COAL-QUALITY PROPERTIES AND ENVIRONMENTAL INFLUENCES OF TERTIARY COALS OF THE ZILE (TOKAT) REGION IN CENTRAL ANATOLIA, TURKEY
Erik, Nazan Yalcin (VSB-TECH UNIV OSTRAVA, 2010)This study has done related to the coal-quality and the environmental influences of the Zile coal field which developed in a limnotelmatic deposition environment in the west of the Tokat. Around Zile, two coal seams with ... -
DEPOSITIONAL ENVIRONMENT CHARACTERISTICS OF UPPER CRETACEOUS SEDIMENTS IN HEKIMHAN BASIN (EASTERN ANATOLIA REGION, TURKEY): A BIOMARKER AND CARBON ISOTOPE APPROACH
Erik, Nazan Yalcin (GEOBALCANICA SOC, 2018)Biomarker analysis of soluble organic matter in the sediments such as shale has contributed to our understanding of the characteristics of the depositional environment. In this study, depositional environment properties ... -
Different types of learning algorithms of artificial neural network (ANN) models for prediction of gross calorific value (GCV) of coals
Yilmaz, Isik; Erik, Nazan Yalcin; Kaynar, Oguz (ACADEMIC JOURNALS, 2010)Correlations are very significant from earliest days, in some cases, it is essential as it is difficult to measure the amount directly, and in other cases, it is desirable to ascertain the results with other tests through ... -
Geophysical investigation and hydrocarbon potential of Cankiri-Corum Basin, Turkey
Aslan, Yasemin; Buyuksarac, Aydin; Erik, Nazan Yalcin; Aydemir, Attila; Ates, Abdullah (ELSEVIER SCIENCE BV, 2013)The Cankiri-Corum Basin is one of the larger, onshore sedimentary basins in central Turkey. In this paper, the integration of geophysical data and geological findings in the Cankiri-Corum Basin was performed and they both ... -
GROUND PENETRATING RADAR (GPR) METHOD OF GEOLOGICAL PROPERTIES OF COAL SEAMS NEAR THE SURFACE
Kosaroglu, Sinan; Erik, Nazan Yalcin (STEF92 TECHNOLOGY LTD, 2014)Requirement needed to energy increases as a result of the changes occured in today's technologic situations. The low-rank coals of Turkey represent the country's major energy source with their relatively large geological ... -
Hydrocarbon generation potential and Miocene-Pliocene paleoenvironments of the Kangal Basin (Central Anatolia, Turkey)
Erik, Nazan Yalcin (PERGAMON-ELSEVIER SCIENCE LTD, 2011)This study deals with the organic geochemical characteristics, hydrocarbon generative potential and Miocene-Pliocene paleoenvironments of the Kangal coal district, which developed in a limnic depositional environment and ... -
Hydrocarbon generation potential of late cretaceous shales and carbonates in Hekimhan basin and genetic relationships with Karadere oil seep (Eastern Anatolia Region, Turkey)
Erik, Nazan Yalcin (SPRINGER HEIDELBERG, 2018)In this study, Karadere oil seep (solid bitumen) and Late Cretaceous shales and carbonate levels of the Hekimhan Formation in Hekimhan Basin are compared genetically by means of organic-geochemical data. Investigated shale ... -
Investigation of the organic matter properties and hydrocarbon potential of the Sivas Basin, Central Eastern Anatolia, Turkey, using Rock-Eval data and organic petrography
Erik, Nazan Yalcin; Aydemir, Attila; Buyuksarac, Aydin (ELSEVIER SCIENCE BV, 2015)The main goal of this study is to assess the organic geochemical properties and hydrocarbon generation potential of the Tertiary units in the Sivas Basin which is one of the largest sedimentary basins in the Central Anatolia, ... -
On the Use of Conventional and Soft Computing Models for Prediction of Gross Calorific Value (GCV) of Coal
Erik, Nazan Yalcin; Yilmaz, Isik (TAYLOR & FRANCIS INC, 2011)Gross calorific value (GCV) is an important characteristic of coal and organic shale; the determination of GCV, however, is difficult, time-consuming, and expensive and is also a destructive analysis. In this article, the ... -
ORGANIC FACIES VARIATION FROM WELL DATA ON THE COALY PLIOCENE UNITS, THE CENTRAL PART OF TURKEY (KARAPINAR-KONYA)
