Comparative petrogenetic investigation of composite kackar batholith granitoids in Eastern Pontide magmatic arc - Northern turkey
The Pontides are an east-west trending orogenic belt which is subdivided into west, middle and eastern sectors according to their different tectonostratigraphy. The Eastern Pontides are represented by west-east-trending ... -
Geochemical and Pb-Sr-Nd isotopic constraints indicating an enriched-mantle source for late Cretaceous to early Tertiary volcanism, Central Anatolia, Turkey
Alpaslan, M; Frei, R; Boztug, D; Kurt, MA; Temel, A (TAYLOR & FRANCIS INC, 2004)Bulk-rock major, trace, and REE geochemistry and Pb-Sr-Nd isotopic compositions identify mantle sources involved in the genesis of volcanic rocks of the Upper Cretaceous-Lower Tertiary Ulukisla Formation, Camard-Ulukisla ... -
Geodynamic implications of rapid denudation of the granitoids at about 50 and 20 Ma in the Eastern Pontides, Turkey: Apatite fission-track results
Boztug, D; Jonckheere, R; Enkelmann, E; Ratscbacher, L; Wagner, G (PERGAMON-ELSEVIER SCIENCE LTD, 2005)… -
K-Ar age and stable isotope geochemistry of A-type granitoids in the Divrigi-Sivas region, Turkey
Boztug, D; Harlavan, Y; Arehart, GB (PERGAMON-ELSEVIER SCIENCE LTD, 2005)… -
K-Ar age determination, whole-rock and oxygen isotope geochemistry of the post-collisional Bizmisen and Calti plutons, SW Erzincan, eastern Central Anatolia, Turkey
Onal, A; Boztug, D; Kurum, S; Harlavan, Y; Arehart, GB; Arslan, M (WILEY-BLACKWELL, 2005)Post-collisional granitoid plutons intrude obducted Neo-Tethyan ophiolitic rocks in central and eastern Central Anatolia. The Bizmisen and Calti plutons and the ophiolitic rocks that they intrude are overlain by fossiliferous ... -
Magmatic processes and mixing origin of andesite: Miocene Karamagara volcanics, central Anatolia, Turkey
Alpaslan, M; Ekici, T; Otlu, N; Boztug, D; Temel, A (WILEY-BLACKWELL, 2005)The Miocene Karamagara volcanics (KMV) crop out in the Saraykent region (Yozgat) of Central Anatolia. The KMV include four principal magmatic components based on their petrography and compositional features: basaltic ... -
Mineral deposits associated with the pre-, syn- and post-collisional granitoids of the Neo-Tethyan convergence system between the Eurasian and Anatolian plates in NE and Central Turkey
The Neotethyan convergence system between the Eurasian plate and Tauride-Anatolide platform in NE and Central Turkey possess well-preserved igneous rocks characterizing different stages of convergence. The convergence ... -
Origin of the ultrapotassic volcanics within, the Late Cretaceous to Early Tertiary Uluki la Basin, Central Anatolia, Turkey
Alpaslan, M; Frei, R; Kurt, MA; Temel, A; Boztug, D (PERGAMON-ELSEVIER SCIENCE LTD, 2004)… -
Slow Senonian and fast Palaeocene-Early Eocene uplift of the granitoids in the Central Eastern Pontides, Turkey: apatite fission-track results
Boztug, D; Jonckheere, R; Wagner, GA; Yegingil, Z (ELSEVIER SCIENCE BV, 2004)Dating and forward modelling of the fission-track data of apatite samples from the Dereli-Sebinkarahisar region, south of Giresun in the Eastern Turkish Pontides, provides quantitative data on the regional tectonics resulting ... -
Some textural and geochemical evidences on mixing and mingling in the genesis of Karamagara Volcanics, Saraykent-Yozgat, Central Anatolia, Turkey
Alpaslan, M; Otlu, N; Ekici, T; Temel, A; Boztug, D (PERGAMON-ELSEVIER SCIENCE LTD, 2002)… -
The syn-collisional Danaciobasi biotite leucogranite derived from the crustal thickening in central Anatolia (Kirikkale), Turkey
The Behrekdag composite batholith, which crops out as a huge N-S-trending plutonic body in central Anatolia, Turkey, consists of five mappable granitoid units of Late Cretaceous age. They are (1) the S-type, peraluminous ... -
Timing of neotectonic fracturing by fission track dating of obsidian in-filling faults in the Ikizdere-Rize area, NE Black Sea region, Turkey
Yegingil, Z; Boztug, D; Er, M; Oddone, M; Bigazzi, G (WILEY-BLACKWELL, 2002)There are several NE-SW- and NNW-SSE-trending sets of neotectonic faults that are infilled with obsidians in the Ikizdere-Rize district of the NE Black Sea region, Turkey. Using the fission-track technique, it is estimated ...
