Geochemistry And Tectonic Signifi Cance Of The Ophiolitic Rocks Of The Yarpuz-Kaypak (Amanoslar, Osmaniye) Area, Tamer Rizaoğlu, Utku Bağci, Osman Parlak
Geochemistry And Tectonic Signifi Cance Of The Ophiolitic Rocks Of The Yarpuz-Kaypak (Amanoslar, Osmaniye) Area, Tamer Rizaoğlu, Utku Bağci, Osman Parlak
Bulletin of the Mineral Research and Exploration
Yarpuz-Kaypak (Osmaniye) region, located in Amanos Mountains, contains harzburgitic tectonites and mafic cumulates. The tectonites are represented by serpantinized harzburgites, whereas the cumulates are characterized by gabbronorite and gabbro compositions. The crystallization order within the cumulates is clinopyroxene, orthopyroxene plagioclase and amphibole. The major element compositions of the tectonites and cumulate rocks are consistent with formation in an arc-related tectonic setting. Trace element concentrations of these rocks exhibit large ion litophile element enrichments. Both geochemical and petrographic evidence suggest that the tectonite and cumulate rocks from the Yarpuz-Kaypak (Osmaniye) region represent the remnants of an oceanic lithosphere that formed in …

The Rare Earth Elements (REE) deposits and mineralization of Turkey can be divided into four types based on their geological setting and origin. First are deposits associated with carbonatite- alkaline magmatic rocks, rich in Light Rare Earth Elements (LREE). The best known examples are the Kızılcaören (Eskişehir) and Kuluncak (Malatya) deposits with TREE grades of 2.9% and 0.7% respectively, and typical enrichment of La-Ce. Lower grade REE mineralization at Keban (0.05% TREE) and Divriği (0.13% TREE) is associated with abundant fluorite and all four occurrences show similar ranges for homogenization temperatures and salinities for fluid inclusions in fluorite and REE …
Paleoseismological Catalog Of Pre-2012 Trench Studies On The Active Faults In Turkey, Şule Gürboğa, Oktay Gökçe
Paleoseismological Catalog Of Pre-2012 Trench Studies On The Active Faults In Turkey, Şule Gürboğa, Oktay Gökçe
Bulletin of the Mineral Research and Exploration
Instrumental and historical earthquake catalogues have to be examined and evaluated to understand the long-term seismic behaviour of active faults. Although the instrumental records have been determined from the national and international observatories, the historical seismic catalogues are very limited in Turkey. For the reason, we aimed to compile paleoseismological trench studies carried out before 2012 in the areas of onshore and offshore sections of Turkey. In terms of a Turkey Paleoseismological Project (TURKPAP) posted by General Directorate of Mineral Research and Exploration (MTA) in the 2012 year, a number of paleoseismological investigations have been initiated and documented for archiving …
