Geochronology of plutonic rocks from the Sanandaj-Sirjan zone,Iran and new zircon and titanite U-Th-Pb ages for granitoids from the Marivan pluton

The Sanandaj-Sirjan zone of Iran is a metamorphic belt consisting of rocks which were metamorphosed under different pressure and temperature conditions and intruded by various plutons ranging in composition from gabbro to granite. The majority of these granitoids formed along the ancient active continental margin of the Neo-Tethyan ocean at the southeastern edge of the central Iranian microplate. Geochronological data published in recent years indicate periodic plutonism lasting from Carboniferous through Mesozoic to late-Paleogene times (from ca. 300 to ca. 35 Ma) with climax activity during the mid- and late-Jurassic. The age constraints for plutonic complexes, such as Siah-Kouh, Kolah-Ghazi, Golpayegan (Muteh), Azna, Aligoodarz, Astaneh, Borujerd, Malayer (Samen), Alvand, Almogholagh, Ghorveh, Saqqez, Marivan, Naqadeh and Urumieh, clearly indicate the periodic nature of magmatism. Therefore, the Sanandaj-Sirjan zone preserves the record of magmatic activity of a complete orogenic cycle related to (1) Permocarboniferous(?) rifting of Gondwana and opening of the Neo-Tethyan ocean, (2) subduction of the oceanic crust, (3) continental collision and (4) post-collision/post-orogenic activities. The formation of the Marivan granitoids, northwestern Sanandaj-Sirjan zone, for which we present U-Pb zircon and titanite ages of ca. 38 Ma, can be related to the collisional and post-collisional stages of this orogenic cycle.     

Migration and the built environment: a spatial analysis of resettlement in Çeşme,Turkey

At the beginning of the twentieth century, the retreat of the Ottoman Empire caused a massive scale migration in the Aegean regions. This process was furthered by the Treaty of Lausanne (1923) between the Turkish Republic and Greece. Gradually, more than one million people were formally exchanged under the control of the respective national authorities. This study shows that the predictions made by political authorities regarding the expected adaptation and homogenization based on religious affiliations failed to materialize; instead, the process of migration generated its own unique and autonomous processes derived primarily from cultural aspects and social origins. This research examines the materialization of the migrants’ adaptation practices and the spatial transformations in the built environment at both urban and domestic level, in order to indentify spatial and related social conflicts that arose as a result of socio-cultural mixing through a case study of the Çe?me Peninsula, Turkey. The study concludes that the relationship between social space and the physical environment is intertwined, with spatial transformations based on residents’ home of origin, professions and economic prosperity positioned in a clearly defined hierarchy of meaning.
