Obsidian has been a center of interest both for geologists and archaeologists. Geologists have studied on physical and chemical properties of obsidian where archaeologists have worked on this material as a common artifact found in excavations. In this study, obsidian samples from Çatalhöyük excavations are examined using their rare earth element (REE) concentrations. Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) have been used for this purpose. A mixture (4:1) of lithium metaborate and lithium tetraborate was used for fusion of samples. Because of the low concentrations of REEs, a preconcentration step is needed. Successful recovery results have been achieved with Amberlite IR-120. The developed method is tested using the standard reference material SARM-1.

USE OF SEA-WATER IN THE FLOTATION OF CARBONATE RICH SEDIMENTARY PHOSPHATE ROCK
Özbelge, Hilmi Önder; ALFARISS, TF; ABDULRAZIK, AM (Springer Science and Business Media LLC, 1993-01-01)
There is an appreciable amount of carbonaceous sedimentary phosphate deposits in the northern Africa and the Middle East which are expected to gain importance in the near future because of the depletion of the deposits in Florida. In many of the regions where phosphate deposits are found there is a shortage of fresh water, and sea is not very far. The use of sea water instead of fresh water in flotation of carbonaceous phosphate rock is successfully demonstrated. Thus an appreciable reduction in the operati...
Development of a geotechnical and geophysical database for seismic zonation of the Ankara Basin, Turkey
Koçkar, Mustafa K.; Akgün, Haluk (Springer Science and Business Media LLC, 2008-07-01)
Engineering geological and geotechnical site characteristics were assessed and seismic hazard studies performed for the Upper Pliocene to Pleistocene fluvial and Quaternary alluvial and terrace deposits for a site west of Ankara, Turkey. Sediment conditions were determined and a soil profile was characterized by surface geophysical methods. These studies were integrated with existing in-situ characterization studies to create a seismic and geotechnical database for the site. A seismic zonation map of the si...
Effect of Weathering Tests on Microfracture Properties of the Massive and Vesicular Basalts
DURSUN, FELAT; Topal, Tamer (2020-10-03)
Petrographic investigations not only provide knowledge on the mineralogical state and provenance of rock materials, they also can be used as a strong tool for evaluating its weathering potential and durability. It is known that the type, amount, dimension, orientation and density of cracks have a great influence on the weathering of the stone material. The chemical agents, for instance, that cause weathering in rock materials, use cracks to penetrate their depths. This study aims to understand how accelerat...
Assessment of discrimination of mafic rocks using trace element systematics with machine learning
Öztürk, Mehmet Sinan; Sayıt, Kaan; Department of Geological Engineering (2019)
Having an important role in the elucidation of the evolution of ancient oceans and related continental fragments, the determination of original tectonic settings of ancient igneous rocks is an essential part of the geodynamic inferences. Geochemical classification of mafic rocks is important for the tectono-magmatic discrimination of igneous rocks especially when geological information is insufficient as the link of the igneous rocks to their original tectonic setting had been erased due to large scale even...
Tarihi mermerlerin korunmasında biyomineralleştirme ve nanotaneler teknolojilerini kullanarak yeni metotlar geliştirme
Saltık, N. Emine Caner(2007)
Anıtların ve arkeolojik alanların atmosferik koşullara açık olan taşları, çeşitli fiziksel, kimyasal ve biyolojik değişimlere uğramaktadırlar. Zaman içinde bu değişimler, taşın mikroyapısında yüzeyden içeriye doğru ilerleyen bozulmalara neden olmakta ve oluşan önemli değişiklikler, toplam gözenekliliğin artması, mekanik özelliklerin azalması, kimyasal bileşim değişimleri ve diğerleri olarak izlenmektedir. Tarihi taşlardaki bozulma değişimleri, görsel olarak da izlenmektedir. Bunlar, renk değişimleri, biriki...
