“…Actively mined chromitite occurences within the mantle tectonites form a considerable economic resource in the region. A complete ophiolite suite southeast of the present study area, called the Divriği ophiolite (Yılmaz et al, 2001), was interpreted to have been derived from the same (i.e. Inner Tauride) oceanic basin Robertson, Parlak, Metin, et al, 2013).…”

“…The Late Cretaceous Divriği (Sivas) ophiolite, tectonically resting on top of the Munzur limestone (Tauride platform), is located between Çetinkaya and Divriği (Sivas) towns in east-central Anatolia and consists of, from bottom to top, an ophiolitic melange, metamorphic sole and remnants of oceanic lithosphere (mantle tectonites, cumulates, isotropic gabbro and sheeted dykes) Yılmaz, Arıkal, & Yılmaz, 2001). The Divriği ophiolite formed in a suprasubduction zone setting above a north-dipping intra-oceanic subduction zone within the Inner Tauride Ocean .…”

Number of dismembered ophiolite bodies crop out between Sivas and Malatya on the top of the Eastern Tauride platform in the central-eastern Turkey. One of which at the southern margin of the Sivas basin in the Tecer Mountain area comprises melange and the lower part of an oceanic lithospheric section on top of the Tauride platform. The mantle tectonites are characterized by variably serpentinized harzburgites and dunites, and are intruded by numerous isolated dykes. The gabbroic cumulates consist of olivine gabbro, gabbro and gabbronorite. The major and trace element geochemistry of the mafic cumulate rocks suggests that the primary magma was compositionally similar to those observed in modern island-arc tholeiitic sequences. The isolated dykes are exclusively basaltic in composition and display geochemically two distinct subgroups: Group I is represented by high TiO 2 (.87-1.47 wt.%) and other incompatible elements, whereas Group II is characterized by low TiO 2 (.36-.66 wt.%) and other incompatible elements. The Group I isolated diabase dykes have flat to slightly LREE-depleted profiles (La/Yb N = .32-.79), whereas the Group II isolated diabase dykes are more depleted in general and have a LREEdepleted character (La/Yb N = .19-.49). This suggests that the isolated dykes were derived from an island arc tholeiitic magma (Nb/Y = .02-.05) with different degrees of partial melting (Group II > Group I) and relatively high oxygen fugacity in intra-oceanic subduction zone. The ophiolitic rocks in the study area may well be compared with the Divriği ophiolite to the southeast. All the evidence suggests that the isolated dykes in the Tecer Mountain area differ from the alkaline isolated dykes cutting the Divriği ophiolite. Since the late stage dykes (~76 Ma) in the Divriği area are alkaline, the tholeiitic isolated dykes in the present study should have been emplaced prior to the alkaline dykes during Late Cretaceous SSZ-spreading (~90 Ma) within the Inner Tauride Ocean.

“…Su, ortamı terk ettiğinde ise bu mineraller tekrar kristalleşebilir, iyonlar yer değiştirerek yeni mineraller oluşabilir ya da mineraller birbirine dönüşebilirler. Bu minerallerin oluşturduğu kayatürlerinin egemen olduğu havzalarda su kalitesi kolaylıkla bozulmaktadır ve evaporit grubu minerallerin çözündüğü yüzey ve yeraltı suları doğal olarak kirlenmektedir [12][13]. Kuvaterner yaşlı alüvyonlar ve toprak örtü ise akarsu vadilerinde ve kimi düzlüklerde daha kalın bir düzey halinde görülmektedir (Qa, CL-ML-GW-SW).…”

ÖzYapılan çalışmada Sivas deponi alanından çıkan sızıntı sularının yarattığı kirliliğin yayılımı jeofizik ve su kimyası yöntemleri ile incelenmiştir. Sızıntı suyunun akış yönü bölgede egemen olan jeolojik süreksizlikler ve jeomorfolojik yapılar tarafından denetlenmektedir. Buna göre, yüzeydeki sızıntı suyu Haçin deresinden, yakınındaki Kızılırmak nehrine doğru akmaktadır. Bu çerçevede, Haçin deresinin iki tarafında yayılan sızıntı suyu kirliliğinin zemindeki yayılımı irdelenmiştir. Kirliliğin varlığı ve yayılımı, elektromanyetik iletkenlik (EMC-Electromagnetic Conductivity) yöntemi ve alınan su örneklerinin su kimyası analizleri ile belirlenmiştir. EMC ölçümlerinden elde edilen görünür iletkenlik grafikleri, sızıntı suyunun yataydaki yayılım sınırlarını göstermiştir. Su kimyası analizleri ise sudaki kirliliğin sızıntı suyundan kaynaklandığını göstermiştir. Sonuç olarak yöredeki Kuvaterner yaştaki toprak örtünün yanı sıra yüzey ve yeraltı su kaynaklarının sızıntı suyundan ileri gelen kirliliğin tehdidi altında olduğu belirlenmiştir. Oluşan kirliliğin ise katı atık deponi alanının daha uzun süre kullanılacağı gözetilerek, acilen ÇED (Çevresel Etki Değerlendirme) süreci çerçevesinde denetim altına alınması gerektiği ortaya konulmuştur. AbstractIn the study, the pollution spread out by the leachates coming from the disposal area (Sivas) has been studied with geophysical and the water analyses methods. The flow direction of the leachates is controlled by geological discontinuities and geomorphological structures, dominant in the region. Accordingly, the leachate in the surface flow from the Haçin creek to nearby Kızılırmak river. In this framework, the leachate pollution spreading in the underground of both sides of the Haçin creek has been studied. The leachate spreading in the underground has been evaluated by using the methods of Electromagnetic Conductivity (EMC) and the water analyses of samples obtained from the soil. Apparent conductivity graphics have been obtained from EMC measurements. The water analyses data show that the pollution in the leachate has been originated from the leachate. As a result, it has been identified that the underground and surface water resources, as well as Quaternary soil cover in the region are under the risk of the leachate pollution. Considering the solid waste landfill area to be used for a long period of time, it has been demonstrated that the pollution should be taken urgently under control within the framework of the EIA (Environmental Impact Assesment) process.

“…In fact, the disposal of hazardous wastes is the final and vital step of an effective hazardous waste management plan (Visanathan 1996). Locating a landfill in a place with the least impact on the environment has been researched by a large number of scientists and organizations (Yilmaz and Atmaca 2006;Sener et al 2006;EPA 2005;BCRC 2005;Leao et al 2004;Dörhöfer and Siebert 1997;Bell 1998;Siddiqui et al 1996;Lohani et al 1997). The appropriate site selection will have substantial effect on minimizing contamination potential and also on decreasing environmental monitoring costs.…”

The disposal is the final step of any hazardous waste management plan. An inappropriate landfill site may have negative environmental, economical, and ecological impacts. Therefore, landfills should be sited carefully by taking into account various rules, regulations, factors, and constraints. In this study, candidate sites for hazardous landfills in the northeastern Khorasan Razavi province are determined using the integration of geographic information system and landfill susceptibility zonation methods. For this, the inappropriate areas were first removed from the model, and the suitability of remaining regions were evaluated using 15 different criteria in two steps. With this done, nine candidate sites were selected as the most suitable locations. Finally, the selected landfill sites were proposed based on environmental impact assessment (Leopold matrix) and economical studies. This study shows that Maasumabad, Kheirabad, Mayamey, and Yonsi are the best locations for the constitution of landfill in Khorasan Razavi province, respectively.
