The Metamorphism And The Relationship Between Infra And Suprastructures Of The Bi̇tli̇s Massif – Turkey, Metin Şengün
The Metamorphism And The Relationship Between Infra And Suprastructures Of The Bi̇tli̇s Massif – Turkey, Metin Şengün
Bulletin of the Mineral Research and Exploration
The infrastructure of the massive consists essentially of amphibolites, gneisses and micaschists intruded by a biotite granite and the successive hololeucocratic phase. The mantling rocks of the suprastructure comprise metapelitic rocks unconformably underlying metacarbonates dated as Middle Devonian- Mesozoic. The infra-suprastructure boundary is interpreted as a surface of transgressive overlap. The rocks of infra and suprastructure are involved in isoclinal folds with ductile deformation along most of the boundary conclusively suggesting in situ position of the suprastructure during the Alpine deformation. The shear planes are discontinous, en echelon and run independently of the infra-suprastructure boundary. A uniform sequence of Palaeozoic …

Origin And Petrology Of Ekeci̇kdağ Granitoid In Western Central Anatolian Crystalline Massif, M. Cemal Göncüoğlu, Orhan Akiman
Bulletin of the Mineral Research and Exploration
A belt formed by a number of granitoid intrusions is situated at the western part of the Central Anatolian Crystalline Massif. One of the granitoid intrusion at the southwest of the belt crops out between Aksaray and Ortaköy and is called Ekecikdağ. Ekecikdağ granitoid, which is composed of monzogranites and granodiorites. intruded both the metamorphic and ophiolitic host rocks. Ekecikdağ granitoid is differentiated into following subunits with respect to their petrographical and chemical composition: Borucu granodiorite-monzogranite, Sinandi microgranite, Hisarkaya porphyribc granite, Kalebalta teucogranite and aplite granite. All these subunits are genetically related to each other. Borucu granodiorite-monzogranite represents the main …

Grain Size Analysis Of Some Olistostromes Between Balkuyumcu And Alci (Sw Ankara), Engin Olgun, Teoman Norman
Bulletin of the Mineral Research and Exploration
Sedimentary features and the detailed grain size analyses of six olistostromes (debris flows) have been examined; they are located between Alcı and Balkuyumcu villages, 40 km. southwest of Ankara. Photograph-grid method and sieving methods are used for gram size distribution analyses. The distribution of clast sizes within olistostromes are shown as histograms and cumulative curves. After calculating the main gram size parameters, their relations with respect to each other are examined on distribution diagrams (scatter diagrams). So, some of the distinguishing characteristics of olistostrome clast size distributions have been established. Studies on the clast size distribution and clast roundness indicate …

An Example To Sepiolite Formation In Volcanic Belts By Hydrothermal Alteration: Kibriscik (Bolu) Sepiolite Occurrence, Taner Irkeç, Taner Ünlü
Bulletin of the Mineral Research and Exploration
Geological, mineralogical and chemical properties of a sepiolite occurrence, located in the south of Kıbrıscık township of Bolu Province, north central Turkey, have been investigated in detail, and new mineralogical data have been obtained. Differing from the sedimentary sepiolite deposits, mostly associated with the carbonate/evaporite sequences, Kıbrıscık sepiolite occurs in the Köroğlu (Gallatian) Volcanic Belt and has formed by the hydrothermal alteration of the vitric tuff unit of Middle Miocene aged Deveören Volcanites. The mineral, which shows a similar XRD pattern to sepiolite, gives DTA and IR patterns with close resemblance to those of palygorskite, in addition to its chemical …

Presence Of Rudist Bearing Limestone Blocks Derived From The Arabian Platform In Gevaş (Van) Ophiolite, Sacit Özer
Bulletin of the Mineral Research and Exploration
The Gevaş ophiolite consists of ultramafic rocks, gabros, lavas, tuffs, cherts, shales, and it contains also limestone blocks. The majority of these limestone blocks are unfossiliferous. The fossiliferous limestones are observed only around İkizler and Dilmetaş villages. The sandy limestones cropping out near İkizler village have rare fossil such as rudists, gastropods, and some coral fragments. However, the limestone block of Dilmetaş village contain a rich macrofauna consisting of rudist, gastropods, lamellibranchs and corals. The rudist fauna consist of Dictyoptychus cf. euphratica, Dictyoptychus sp., Hatayia sp., Hippurites syriaca, Hippurites comucopiae, Vaccinites sp. and Sabinia sp. indicating a Maestrichtian age.
