Abstract Knowledge of the tectonic history Pamir contributes to our understanding both evolution collisional orogenic belts as well factors controlling Central Asian aridification. It is, however, not easy decipher Mesozoic–Cenozoic tectonics due extensive Neogene deformation in an orogen that remains largely understudied. This study reports detrital apatite and zircon fission‐track (FT) ages f...
Dehnow tonalite in west of Mashhad, NE Iran, is one of the oldest pluton in Mashhad Granitoied Complexes. This pluton cut by four systematic fracture sets. Among them, two sets show right lateral strike separation. Set A consists of parallel right lateral strike slip faults with a minor reverse slip component and Set B includes right lateral strike slip faults with a small component of normal s...
Dioritic plutons and pinkish alkali-feldspar granitic dikes of Kalateh area (northwest of Khur city) intruded in Neoproterozoic basemental of Jandagh- Arousan complex. Field observations, petrography and geochemical studies indicate that these intrusive rocks have I-type nature and belong to medium-high K calc-alkaline granitiods and also have genetically relationship with each other. Their par...
Two global-scale mantle convection cells presently exist on Earth, centred on upwelling zones in the South Pacific Ocean and northeast Africa: one cell (Panthalassan) contains only oceanic plates, the other (Pangaean) contains all the continental plates. They have remained fixed relative to one another for s 400 Ma. A transverse (Rheic^Tethyian) subduction system splits the Pangaean cell. Poloi...
This paper presents structural evidence of extensional activity in Central Alborz during Mesozoic. The structural evidence of homogenous early stage stretching such as layer-parallel to oblique boudinage of Permian and Triassic rocks in various portions of the study area accompanied by extensional-fibrous fractures were followed with more advanced extensional features. These extensional structu...
Continental break-up is an ingredient of plate tectonics and the Wilson cycle. During evolution Tethyan Realm since Paleozoic, a series ribbon-like (micro-)continents are split from Gondwana drifted northwards to Eurasian continent. The initial opening Neo-Tethys Ocean follows typical continental marginal Cimmeria Gondwana, which generally considered be driven by subduction Paleo-Tethyan plate....
s 131 The Cimmerian and the Elysian: How Musical and Extra-Musical Models and Expressive Ethos Affect the Compositional Process Adam Brantley Hill, PhD (Composition), University of Tasmania, 2004 This exegesis is a document of my rediscovery of emotion and expression in my music. It is also a chronicle of my acknowledgement and incorporation into my methodology of my many influences. Moreover, ...
The Ab-Bid deposit, located in the Tabas-Posht e Badam metallogenic belt (TPMB) Central Iran, is largest Pb-Zn (±Cu) deposit Behadad-Kuhbanan mining district. Sulfide mineralization formed Middle Triassic carbonate rocks and contains galena sphalerite with minor pyrite, chalcopyrite, chalcocite, barite. Silicification dolomitization are main wall-rock alteration styles. Structural textural obse...
This article examines the inlaid artefacts with garnets decorated carved spirals, which originate from Kerch and date late stage of Great Migration Period. According to B. Arrhenius, gemstones occurring in Europe Hunnic Post-Hunnic Periods were products Mediterranean workshops, primarily Constantinople. stone-working technology requires specific skills; barbarians did not have this period q...
