- BildiriYalnız künye2017Gamma ray spectrometry method in detecting the low sulfidation type epithermal Au+Ag mineralization (Gümüshane, Ne Turkey)
Maden, N.; Akaryali, E.
The gamma ray spectrometry has been widely used in mineral exploration, geological mapping and environmental radiation monitoring.The Eastern Pontide orogenic belt, which constitutes an important part of the Alpine-Himalayan system, hosts various types of economic mineral deposits of massive sulfide, porphyry copper, skarn, and epithermal vein-type ore deposits. Potassium is generally the most useful pathfinder element for gold mineralization zones. High level K/eTh, K/eU and Efimov F-Parameter (KeU/eTh) anomalies showed the alteration zones transmitting hydrothermal ore solutions to the surface. As a result, the gamma ray spectrometry, which is fast and economics method, might be used for estimation of prospective Au ore zones associated with the K alteration.

Bayram, A.; Satilmiş, U.; Nas, S.S.; Kemer, B.
The aim of this study is to monitor the fluoride ion (F-), as well as chloride ion (Cl-), variation in the Eastern Black Sea Basin streams, and to evaluate drinking water quality of these streams, with reference to national and international directives and guidelines. The water samples (240) were semimonthly collected from three surface water resources, namely from the Degirmendere and Galyan streams in Trabzon Province, the biggest city on the Southeastern Black Sea Coast with a total population of 768 417, and the Harşit Stream in Gümüşhane and Giresun provinces. The monitoring results have revealed that the average F-concentration had varied between 0.154 and 0.200 mg/l in the Degirmendere Stream and between 0.156 and 0.163 mg/l in the Galyan Stream, respectively. However, the treated stream waters had lower F-concentrations, varying between 0.010 and 0.080 mg/l, than the untreated stream waters. In the Harşit Stream, the average F-concentrations were at relatively higher values, which ranged from 0.211 to 0.296 mg/l, in the uppermost stations, however showed a steadily decreasing trend throughout the lowermost stations and fell from 0.230 to 0.141 mg/l due to the hydropower dam reservoirs, namely Torul, Kürtün, and Akköy, operated in the watershed. The average Cl-concentrations have varied between 2.00 and 6.48 mg/l. On the one hand, the waters from the Degirmendere, Galyan, and Harşit streams are classified as high quality, considering the upper threshold values of 1.5 mg F-/l and 250 mg Cl-/l. On the other hand, these streams can be regarded as the fluoride-poor water resources.

Öztürk, S.
An evaluation based on Gutenberg-Richter b-value, fractal dimension Dc-value, completeness magnitude Mc-value, annual probability and recurrence time of earthquakes is carried out for Tunceli province of Turkey. Earthquake catalog covers the years between 21 September 1970 and 30 December 2016, and contains 5462 earthquakes with magnitude equal to and greater than 1.1. Magnitude completeness is estimated as 2.8 and b-value is found as b=0.98+/-0.01. This b-value is smaller than average value of b=1.0 given for Gutenberg-Richter relation. So, this low b-value may be an indicator of stress to build up over time at the beginning of 2017. Dc-value is obtained as 1.63+/-0.04 with 95% confidence limits. This high Dc-value indicates that seismicity in Tunceli and vicinity is more clustered at larger scales or in smaller areas. Annual probability of the earthquakes between 4.5 and 5.5 magnitude levels exhibits a value between 1 and 10. Recurrence time of the earthquakes has a value between 10 and 30 years for magnitude levels between 5.5 and 6.0, and a value between 30 and 100 years for magnitude levels between 6.0 and 6.5. Consequently, this part of Turkey may have an earthquake potential for the possibility of intense earthquake occurrences in the next future.

Beker, Y.; Sayıl, N.
Seismic response characteristics of structures can be estimated by spectral ratios of microtremors measured on structures and their foundation ground surface. The microtremor horizontal-to-vertical-spectral-ratio (HVSR) technique has received great attention from all over the world with its simplicity together with quick information about dynamic characteristics of ground and structures. The HVSR of microtremors gives a good estimation of natural building frequency. In this study, Nakamura (H/V) method and Floor Spectral Ratio Method (FSR) has been applied to microtremor records taken with three component broad band velocity seismometers in seven different locations inside the building (ground floor; east and west side for second, fourth and sixth floor) and one at outside with the aim of determining the dynamic characteristics of Faculty building of Engineering and Natural Science at Gumushane University, in NE Turkey. The average predominant frequency, period and amplification values for the Faculty building are calculated. The ratio of amplitude spectrum of the upper floors to amplitude spectrum of the ground floor for both of horizontal components (East-West, North-South) is determined using FSR Method. The vibration frequency and period is around 4.0 Hz and 0.332 s, respectively. Also, the damping ratio and vulnerability were calculated to the Faculty building.

İncele - BildiriAçık Erişim2017Scopus SJRQ3K-Ar dating for determining the age of mineralization as alteration product: A case study of antimony mineralization vein type in granitic rocks of Gümüşhane area, Turkey
Vural, A.
Is it feasible to use K-Ar dating method in determination of the age of mineralization by utilizing alteration minerals? The purpose of this study was to examine the utility of the K-Ar dating method to accurately determine the age of mineralization. In ideal circumstances, dating of alteration products, such as illite and serisite minerals, gives the age of alteration event, which is indirectly associated with mineralization. In the study site, referred to as Avliyana, antimony mineralization (Gümüşhane, Turkey), stibnite (antimony) mineralizations of hydrothermal vein type were observed in granitic young intrusive rocks and the host rocks. In the study area, alteration was observed in the form of a small amount of weak silicification, argillitization (sericitization and illitization), hematitization, limonitization close to the mineralization and of epidotization and chloritization far from the mineralization. In order to determine the limits of the age of antimony mineralizations of the area, the K-Ar method was used to date illite and serisite minerals, which are alteration products related to mineralization. Two samples containing sericite and illite were collected from Avliyana antimonite mineralization. The alteration origin of these minerals was confirmed by supporting petrographic, XRD and scanning electron microscope studies. These samples were analysed for K-Ar dating.

Coastline changes are increasing rapidly due to both natural and human effects. The expansion of touristic, industrial and culture fishing establishments through coastal areas has brought about uncontrolled and unplanned urbanization. In this study, the coastline in Karasu district of Turkey has been extracted by using Unmanned Aerial Vehicle (UAV) images. For this purpose; 7 cm ground sample distance (GSD) UAV images taken in 2013 by Gatewing-X100 by 40% side and 70% forward overlap was used as post images. Produced ortho images were used as the base map for extraction of the coastline. An object-oriented approach has been applied to capture the shoreline from these ortho images. In the presented study, the eCognition object-oriented fuzzy image processing software has been used. This commercial software has the ability to develop custom tools for image classification in addition to its standard object feature tools. Customized arithmetic features have been used to achieve more accurate shoreline segmentation results. Three main object classes have been created as sea, shoreline buffer and land to extract shoreline. The segmentation results were converted into dxf vector data format. The results were compared with manual digitizing of 55 blind readers. An algorithm has been developed by using Matlab to analyze the differences between object-oriented classification and manual digitizing results. Results were evaluated according to students' gender, age, spent time, used software and courses taken. The root mean square error (RMSE) was calculated as 7.15 m.

Sahin, Yasin; Ulutas, Guzin; Imamoglu, Mustafa Bilgehan
Protecting database integrity has become a matter of increasing importance nowadays as accessing information is getting easier. Therefore, database watermarking approach to protect the integrity become an active research area. Most of the existing relational database watermarking techniques embed a generated watermark in the database. Zero watermarking is employed in the proposed technique by storing the watermark generated from the database in another medium independent from the database. In order to make the method robust to column replacement attacks, cell values are split into overlapping pairs and column number is added to pairs. The histogram of pairs is used as the watermark because any change in either a cell value or column replacement would affect the histogram. Experimental results indicate robustness to column replacement attack as well as improved processing time compared to other works reported in the literature.
