Crustal evolution of NW Iran: Cadomian arcs, archean fragments and the cenozoic magmatic flare-up
(Oxford Univ Press, 2017)The Cadomian orogen of NW Iran includes a series of metamorphic rocks with zircon U-Pb ages between ca 562 and 505 Ma (Ediacaran to middle Cambrian). the Ediacaran-Cambrian basement is intruded by a series of Late Eocene-Late ... -
Deciphering the shoshonitic monzonites with I-type characteristic, the Sisdaĝi pluton, NE Turkey: Magmatic response to continental lithospheric thinning
(Elsevier, 2012)Large-scale late Mesozoic to early Cenozoic plutons in the Eastern Pontide orogenic belt mostly show calc-alkaline and I-type geochemical features. However, we identify the Sisda?i pluton that has shoshonitic affinity and ... -
Development and characterization of clinoptilolite-, mordenite-, and analcime-based geopolymers: A comparative study
(Elsevier, 2021)This study examines the development of geopolymers from clinoptilolite, mordenite, and anal-cime and compares the properties of the resulting green-binding materials. Sodium silicate and sodium hydroxide solutions were ... -
Early Cambrian S-type granites in the Sakarya Zone, NE Turkey: A record for transition from subduction to post-collisional extension deduced from U-Pb zircon age and Nd-Hf isotopes
(Elsevier, 2022)Cadomian realms have recently received much attention in the Alpine-Mediterranean orogenic belts, with discontinuous outcrops extending from the Alps to the Istanbul Zone, Menderes Massif, Taurides in Turkey and Iran as ... -
