The mineralogy, texture and composition of rocks associated with the kaolin deposits in the Ahirozu-Hamidiye-Ucbasli area, SE of Mihaliccik, Eskisehir, Turkey, were investigated. In the study area, Triassic, blue-green schists and serpentinized ultramafic rocks are exposed. Kaolinization occurs at the contact between a Triassic granitic intrusion and metamorphic rocks. Textural and mineralogical characteristics were identified by X-ray diffraction (XRD) and scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) analyses. The effects of hydrothermal alteration on the whole-rock chemical composition were determined by inductively coupled plasma mass spectrometry (ICP-MS) analysis. Homogenization temperature (T-h, degrees C), salinity, (wt.% NaCl) and melting temperature (T-m, degrees C) were detected by fluid-inclusion analyses.

Geochemical constraints on the Cenozoic, OIB-type alkaline volcanic rocks of NW Turkey: Implications for mantle sources and melting processes ALDANMAZ, ERCAN; KÖPRÜBAŞI, NEZİHİ; GÜRER, ÖMER FEYZİ; Kaymakcı, Nuretdin; Gourgaud, Alan (Elsevier BV, 2006-01-01) The volcanic province of North-West Turkey contains a number of intra-continental alkaline volcanic eruption sequences formed along the localized extensional basins developed in relation with the Late Cenozoic extensional processes. The volcanic suite comprises the extracted melt products of adiabatic decompression melting of the mantle that are represented by small-volume intra-continental plate volcanic rocks of alkaline olivine basalts and basanites with compositions representative of mantle-derived, pri...
Hydrogeochemical outline of thermal waters and geothermometry applications in Anatolia (Turkey) Mutlu, Halim; Güleç, Nilgün Türkan (Elsevier BV, 1998-10-01) The chemical compositions of a total of 120 thermal water samples from four different tectonically distinct regions (Central, North, East and West Anatolia) of Turkey are presented and assessed in terms of geothermal energy potential of each region through the use of chemical geothermometers. Na-Ca-HCO3, type waters are the dominant water types in all the regions except that Na-Cl type waters are typical for the coastal areas of West Anatolia and for a few inland areas of West and Central Anatolia where dee...
Sub-ophiolite metamorphic rocks from NW Anatolia, Turkey Onen, AP; Hall, R (Wiley, 2000-09-01) The metamorphic rocks from near Kutahya in north-west Anatolia record different stages in the history of closure of the Neo-Tethyan Izmir-Ankara-Erzincan ocean. Sub-ophiolite metamorphic rocks within the Tavsanli zone are a tectonically composite sequence of quartz-mica schists, amphibole schists, amphibolites and garnet amphibolites. They show increasing metamorphic grade towards the base of the ophiolite. A first metamorphic event, typical of sub-ophiolite metamorphic sole rocks, was characterized by high...
SEISMIC STRATIGRAPHY OF THE FAULT-CONTROLLED SUBMARINE-CANYON VALLEY SYSTEM ON THE SHELF AND UPPER SLOPE OF ANAMUR BAY, NORTHEASTERN MEDITERRANEAN-SEA EDIGER, V; OKYAR, M; ERGIN, M (Elsevier BV, 1993-11-01) High-resolution shallow seismic reflection (Uniboom) and echosounding profiles obtained on the shelf and upper slope areas of Anamur Bay (Turkey, northeastern Mediterranean) were studied together with previous data on the onshore geology of the area to investigate the origin and related seismic stratigraphy of the submarine Anamur Canyon. It was found that the main axial trend of the submarine Anamur Canyon is aligned with the offshore projection of the N-S orientated, onshore Anamur thrust fault of Late Cr...
SEISMIC STRATIGRAPHY AND LATE QUATERNARY SEDIMENTS IN INNER AND MID-SHELF AREAS OF EASTERN MERSIN BAY, NORTHEASTERN MEDITERRANEAN-SEA ERGIN, M; OKYAR, M; TIMUR, K (Elsevier BV, 1992-02-29) High-resolution shallow-seismic reflection (Uniboom) profiles obtained in inner and mid-shelf areas of eastern Mersin Bay (Turkey, northeastern Mediterranean) show that the sedimentary column comprises two major and distinct lithological sequences (C and B) separated by a reflector (R) which is interpreted as the pre-Holocene surface. The upper sedimentary sequence (C) is thought to represent roughly the Holocene and is characterized by parallel/divergent to sigmoidal reflection patterns above (Unit 1) and ...
