The Dikili-Candarli Volcanics, Western Turkey: Magmatic Interactions as Recorded by Petrographic and Geochemical Features
(Tubitak Scientific & Technological Research Council Turkey, 2007) Karacik, Zekiye; Yilmaz, Yuecel; Pearce, Julian A.
Located in the northwestern part of the Aegean region, Dikili- Candarli volcanic suite contains products representative for the western Anatolian Miocene volcanism. They can be divided into two main groups: the Dikili and the Candarli groups. The Dikili group is Early - Middle Miocene in age and consists mainly of pyroclastic rocks, andesitic- dacitic lavas, lava breccia, lahar flows and associated sedimentary rocks. The lavas contain disequilibrium phenocrysts assemblages. The Candarli group consists of Upper Miocene - Pliocene lava and sediment associations. The volcanic rocks consist mainly of rhyolitic domes and basaltic trachyandesite- basaltic andesite lavas erupted along the NW - SE- and NE - SW- trending fault systems; the faults controlled the development of the Candarli depression. Major- and trace- element chemistry indicates that the lavas are dominantly high- K, calc- alkaline, intermediate to acidic in composition. Chemical and textural characteristics of the minerals reveal that mixing was a common process in the generation of this magma. In particular, petrography, textural evidence and crystal chemistry of the phenocrysts together with variations in rock compositions indicate that basaltic- basaltic andesitic magma intruded dacite magma and is partially hybridized with it. New petrographic and geochemical data of Dikili-Candarli volcanics are closely similar to those of the active continental margin volcanism which are interpreted as mantle- derived magmas contaminated by crustal materials.

Petrochemistry of the south Marmara granitoids northwest Anatolia Turkey
(Springer, 2008) Karacik, Zekiye; Yılmaz, Yücel; Pearce, Julian A.; Ece, O. Isik
Post-collision magmatic rocks are common in the southern portion of the Marmara region (Kapidag Karabiga Gonen Yenice Can areas) and also on the small islands (Marmara Avsa Pasalimani) in the Sea of Marmara. They are represented mainly by granitic plutons stocks and sills within Triassic basement rocks. The granitoids have ages between Late Cretaceous and Miocene but mainly belong to two groups: Eocene in the north and Miocene in the south. The Miocene granitoids have associated volcanic rocks
