Biostratigraphical observations in Pliocene deposits of Heraklion Province, Crete. Skythia section
No full textCalcareous nannofossils, planktonic foraminifera and mollusc associations have been studied in order to define the biostratigraphical and chronostratigraphical position of a sequence of marly and diatomaceous Neogene sediments (Skythia section, Heraklion province, central Crete). The integrated analysis indicates a Pliocene (Lower Piacenzian) age.
Additional paleoecological observations certify the presence of a rather shallow warm-temperate depositional environment.Observations stratigraphiques sur les dépôts du Pliocène de la Province de Heraklion, Crête. La coupe de Skythia.
Nannofossiles calcaires, foraminifères planctoniques et associations de mollusques ont été étudiés pour définir la position stratigraphique et chronostratigraphique des sédiments néogènes de la section Skythia (Heraklion province, Crète centrale). L'intégration des résultats de l'analyse a indiqué que l'âge des sédiments est pliocène (Piacenzian inférieur).

Desain Konstruksi Kapal Penumpang M.V Putri Hijau Penyebrangan Kecamatan Belawan-Desa Batang Serai
No full textABSTRACT
Construction is an activity to build facilities and infrastructure. In addition, construction can also be interpreted as buildings or infrastructure units in one or several areas. In the final project of Delta Liona Aritonang with the title Planning of Passenger Ship Design as a Means of Transportation in Batang Serai Village, the author has made a passenger ship design under the name M.V. Putri Hijau. The author has previously designed a line plan and general arrangement. The author's goal is to get construction calculations from the passenger ship M.V. Putri Hijau, get a construction profile picture on the passenger ship M.V. Putri Hijau.

Tourism Ship Design to Support Tourism on Lake Toba, the author has created a tourist ship design with the name M.V. Sitoba. The previous author has designed the lines plan and general arrangement. The results of this study are to get the modulus calculation of each component on the M.V. Sitoba, Transverse Frame = 17,57 cm³, Side Longitudinal = 21,36 cm³, Side Girder = 20,76 cm³, Tunnel Longitudinal = 18,99 cm³, Bottom Longitudinal = 25,737 cm³, Deck Girder =
13,183 cm³, than obtain the thickness of the fiberglass layer on all sides, and obtain a 3D construction drawings on the M.V. Sitoba tourist ships uses autocad software

The Barremian and Aptian stepwise development of the 'Oceanic Anoxic Event 1a' (OAE 1a) crisis: integrated benthic and planktic high-resolution palaeoecology along the Gorgo a Cerbara stratotype section (Umbria-Marche Basin, Italy)
No full textThe Barremian and Aptian were times of global plate reconfiguration and profound changes in the ocean-climate system, culminating in the worldwide deposition of lower Aptian black shale layers (OAE 1a). Based on high-resolution lithostratigraphic and micropaleontological analyses, precursor conditions and timing of the anoxia are here reconstructed along a 33.06 m thick section in the proposed Barremian/Aptian boundary GSSP stratotype at Gorgo a Cerbara (Umbria-Marche Basin, Italy).
A non-uniform history of benthic foraminiferal diversification is interrupted by the Selli Level (= OAE 1a) and by three turnover points for both benthic and planktic organisms, each highlighted by prominent breaks in lithology and outcrop morphology. The first two points, at similar to 1.1 Myr and similar to 20-50 kyr prior to the onset of the OAE 1a, correspond respectively to the nannoconid (= bathypelagic calcareous nannofossils) 'decline' and 'crisis' events, and separate: (a) pelagic limestone/chert-claystone lithological cycles of the uppermost Maiolica Formation, showing frequencies reminiscent of orbital eccentricity and containing an oligotrophic Barremian benthic and planktic assemblage, dominated by k-selected nannoconids and Rhizammina; (b) greenish-grey cherty marls of the lowermost Marne a Fucoidi Formation, associated to declining sedimentation rates and eutrophic early Aptian assemblages dominated by radiolarians and lituolid benthic foraminifera; and (c) anoxic radiolarites and shales of the carbonate-free Selli Level. High magnitude and frequency assemblage fluctuations occur between the nannoconid crisis (similar to 25 cm below the lowermost OAE 1a black shale layer) and the Selli Level base, with suggestions of bottom-water acidification. At similar to 800 kyr after the OAE 1a end, a third turnover point in the basal reddish member of the Marne a Fucoidi highlights 'middle' Aptian assemblages characterized by a bloom of early macroperforate planktic foraminifera (Hedbergella spp.) and appearances of new benthic species, marking a shift towards better oxygenation.
OAE 1a oxygen and pelagic carbonate factory crises are here suggested to have been step-wise and linked to global warming conditions

Calcareous nannoplankton dating of the Late Quaternary deposits in Greece and the eastern Mediterranean: Case studies from terrestrial and marine sites
No full textAbstractThe distribution and abundance of Emiliania huxleyi (E. huxleyi) assemblages in the marine sediments of the Aravonitsa Plateau, Greece, and from the eastern Mediterranean are used (1) to evaluate the calcareous nannoplankton NN21a and NN21b biozones and the NN21a/NN21b boundary, and (2) to analyze the palaeoenvironmental and palaeoclimatic conditions prevailing in this interval. The sediment succession displays varied E. huxleyi assemblages and these are interpreted as reflecting climatic variability during marine isotope stages MIS 1–8

Quantitative micropaleontological analysis and paleoenvironmental interpretation of Southern Kerkyra Pliocene deposits
No full textThe section Kontres (Pliocene-Lower Plaisancian) is located in the southwest side of the island of Kerkyra. The sedimentary facies ana¬ lysis leads to the recognition of open sea sediments (basal part of the section ) which are coarsening-upwards into coastal sediments characterized by processes of alternating low -and high energy. Randomly, the above-mentioned deposits are influenced by flood-generated currents. The quantitative micropaleontological analysis of calcareous nannofossils shows a trend for higher temperatures concerning the surface waters of the depositional environment. In addition, bottom water conditions have been estimated by benthic foraminifera and are found characterized by periodicity in the oxygen content and salinity.Analyse micropaléontologique quantitative et interprétation paléoenvironnementale des dépôts pliocenes du Sud de Corfou. La
section Kontres (Pliocène inférieur -Plaisancien) est localisée à la côte sud-ouest de l'île de Corfou. L'analyse des faciès sédimentaires, conduit à la reconnaissance des sédiments de haute mer (base de la section) qui deviennent vers le haut des sédiments de plus en plus grosiers, côtiers, caractérisés par un processus d'énergie alternativement, basse et haute. Au hasard, les dépôts mentionnés ci-dessus, sont soumis à l'influence des courants marins. L'analyse micropaléontologique quantitative des nannofossiles calcaires démontre une tendance vers des températures plus hautes des eaux de surface à l'entourage des dépôts. De plus, les conditions des eaux au niveau du fond ont été estimées par les foraminifères benthiques et sont caractérisées par des variations périodiques de la salinité et du taux d'oxygène dissous.Triantaphyllou M.V., Drinia H., Dermitzakis M.D. Quantitative micropaleontological analysis and paleoenvironmental interpretation of Southern Kerkyra Pliocene deposits.

Calcareous nannofossil dating of Ionian and Gavrovo flysch deposits in the External Hellenides Carbonate Platform (Greece): Overview and implications
No full textThe available biostratigraphic data based on calcareous nannofossil analysis determine the mean ages for the onset of flysch sedimentation (base of transitional beds) of the Ionian unit at ~. 34-35. Ma (external/internal Ionian), and at ~. 41. Ma (middle Ionian). The top of the Ionian flysch at ~. 25. Ma constrains the emplacement of Gavrovo nappe, providing an average duration of at least 11-16. Myr for the flysch sedimentation. Gavrovo flysch deposition started at a mean age of ~. 34. Ma and lasted till ~. 29. Ma (emplacement of Pindos nappe), suggesting an average duration of approximately 5. Myr. Phenomena of synsedimentary tectonism have been reported at the external Ionian unit, indicating that pre-flysch extension of the basin lasted at least 4. Myr. The ~. 6-7. Myr difference of the onset of flysch sedimentation between the external/internal and middle parts of Ionian unit implies evidence for an axial symmetry of the basin before the underthrusting of Mani unit under Pindos nappe. © 2012 Elsevier B.V
