“…This observation is supported by the İvriz detachment determined in this study and by the alkaline character of volcanism that developed simultaneously with the Ulukışla formation (e.g., Alpaslan et al, 2004Alpaslan et al, , 2006. The synsedimentary normal faults in the Upper Cretaceous-middle Eocene sequence are overprinted by thrust faults (Figure 10), indicating a postmiddle Eocene contraction.…”

Post-collisional polycyclic plutonism from the Zagros hinterland: the Shaivar Dagh plutonic complex, Alborz belt, Iran

-The petrological and geochronological study of the Cenozoic Shaivar Dagh composite intrusion in the Alborz Mountain belt (NW Iran) reveals important clues to decipher complex relations between magmatic and tectonic processes in the central sectors of the Tethyan (Alpine-Himalayan) orogenic belt. This pluton is formed by intrusion at different times of two main magmatic cycles. The older (Cycle 1) is formed by calc-alkaline silicic rocks, which range in composition from diorites to granodiorites and biotite granites, with abundant mafic microgranular enclaves. The younger cycle (Cycle 2) is formed by K-rich monzodiorite and monzonite of marked shoshonitic affinity. The latter form the larger volumes of the exposed plutonic rocks in the studied complex. Zircon geochronology (laser ablation ICP-MS analyses) gives a concordia age of 30.8 ± 2.1 Ma for the calc-alkaline rocks (Cycle 1) and a range from 23.3 ± 0.5 to 25.1 ± 0.9 Ma for the shoshonitic association (Cycle 2). Major and trace element relations strongly support distinct origins for each magmatic cycle. Rocks of Cycle 1 have all the characteristic features of active continental margins. Shoshonitic rocks (Cycle 2) define two continuous fractionation trends: one departing from a K-rich basaltic composition and the other from an intermediate, K-rich composition. A metasomatized-mantle origin for the two shoshonitic series of Cycle 2 is proposed on the basis of comparisons with experimental data. The origin of the calc-alkaline series is more controversial but it can be attributed to processes in the suprasubduction mantle wedge related to the incorporation of subducted mélanges in the form of silicic cold plumes. A time sequence can be established for the processes responsible of the generation of the two magmatic cycles: first a calc-alkaline cycle typical of active continental margins, and second a K-rich cycle formed by monzonites and monzodiorites. This sequence precludes the younger potassic magmas as precursors of the older calc-alkaline series. By contrast, the older calc-alkaline magmas may represent the metasomatic agents that modified the mantle wedge during the last stages of subduction and cooked a fertile mantle region for late potassic magmatism after continental collision.

“…The Upper Cretaceous-Tertiary Ulukl la-Çamardl Basin is located on the south-western flank of the Central Anatolia Complex. The Ulukl la-Çamardl Basin has been interpreted such as a forearc basin (Görür et al, 1998), back-arc basin (Demirta ll et al, 1984), island-arc related basin (Oktay, 1982;Ba et al, 1986;ler, 1988), and rifting-related basin (Clark and Robertson, 2002;Alpaslan et al, 2004Alpaslan et al, , 2006.…”

In general, the papers published on the rocks of Ulukl la Basin mainly deal with stratigraphy, sedimentology, volcanic rocks, and general models for basin evolution.…”

The upper Cretaceous-Eocene Çamardl Formation is exposed along the northern edge of the Ulukl la Basin (central Anatolia) and consists of turbiditic sediments. The sediment geochemistry has been studied in order to understand the provenance, source area weathering, and tectonic setting of the basin. Çamardl Formation sediments are characterized by low to moderate SiO 2 contents, variable abundances of major elements, and a relatively high proportion of ferromagnesian elements. Evidence from discrimination diagrams of sedimentary provenance, tectonic setting, major element geochemistry and Sc/Th, Cr/Th, Co/Th, Zr/ Sc, La/Sc, La/Co, Cr/Sc, Y/Ni, and K/Rb values show that the Çamardl Formation sediments were derived from mafic, felsic, and intermediate sources. The chemical index of alteration (CIA: 57.63-78.11) revealed moderately weathered source rocks. Then major and trace element concentrations indicated deposition in an active continental margin and continental island arc settings.
