Formation of the Egrikar (Gumushane) Fe-Cu skarn type mineralization in NE Turkey: U-Pb zircon age, lithogeochemistry, mineral chemistry, fluid inclusion, and O-H-C-S isotopic compositions
(Elsevier Science Bv, 2017)
The Egrikar Fe-Cu skarn type mineralization is located approximately 100 km NW of Gumuhane in NE Turkey. Geochemical analyses of diorite, which is thought to cause skarn, indicate medium K calc-alkaline (1.3 to similar to ...
Zigana Dağı (Gümüşhane, KD Türkiye) Dayklarının Jeokimyası ve Jeolojik Anlamı
(2019)
Eski bir magmatik yay olan Doğu Karadeniz Bölgesi (Pontidler) Sakarya Zonu içinde yer alan andezit ve porfirik dasit daykları Geç Kretase yaşlı volkanitleri kesmektedir. Andezit ve porfirik dasit daykları porfirik doku ...
The Sr, Nd, Pb and Hf isotopes and crystallization conditions of the middle Eocene Dadibi Pluton in the eastern Sakarya Zone, Turkey
(Cambridge University Press, 2023)
Magmatic activity in the Sakarya Zone, an important segment of the Alpine orogenic belt, continues intermittently from the middle Carboniferous to Miocene. In this study, we provide geochronological and geochemical data ...
Nature of clays in Late Cretaceous dacitic rocks in the eastern Sakarya Zone (NE Turkey): a geochemical and isotopic approach
(Scientific Technical Research Council Turkey-Tubitak, 2020)
Late Cretaceous felsic rocks are common in the eastern Pontides (NE Turkey). These rocks developed as an island arc from the Jurassic to the Miocene; they also host numerous volcanogenic massive sulfide deposits. The Late ...
Geochemical and Sr-Nd isotopic characteristics of Murgul (Artvin) volcanic rocks in the Eastern Black Sea Region (Northeast Turkey)
(Elsevier Gmbh, 2014)
The studied volcanic rocks are footwall and hanging wall dacites from the Murgul mine and the surrounding area. Moreover, the hanging wall dacites contain enclaves. Footwall dacite contains biotite, whereas hanging wall ...
LA-ICP MS zircon dating, whole-rock and Sr-Nd-Pb-O isotope geochemistry of the Camibogazi pluton, Eastern Pontides, NE Turkey: Implications for lithospheric mantle and lower crustal sources in arc-related I-type magmatism
(Elsevier, 2014)
Late Cretaceous I-type plutons are widespread in the Eastern Pontides, NE Turkey. The studied Camibogazi pluton is a composite pluton consisting of diorite, tonalite, monzodiorite, monzonite, quartz monzonite, granite, and ...
Eocene I-type magmatism in the Eastern Pontides, NE Turkey: insights into magma genesis and magma-tectonic evolution from whole-rock geochemistry, geochronology and isotope systematics
(Taylor & Francis Inc, 2020)
The Eastern Pontides orogenic belt in NE Turkey hosts numerous I-type plutons of Eocene epoch. Here, we report new U-Pb SHRIMP zircon ages and in situ zircon Lu-Hf isotopes along with bulk-rock geochemical and Sr-Nd-Pb-O ...
Organic geochemistry and element distribution in coals formed in Eocene lagoon facies from the Eastern Black Sea Region, NE Turkey
(2016)
The amount and type, the inorganic element content, and the maturity of organic materials of Eocene coals, shaly coals, and coaly shales exposed in the Gümüşhane and Bayburt districts of the Eastern Black Sea ...
Zigana (Gümüşhane, KD-Türkiye)volkanitlerinin alterasyon mineralojisi ve kütle değişimi
(2010)
Doğu Karadeniz (KD-Türkiye) metalojenik provensi’nde bulunan Zigana Dağı (Gümüşhane) civarındaki Geç Kretase volkanik kayaçları yoğun hidrotermal alterasyona ve çok az yüzeysel ayrışmaya maruz kalmışlardır. Tabanda bulunan ...
Bayburt kuzeyindeki (Doğu Pontidler, Türkiye) Senozoyik yaşlı plütonik kayaçların petrografisi, mineral kimyası ve kristallenme koşulları
(2018)
Doğu Pontidler, Paleozoyik’ten Senozoyik’e kadar farklı yaş aralığı, bileşim ve büyüklüğe sahip pek çok plütona ev sahipliği yapmaktadır. Bu plütonik kütlelerden özellikle Senozoyik yaşlı olanlar, Doğu Pontidler’in güney ...
