The Tauride Belt Ophiolites in southern Turkey are located on both sides of the E–W-trending, Mesozoic carbonate platform. They comprise Lycian, Antalya, Beyşehir, Mersin, Alihoca and Pozantı-Karsantı ophiolites from west to east. Each ophiolite has a metamorphic rock unit either at base peridotites or mélange units. sole rocks generally consist amphibolite top near contact with overlying tectonized harzburgite ophiolites, mica schists mostly base, tectonic underlying ophiolitic mélange. 40...
In the Lesser Caucasus and NE Anatolia, three domains are distinguished from south to north: (1) Gondwanian-derived continental terranes represented by South Armenian Block (SAB) Tauride–Anatolide Platform (TAP), (2) scattered outcrops of Mesozoic ophiolites, obducted during Upper Cretaceous times, marking northern Neotethys suture, (3) Eurasian plate, Eastern Pontides Somkheto-Karabagh Arc. At several locations along Neotethyan slivers preserved unmetamorphozed relics now-disappeared...
Abstract The Antalya and Lycian ophiolites are situated in the western part of Tauride belt (SW Turkey). Ophiolite‐related metamorphic sole rocks observed either at base tectonites or mélange units. Geochemical observations from Köyceğiz ophiolite indicate three different geochemical affinities: mid‐ocean ridge basalt (MORB), island‐arc tholeiite (IAT) within‐plate (WPB) seamount present ophiolites. made up amphibolite, comprising mainly amphibole, pyroxene plagioclase. Below amphibolites...
The metamorphic sole rocks observed between the Pozantı–Karsantı ophiolite and melange unit are located on eastern part of Tauride carbonate platform. They consist ortho-amphibolites at top metasedimentary lithologies base. Amphibolites from represented by OIB, MORB IAT based their major, trace REE compositions. isolated dolerite dykes intrude both ophiolitic different structural levels. cutting enriched in LILE depleted HFSE. Enrichment such as Th, relative to HFSE, is indicative presence a...
The Late Cretaceous accretionary complex of the İzmir–Ankara–Erzincan suture zone, near Artova, is composed mainly peridotites (variably serpentinized), amphibolite, garnet-micaschist, calc-schist, marble, basalt, sandstones, neritic limestones. metamorphic rocks were interpreted as sole occurring at base mantle tectonites, because: (i) amphibolites observed together with serpentinized suggesting their occurrences in oceanic environment; (ii) foliation and run subparallel to each other;...
The Late Cretaceous Pınarbaşı Ophiolite (PO), located at central Turkey is represented by distinct rock types (e.g., harzburgite, dunite, pyroxenite, gabbro) that can be observed in many ophiolites around the world. In this study, classification of PO Eastern Tauride Belt (Turkey) was made using advanced spaceborne thermal emission and reflection radiometer Landsat‐8 satellite images. developed colour–band ratio composite images together with principal component analysis minimum noise...
The late Cretaceous accretionary complex along the İzmir–Ankara–Erzincan suture zone, northern Turkey, includes various types of metamorphic rock together with radiolarite, sandstone, mudstone, serpentinite, basalt and limestone. Meta-plagiogranite blocks (up to 5 m in diameter) a meta-gabbro slice (800 × 500 m) cross-cut by meta-plagiogranite are observed matrix mudstone radiolarian chert. These meta-gabbros meta-plagiogranites show subduction-related geochemical characteristics. Laser...
Unusual carbonate dykes, which have a thickness of up to 4 m, cross-cut the amphibolites from high-grade metamorphic rocks in Armutlu Peninsula (NW Turkey). They are described as carbonatites on basis their petrographic, geochemical and isotope-geochemical characteristics. The carbonatites, commonly show equigranular texture, composed calcite clinopyroxene with other minor phases plagioclase, mica, garnet, K-feldspar, quartz, epidote, titanite opaque minerals. contain abundant xenoliths...
The Mamu Dağı ophiolite, ca. 13 km long and 5 across (Tokat, Sakarya Zone), consists of peridotites, pyroxenites, gabbros, basalts, which are crosscut by dolerite dykes. These rocks show variable degrees serpentinization alteration. Gabbroic consisting plagioclase + clinopyroxene ± orthopyroxene olivine amphibole sphene opaque minerals have commonly the ophitic cumulate textures. Similar mineral paragenesis is observed in basalts dolerites, characterized sub-ophitic microlitic porphyric...
Abstract The Sakarya Zone of northern Turkey contains a well-preserved Early–Middle Jurassic and Late Cretaceous submarine magmatic arc constructed over pre-Jurassic bedrocks that are considered to be the eastward extension Armorican Terrane Assemblage in Europe. In this study, we present U-Pb-Hf isotopic data from detrital zircons middle Permian Lower sandstones reveal episodes Paleozoic–early Mesozoic flare-ups. Detrital zircon ages, together with literature, define three major age groups...
Metamorphic sole rocks of the Pınarbaşı Ophiolite are one best-preserved rock units observed along Tauride Belt in Turkey. The metamorphic as tectonic slices at base mantle tectonites well blocks mélange consist mainly garnet-clinopyroxene-amphibolite, garnet-amphibolite, amphibolite, epidote-amphibolite, quartz-amphiboleschist and metabasalt. amphibolites display a wide range geochemical signatures such those N-MORB, E-MORB, OIB IAT. metabasalts exhibit characteristics. P-T estimates...
