Molluscan Assemblage And Paleoecology Of Lower Miocene Sequences Of The Munzur Mountains (Eastern Anatolia, Turkey), Müjde Gürsoy Dec 2017

Molluscan Assemblage And Paleoecology Of Lower Miocene Sequences Of The Munzur Mountains (Eastern Anatolia, Turkey), Müjde Gürsoy

Bulletin of the Mineral Research and Exploration

The research subject is the Miocene aged units that located in the Munzur Mountains at the Ovacik district of Tunceli province. There is a continued sediment deposits from Paleozoic to Cenozoic at the Munzur Mountains. The neritic limestones of the Miocene Başpınar Formation outcropping in the Ovacık district are rich in fossil groups of gastropods and bivalves. In this study, 336 samples from the Başpınar Formation have been evaluated. Seven species of Gastropoda (Globularia carlei, Granulolabium plicatum, Granulolabium (Tiaracerithium) thiarella, Tympanotonus margaritaceus, Terebralia subcorrugata, Nassarius erunalae, Cerithium vulgatum,) and four species of Bivalvia (Cardita rusticana, Anadara aquitanica, Cubitostrea digitalina, Ostrea …

Bulletin of the Mineral Research and Exploration

The aim of this study is to determine the hydrologic characteristics and to analyze the temporal saturation degree variations of Demirciköy Watershed which is located in Sinop City and subjected to rapidly increasing population. This study is important in terms of preventing the natural disasters such as flood, storm water, landslide and mitigation of damages within the frame of watershed planning concept. This study consists of field, office and laboratory stages. In context of field studies, representative soil samples are taken from study area. Within the scope of laboratory studies, soil hydrologic properties are characterized with the determination of soil …


Geology And Geochemistry Of Nodular-Phosphate And Fault-Controlled Hydrothermal-Phosphate Mineralizations In Arikli And Nusratli Villages (Ayvacik-Çanakkale, Nw Turkey), Abdulbaki̇ Günaydin Dec 2017

Geology And Geochemistry Of Nodular-Phosphate And Fault-Controlled Hydrothermal-Phosphate Mineralizations In Arikli And Nusratli Villages (Ayvacik-Çanakkale, Nw Turkey), Abdulbaki̇ Günaydin

Bulletin of the Mineral Research and Exploration

Uranium bearing phosphate mineralizations in the tuffs (ignimbrites) of Middle Miocene Arıklı volcanites in the vicinity of Arıklı and Nusratlı villages, Çanakkale have been known since 1977. In the study area, two types of phosphate mineralizations are present in different parts. First type and important one is in the tectonic zones in tuffs and along the contact between tuffs and Çetmi ophiolite and along the contacts of the units of the Küçükkuyu Formation in the Muharremin Tepe, Feyzullah Tepe, Örencik Tepe, Gedikharman Tepe in north and northwest of Arıklı village. Second type is the vein type mineralizations in the tuffs …


Alteration Zones Associated With Eocene Magmatism In The Olur (Erzurum) Area, Eastern Pontides And Their Significance, Güzide Önal, Mustafa Akyildiz, İsmet Cengi̇z, Mehmet Aslan, Serkan Özkümüş Dec 2017

Alteration Zones Associated With Eocene Magmatism In The Olur (Erzurum) Area, Eastern Pontides And Their Significance, Güzide Önal, Mustafa Akyildiz, İsmet Cengi̇z, Mehmet Aslan, Serkan Özkümüş

Bulletin of the Mineral Research and Exploration

The Alpine Orogenic Belt with numerous porphyry Cu-Mo-Au mineralizations, starts from Eastern Europe continues through Turkey and the Caucasus and extends into Iran and Afghanistan. The study area of the Eastern Pontides is in this orogenic belt. Using fi eld and laboratory studies an attempt has been made to establish the origin of Yeşilbağlar, Kaban and Köprübaşı alteration zones in the Olur area (Erzurum). In the study area Early Eocene Coşkunlar volcanics and sub volcanic rocks have contact with the Oltu çayı volcanics of Early-Middle Jurassic. Alteration in the study area effects these Oltuçayı and Kaban volcanics. In the study …

An Approach To Coast Edge Line At The Eastern Antalya Marginal-Marine Sea Sides, Muhittin Görmüş, Levent Başayi̇ği̇t, Ahmet Uysal

Bulletin of the Mineral Research and Exploration

In this study, geological and geomorphological studies having the solution approaches for the coast edge line problem at the marginal-marine environments were realised and some solutions were proposed. The eight following locations were chosen: South of Lara Main Road (1), Aksu River Exit (2), Acısu Stream-2 (3), Ağılısu Stream Exit (4), Köprüçay Exit (5), seashore at the south of Evrenseki (6), seashore at the east of Side (7) and Kızılot (8). Past and new images of the Google Earth satellite views, topographic maps and aerial views; lithological-sedimentological observations, fauna data in sediments, plant cover, artificial structures, previous literature and related …


Permeability Of Savcibey Dam (Bi̇leci̇k) Axis Location And Design Of Grout Curtain, Mustafa Can Canoğlu, Bedri Kurtuluş Apr 2017

Permeability Of Savcibey Dam (Bi̇leci̇k) Axis Location And Design Of Grout Curtain, Mustafa Can Canoğlu, Bedri Kurtuluş

Bulletin of the Mineral Research and Exploration

This study comprise the design of the planned grout curtain in Savcıbey Dam (Söğüt/Bilecik) in order to provide impermeability along the dam axis. Within the context of field studies, engineering geology map was generated, ground investigation drilling was realized and permeability tests were performed. Within the field studies, the joint conditions of the geological units (Triassic aged Bozüyük Metamorphic schists) under the dam axis and its effect on permeability was observed considering the positions of the discontinuities with regard to the dam axis location. Orientation of discontinuities generally have strikes changing between N – S and NNE – SSW. 5 …


Investigation Of Güllük (Muğla) Wetland By Stable Isotopes (Δ18o, Δd), Melis A. Somay Apr 2017

Investigation Of Güllük (Muğla) Wetland By Stable Isotopes (Δ18o, Δd), Melis A. Somay

Bulletin of the Mineral Research and Exploration

Wetlands play an important role in the hydrologic cycle. This investigation was completed to determine the origin of waters and recharge-discharge areas using stable isotopes (δ18O and δD) which are fingerprints of the water in Güllük (Muğla) wetland. This area is important both economically and in terms of aquaculture environment in Turkey. Sample locations were selected from not only wetlands but also the possible recharge area that consists of karstic springs and streams. EC (Electrical Conductivity) of the waters range between 5080-41000 µS/cm, except streams. δ18O and δD contents of the samples ranged from -6.00‰ to 0.50‰ and from -29.1‰ …

Bulletin of the Mineral Research and Exploration

This paper explain research results for Holocene sedimentary processes and controlling factors on Datça and Hisarönü Bays located in south west Turkey. For this purpose, we collected sea bottom grab samples (upper 30 cm) from 71 stations and seismic profiles (we use only one sample explain to sedimentary process) collected in MTA-SELEN research ship on Hisarönü and Datça Bays. It is known and widely applied in seismic analysis methods and techniques are used on seismic profile which according to the continental shelf edge or threshold current -90 / -120 m water depth. At the same time, seismic profile were showed …
