which penetrate deep into continent from side of paleoocean margin and most often close here, each segment represents an autonomous structure lithosphere. The presented article shows that tectonic position Pripyat western closing indicated aulacogen was due to a change in intensity syn-rift plate-tectonic processes ex...

Abstract We introduce a novel method for map registration and apply it to transformation of the river Ister from Strabo’s World current in Geodetic System. This leads surprising but convincing result that best coincides with nowadays Tauernbach-Isel-Drava-Danube course not Danube what is commonly assumed. Such supported by carefully designed mathematical measurements resolves all related contro...

To investigate the architecture of transpressional deformation and its long-term relationship to plate motion in southern California, we have studied the deformation pattern and structural geometry of orogeny within the San Andreas fault system. The San Bernardino Mountains have formed recently at the hub of several active structures that intersect the San Andreas fault east of Los Angeles. Thi...

Recent zircon-based geochronological investigations in the Adirondack Mountains, in the state of New York, demonstrate that 1155 ± 6 Ma massif anorthosite was emplaced during the post-contractional phase (1160–1140 Ma) of the ca. 1200–1140 Ma Shawinigan orogeny. Emplacement of many other anorthosite – mangerite – charnockite – granite (AMCG) suites also correlates with the waning stage of oroge...

*Correspondence: Federico Luebert, Nees-Institut für Biodiversität der Pflanzen, Universität Bonn, Meckenheimer Allee 170, 53115 Bonn, Germany e-mail: [email protected] Andean orogeny is considered as one of the most important events for the development of current plant diversity in South America. We compare available phylogenetic studies and divergence time estimates for plant lineages that...
