  • Mineralogical, Petrographical, and Geochemical Properties of the Late Oligocene Coal Seam (Seam-VI): Insights into Elemental Enrichments and Palaeodepositional Environment (İbrice field, Thrace Basin)
    Ali İhsan Karayiğit, Rıza Görkem Oskay, Cüneyt Bircan
    Yerbilimleri Earth Sciences, 2024
    The Thrace Basin hosts several mineable coal seams (upwards numbered I to VII) within the coal-bearing Late Oligocene-age Danişmen Formation. For the first time, the properties of the Seam-VI in the İbrice (Malkara) area have been investigated in order to evaluate elemental enrichments and palaeoenvironmental conditions. The xylite-rich and mineral-rich lithotypes were identified from the studied coal samples representing the whole-coal thickness. The coal samples, on a dry basis, display variable ash yields (13.2–63.0%), total C (21.2–57.8%), and total S (0.9–4.1%) contents. The minerals identified using XRD-whole rock analysis include clay minerals, quartz, pyrite, calcite, dolomite, and feldspars. Siderite is only identified in a single sample. Aragonite is detected in two samples, which contain fossil shell remains. The SEM observations agree with XRD data, and apatite, barite, biotite, pentlandite, sphalerite, Ti-oxide, and zircon were also identified as accessory phases. Huminite is the predominant maceral group in the studied samples, while liptinite and inertinite group macerals display variable proportions. The mean %Rr values of ulminite macerals are around 0.40-0.41±0.01-0.02%, indicating relatively low-rank coal. This study implies that the precursor peat-mires of the Seam-VI were mainly developed under forested mire conditions, where woody peat-forming plants were abundant, and occasionally the contributions of herbaceous plants were important. The coexistence of syngenetic pyrite and carbonate minerals (e.g., siderite and carbonate mineral bands) could be related to the development of weakly acidic to neutral conditions within palaeomires. Furthermore, the predominance of clay minerals and the presence of detrital accessory minerals (e.g., apatite, pentlandite, and Ti-oxides) can also be indicators of clastic influx into palaeomires. Although aluminosilicate minerals (e.g., clay minerals) are abundant in dominant phases, SEM-EDX data shows that accessory minerals mainly control the elemental enrichments in the Seam-VI. The Mn enrichments in the samples seem to be controlled by Mn-bearing siderite micronodules. Considering the presence of sulphide mineralization and metallic ore deposits in the Strandja and Rhodope massifs, enrichments of Cr, Co, Ni, Ge, and Mo are related to As-bearing pyrite grains and accessory sphalerite and pentlandite grains within clay mineral aggregates in the samples. In addition, the Sr-bearing barite overgrowths around feldspar grains and syngenetic carbonate mineral bands could also cause Sr enrichments. Overall, clastic influx ratios into palaeomires and pH conditions during peat accumulation controlled the elemental enrichments in the Seam-VI.

  • Opinions and comments on the benthic foraminiferal assemblage observed around the mineral submarine spring in Kuşadasi (Aydin, Turkey)

    Review of Symbolic Logic, 2014
    The aim of the study was to investigate the benthic foraminiferal fauna around the mineral water spring in Pamucak Cove, north-west Kuşadası (Aydın) and figure out the effects of the spring on the fauna. The spring was located 200 m off the coast at 12.4 m depth and its temperature was 19.6°C. The study area was found to include a rich population of Red Sea originated Amphistegina lobifera, of which the distribution pattern is noteworthy. It is abundant in the centre of the spring and its close vicinity; its abundance decreases when getting away from the spring. It is more abundantly observed on the southern and western sides of the spring, whereas, it is outnumbered by Ammonia compacta and Elphidium crispum on the northern and eastern parts. The water currents around the spring were in north–south and north–west directions. The observed diverse diatom population around the spring constitutes the main food source and dispersal according to the currents may explain the reason for the abundance of the Amphistegina population on the southern and western sides of the study area. High abundances of A. lobifera have not yet been observed elsewhere in the Aegean Sea, although large populations of this species have been recorded on the south-west coasts of Turkey and in several stations on the south-east of Gokceada. Abundance of coloured individuals and Red Sea originated benthic species suggests the presence of special environmental as well as ecological conditions around the spring.
  • Relationships of benthic amphipod communities with environmental variables in the shallow waters of the Dardanelles

    The structure of the benthic amphipod assemblage and its relationship with soft-bottom characteristics (particle size, organic matter, etc.) of the coastal waters at the depths of 0–5 m at the Dardanelles, including the Turkish Straits System, was studied. A SCUBA diver took benthos and sediment samples seasonally using a quadrate system of 30×30 cm as three transects from the 8 different stations between July 2008 and April 2009. A total of 3007 individuals belonging to 50 species was reported. Among these, Corophium acutum Chevreux, 1908 had the highest dominance value (Di%=22.18) and the lowest dominance value belonged to Dexamine thea Boeck, 1861 (Di%=0.03). The highest positive correlation (rs=0.57, p<0.05) was observed between the gravel content (%) and the abundance (ind. m−2). The highest sand rate (99.59%) in the sediment was found at the Eceabat site. The lowest rate was at the Kepez Harbour station with a value of 73.01%. The highest H′ value (1.53) was recorded at the Eceabat site, and the lowest H′ value (H′=0.95) was recorded at the Gallipoli sampling station.
  • An oasis for alien benthic foraminifera in the Aegean Sea

    Aquatic Invasions, 2010
    The benthic foraminiferal fauna in Pamucak Cove (NW Kusadasi, Turkey) was investigated. A rich foraminiferal assemblage was observed around submarine springs, which were located 200 m off the coast. This foraminiferal assemblage is typical Mediterranean. However, the abundance of alien species is noteworthy. Fourteen alien foraminifera were found. Indo-pacific originated species; Quinqueloculina sp. C, Triloculina sp. A, Pyramidulina catesbyi (d’Orbigny), Brizalina simpsoni (HeronAllen and Earland) and Amphistegina lessonii d’Orbigny were observed for the first time on the Turkish coastline. Specimens of Haddonia sp. and Cymbaloporetta plana (Cushman), abundantly observed in SW Antalya and Nodopthalmidium antillarum (Cushman), previously recorded from Iskenderun were also found in the study area, these are the first records for these species in the Aegean Sea. In addition, seven individuals of Euthymonacha polita (Chapman) were found around the springs, and this constitutes the first record of this species in the entire Mediterranean Sea.
