Late Cretaceous Arc Igneous Activity: The Eğrikar Monzogranite Example
(International Geology Review, 2018)
The geochemical and Sr–Nd–Pb isotope properties, as well as the Laser Ablation Inductively Coupled Plasma and Mass Spectrometry (LA-ICP-MS) U–Pb zircon age, of Eğrikar Monzogranite in the eastern Pontides, are primarily ...
Formation of skarns at Gümüşhane (Northeastern Turkey)
(Neues Jahrbuch für Mineralogie-Abhandlungen, 2011)
Skarn deposits are located in the NE Black Sea region of Turkey belonging to the Alpin metallogenic province. The Fe skarn deposit at Arnastal is hosted by Late Cretaceous carbonate rocks comprised of limestone and the ...
The Geochemical and Sr-Nd isotopic Characteristics of Murgul (Artvin) Volcanics in the Eastern Black Sea Region (NE Turkey).
(Chemie der Erde/Geochemistry, 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 ...
K-Ar dating, whole-rock and Sr-Nd isotope geochemistry of calc-alkaline volcanic rocks around the Gümüşhane area: implications for post-collisional volcanism in the Eastern Pontides, Northeast Turkey
(Springer-Verlag Wien, 2013-05-14)
Volcanic rocks from the Gümüşhane area in the southern part of the Eastern Pontides (NE Turkey) consist mainly of andesitic lava flows associated with tuffs, and rare basaltic dykes. The K-Ar whole-rock dating of these ...
LA-ICP MS zircon dating, whole-rock and Sr–Nd–Pb–O isotope geochemistry of the Camiboğazı pluton, Eastern Pontides, NE Turkey: Implications for lithospheric mantle and lower crustal sources in arc-related I-type magmatism
(Elsevier B.V. All rights reserved, 2014-02-15)
Late Cretaceous I-type plutons arewidespread in the Eastern Pontides,NE Turkey. The studied Camiboğazı pluton is a composite pluton consisting of diorite, tonalite, monzodiorite, monzonite, quartz monzonite, granite, and ...
Mineralogy, whole-rock and Sr–Nd isotope geochemistry of mafic microgranular enclaves in Cretaceous Dagbasi granitoids, Eastern Pontides, NE Turkey: Evidence of magma mixing, mingling and chemical equilibration
(0009-2819/$ - see front matter r 2008 Elsevier GmbH. All rights reserved. doi:10.1016/j.chemer.2008.08.002, 2008-08-04)
Rocks of the Late Cretaceous Dagbasi Pluton (88–83 Ma), located in the eastern Pontides, include mafic microgranular enclaves (MMEs) ranging from a few centimetres to metres in size, and from ellipsoidal to ovoid inshape. ...
Organic geochemical characteristics and depositional environments of Eocene deposits in the Eastern Black Sea Region, NE Turkey
(Energy Sources, Part A, 2013)
The type of organic material, thermal maturity, depositional environment, and source rock potential of Eocene-aged clastic rocks of the Eastern Black Sea Region were investigated. Based on total organic carbon (TOC) values, ...
Organic maturity and hydrocarbon potential of Liassic coals from the eastern Pontides, NE-Turkey
(Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2011-07-08)
Organic matter content, type of organic material and thermal maturity of Lias-aged coals of the Gumushane and Bayburt areas were investigated. The total organic carbon (TOC) contents of coals in the Gumushane area range ...
Petrogenesis of the late Cretaceous Turnagöl intrusion in the eastern Pontides: Implications for magma genesis in the arc setting
(Production and hosting by Elsevier, 2012-09-28)
A series of Cretaceous plutons is present in the eastern Pontides of northeastern Turkey. The Turnagöl intrusion is the least studied and, thus, the least understood plutons in the orogen. This intrusion consists of ...
Petrochemistry and petrology of I-type granitoids in an arc setting: the composite Torul pluton, Eastern Pontides, NE Turkey
(Springer-Verlag 2007, 2007-04-16)
The Upper Cretaceous Torul pluton, located in the Eastern Pontides, is of sub-alkaline affinity and displays features typical of volcanic arc granitoids. It is a composite pluton consisting of granodiorite, biotite hornblende ...
