Bulletin of the Mineral Research and Exploration

The large fossil vertebrates obtained from the alluvial flood-plain deposits of the Kolankaya formation are determined as Skoufotragus laticeps (Andree, 1926) and Hipparion brachypus (Hensel, 1862), as representative elements of palaeomammal faunas spanning from the eastern Mediterranean to Iranian domains during the late Miocene (early-middle Turolian, MN11-12). These first Turolian records from the basin fill succession bear importance on reconstruction for the palaeobiogeographic diversity of relevant taxons as well as admit of interbasinal stratigraphic correlation for the Western Anatolian terrestrial Neogene basins.

Bulletin of the Mineral Research and Exploration

In Northwest Anatolia, widespread magmatism developed due to collision between Anatolide-Tauride platform and Sakarya continent during Late Cretaceous-Early Tertiary period. The granitoids in Biga Peninsula are products of post-collisional magmatism following the convergence of the northern branch of Neotethyan Ocean and developed in two different stages as Eocene and Oligo-Miocene. Eocene Karabiga, Güreci, Kuşçayır and Dikmen granitoids are granite and diorite-granodiorite; Oligo-Miocene Sarıoluk, Yenice, Kestanbol, Eybek, Evciler, Çamyayla and Alanköy granitoids are diorite, granodiorite, monzonite and Q-monzonite in composition. Metaluminous and peraluminous granitoids have similar geochemical variations and exhibit post-collisional geochemical signatures. Trace element patterns are almost similar to those …

Geochemistry And Tectonic Signifi Cance Of The Ophiolitic Rocks Of The Yarpuz-Kaypak (Amanoslar, Osmaniye) Area, Tamer Rizaoğlu, Utku Bağci, Osman Parlak

Bulletin of the Mineral Research and Exploration

Yarpuz-Kaypak (Osmaniye) region, located in Amanos Mountains, contains harzburgitic tectonites and mafic cumulates. The tectonites are represented by serpantinized harzburgites, whereas the cumulates are characterized by gabbronorite and gabbro compositions. The crystallization order within the cumulates is clinopyroxene, orthopyroxene plagioclase and amphibole. The major element compositions of the tectonites and cumulate rocks are consistent with formation in an arc-related tectonic setting. Trace element concentrations of these rocks exhibit large ion litophile element enrichments. Both geochemical and petrographic evidence suggest that the tectonite and cumulate rocks from the Yarpuz-Kaypak (Osmaniye) region represent the remnants of an oceanic lithosphere that formed in …

Bulletin of the Mineral Research and Exploration

In this study, the genus Alveolina D’ Orbigny, 1826 and its Alveolina (Alveolina) D’ Orbigny, 1826 and Alveolina (Glomalveolina) Hottinger, 1960 subgenera were re-examined and identified. Systematics of the subgenera Alveolina (Alveolina)=Alv. (Alv.) and Alveolina (Glomalveolina)=Alv.(Glomalv.) have also been reviewed and revised. Alv. (Glomalv.) is considered as a subgenus, not a genus (?). Because, all the generic features of microspheric generations (fB) of these two subgenera are identical. Thus, Alveolina D’ Orbigny, 1826 and Glomalveolina Hottinger, 1960 cannot be used as if they were two different genera (?). Otherwise Glomalveolina would be the synonym of Alveolina in “Systematic Paleontology” chapter. …

A Brief Note On The Effects Of Floating Standard Deviation (Non- Derivative) And Horizontal Gradient (Derivative) Filters, Ceyhan Ertan Toker Aug 2019

A Brief Note On The Effects Of Floating Standard Deviation (Non- Derivative) And Horizontal Gradient (Derivative) Filters, Ceyhan Ertan Toker

Bulletin of the Mineral Research and Exploration

When processing gravity data, the filters are used in space and frequency environments. The filters allow more selectable parameter estimations than raw data about the structure being examined. Filtering in a broad sense means monitoring the data under the constraints we want. While the filters allow some information to become more noticeable, they allow some information to be lost or become less noticeable from data. In this case, the losses in the data make the interpretation difficult and can cause errors. Derivative and phase filters provide quantitative information about the variation of data in different directions. The display of the …

Bulletin of the Mineral Research and Exploration

Each mineralization style is characterized by typical signature associations between elements due to elemental interactions, therefore the coherence and closure effects problem must be overcome in geochemical processing. The coherence indicates the ratios between two components (rows or columns) remains the same whether they are considered in a subcomposition or in the full composition. The log-ratio transformation (LRT) has recognized as a standard procedure to support subcompositional coherence. The log-transformed data is applicable for geochemical data to unveil such associations, prior to applying the multivariate analysis like correspondence analysis (CA) and principal component analysis (PCA). At the present study, subcompositional …
