The Upper cretaceous calciclastic submarine fan deposits in the Eastern Pontides, NE Turkey: facies architecture and controlling factors
(2013)
The Tonya Formation, which represents the uppermost part of the Mesozoic sequence in the Eastern Pontides, consists of calciturbidites in Trabzon and its surrounding region. Two stratigraphic sections of the unit were ...
Upper Campanian calciclastic turbidite sequences from the Hacimehmet area (eastern Pontides, NE Turkey): integrated biostratigraphy and microfacies analysis
(Polska Akad Nauk, Polish Acad Sciences, Univ Warsaw, Geology Dept, 2014)
The upper Campanian (Cretaceous) of the Hacimehmet area (south of the city of Trabzon; Eastern Pontides) is mainly composed of calciclastic turbidites. the basinal unit of the 119 m thick succession includes thin red pelagic ...
Sequential formation of natrolite-group zeolites in amygdules of basaltic lavas
(Mineralogical Assoc Canada, 2015)
Natrolite-group minerals were found in amygdules in Middle Eocene basaltic lavas in northern central Anatolia and have been evaluated in detail by petrographical, mineralogical, and chemical studies. A sequential formation ...
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 ...
Effect of characteristics of natural zeolites on their geopolymerization
(Elsevier, 2021)
The properties of clinoptilolite-based geopolymers are investigated with a focus on the parameters affecting the reactivity of clinoptilolite in a geopolymer binder. A complete characterization of raw materials was carried ...
The multidisciplinary approaches on facies developments and depositional systems of the Bahcecik travertines, Gumushane, NE-Turkey
(Scientific Technical Research Council Turkey, TÜBİTAK, 2021)
The Bahcecik travertines, located in Gumushane (NE-Turkey) have been investigated for the first time using a multidisciplinary approach, which included sedimentological (lithofacies, depositional system), petrographic, ...
Palaeobiogeographical implications of the first fossil wood flora from the Jurassic of Turkey
(Instytut Paleobiologii PAN, 2022)
We describe Jurassic fossilized woods from the Gümüşhane and Erzurum regions of Turkey that represent the eastern Sakarya Zone (eSZ) terrestrial biota. We collected 27 fossil wood fragments in total. All 27 fossil wood ...
Mechanical and radiation attenuation properties of conventional and heavy concrete with diverse aggregate and water/cement ratios
(Croatian Association of Civil Engineers, 2022)
This paper presents the results of comprehensive laboratory work conducted for investigating the mechanical and radiation attenuation characteristics of heavyweight concrete produced with pyrite, chromium, and magnetite ...
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 ...
Compressive strength and microstructural characteristics of natural zeolite-based geopolymer
(Budapest Univ Technology Economics, 2018)
A detailed study of geopolymeric reaction products and mechanical properties of geopolymer pastes prepared with natural zeolite has been investigated by means of compressive strength, XRD and SEM/EDX analysis. Sodium ...
