Something about me

Born in Athens (Athina in Greek) in 1965 - August, a beautiful but very hot season- (I think it is located somewhere in Greece ? or not? weather in Athens now?). After being educated at Patras University (Geology Dept., Diplom degree, also in Greece), I came to Germany (Free University of Berlin, Institute of Paleontology), where I completed my Ph.D. thesis (February 1997). From March 1997 to February 2002, I worked as a scientific assistant in the German Research Foundation-funded project Sedimentation dynamics on the neogene basins of Kastelli and Platanos (NW Crete island, eastern Mediterranean Sea). Since March 2002, I am employed as a part-time lecturer at the Department of Environmental Studies of the University of Aegean (Lesbos, Greece).

Awards

On December 27, 2001, I was awarded the "C. Ktenas Prize" of the Greek Academy of Sciences for my contribution to the geology of Greece (Crete Neogene Development).

RESEARCH ---pre-doctorate, but concerning my thesis---

Key Words: Calcareous nannofossils, Coccoliths, Taxonomy, Biostratigraphic Correlations, New Zonation, Middle latitudes, Paleoecology, Tertiary, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, Holocene, Stage Boundaries, Flysch, Clastic sediments, Ionian Zone and Ionian Basin, Epirus, Greece.

Thema of the thesis was the taxonomy of the calcareous nannofossils and subsequent biostratigraphic correlations between the studied sections. The investigated Formations were mainly consisted by Flysch and Flysch-like successions, belonging to the Oligocene in age Ionian Zone of Greece, Epiros (one of the External Zones of GR with an important reservoir potential). Although the difficulties due to the character of the Flysch (reworking -sometimes extreme-, poor preservation -somewhen disappointing-, rarity -sometimes even barren-, and tectonics) were a lot, a correlation of the sections was made possible with a new biozonation scheme © which has been here established.

This new biostratigraphical scheme is available by the author.©

Do not hesitate!  It realy worths!  Just contact with me (by post or e-mail).

RESEARCH ---pre-doctorate, but not concerning my thesis---

I have participated, usually as the calcareous nannofossils specialist and biostratigraphic expert or simply as a post-graduate student assistant in a lot of projects. Most important were the following:

  • Middle to Late Eocene and Oligocene of Poland (Tatra Mountain Range).
  • Late Palaeocene of Spain (clastic, turbiditic deposits, calcareous nannofossils). - Jurassic ostracodes of Spain. - Jurassic sponges and biogenic sedimentation in Spain.
  • Cretaceous calcareous dinoflagellate cysts (calcispheres) from boreholes in Germany.

CAREER

From March 1997 to February 2002, I worked as Scientific Assistant and Researcher ("wissenschaftlicher Mitarbeiter") in German language at the Institute of Palaeontology of the Free University of Berlin, on a Project financially supported by the German Research Foundation (Deutsche Forschungsgemeinschaft or DFG) and the Free University of Berlin. The Project was entitled "Sedimentation dynamics of the Kastelli and Platanos basins in NW Crete". Basin analysis is mainly based on refining of the biostratigraphic framework concerning the micropalaeontological data (calcareous nannofossils, foraminifera, silicoflagellates and Diatoms) and subsequently on establishing a sequence stratigraphic model representing the basin development during the Late Miocene to Recent time span. The project was part of the International Continental Drilling Project (Schwerpunktprogram ICDP-KTB-SPP). Main target of the project is the localisation of promising sites for a very deep drilling in the Mediterranean area. First attempt is to situate an optimum continental site (ICDP-KTB) which will permit us to correlate the results with a future offshore site (possibly available through the ODP services). Other countries in the world are trying through their researchers to be included in the target panel as well. Since 01.03.99 the Project has been expanded to another basin situated to the west of Kastelli, namely the Platanos Basin. Field work was carried out in spring time of 1999, 2000 and 2001. The results for the two sedimentary basins have been correlated with the eastern Mediterranean Sea data for the Late Cenozoic (onshore and DSDP and ODP drillings offshore). In 2002, the study area of the projects was extended to central Crete (Mesara basin).

Parallel to the research, (a) I supervised German students, teaching them firstly, during their geological field mapping on Crete/Greece (Diplomkartierung) and secondly later on while in Germany, and (b) I am giving lessons in Compact Courses on

  1. Biostratigraphic Correlations using Calcareous Nannofossils Bioevents and Standard Zones (Number in the Lessons Catalogue of the FU-Berlin: 24 165 V+Ü [V+Ü means Lesson and Exercises], between 01.03 and 03.03.99),
  2. Computer Design applications in the Geology-Stratigraphy (24156 V/Ü, maps, sections, morphology of fossils -collaborator research assistant U. Gloy-) and
  3. Possibilities and methods in the palaeontological Complex Interpretations using examples from Rumanian, Poland, Germany, Spain and Greece (24155 V+Ü, -collaborator research assistant J. Bartholdy-).

The courses include, (1) paleontological laboratory preparation techniques and exercises under the normal Light microscope (LM) and Scanning Electron Microscope (SEM) and (2) practical exercises on Personal Computers (PCs). Study material comes from my personal collection and covers different geological periods and paleoecosystems, as well as a variety of floral provinces bearing latitudinal stress (e.g. Messinian salinity crisis, Oligocene/Eocene, Oligocene/Miocene and Pleistocene/Holocene boundary events).

At last, I was invited speaker in one Workshop and four Colloquiums:

  1. Third Workshop on the development of an onshore/offshore drilling program, Chania/Crete, October 15-19, 1998: "The tectonic evolution and mechanics in the extending forearc of the retreating Hellenic subduction zone within the East Mediterranean" (ICDP-KTB Project)
  2. Second International Continental Drilling Program/Kontinentales Tiefprogram der Bundesrepublik Deutschland, ICDP/KTB-Kolloquium, Ruhr-University in Bochum, May 22 and 23 of 1997
  3. Third International Continental Drilling Program/Kontinentales Tiefprogram der Bundesrepublik Deutschland, ICDP/KTB-Kolloquium, Ruhr-University in Bochum, June 04 and 05 of 1998
  4. Fourth International Continental Drilling Program/Kontinentales Tiefprogram der Bundesrepublik Deutschland, ICDP/KTB-Kolloquium, Ruhr-University in Bochum, May 27 and 28 of 1999
  5. International Continental Drilling Program/Kontinentales Tiefprogram der Bundesrepublik Deutschland, ICDP/KTB-Kolloquium, Ruhr-University in Bochum, November 25-26, 1999.

Recent Project Participation

(3) Greece

Title: Paleoclimatological study and correlation of sediment core-material from submarine basins

Support: IKY (National Scholarships Foundation, Idryma Kratikwn Ypotrofiwn in Athens/Greece)

Project Leader: Dr. S.M. BELLAS

Project Supervisors-Instructors: Profs. D. Frydas (Geology Dept., Patras University, Greece) and D. Papanikolaou (Geology Dept., Athens University and General Director of NCMR, National Centre for Marine Research, Athens)

Objective: Paleoclimatological study and correlation of sediment core-material from the sub-sea basins between Kos-nisyros and Gyali volcanic islands, central-eastern Aegean. Correlation and response of the micro- nannoassemblages to the last Glacial maximum and to the volcanic erruptions activity.

Country: Greece

Studied sediments age: Late Pleistocene to Recent

Duration (first sector): one year (01.01.2001 - 31.12.2001)

Comment: This project mainly concerns the living and fossil plankton communities during the Holocene and latest Pleistocene stratigraphic time-interval. It operates in the frame of the NCMR studies together with other European Universities and Institutes. It will investigate the Volcanic Hazzards and the response of the organisms in such or relative sudden catastrophes. Future work will take place at the NCMR, at Patras University (Geology Dept., Micropaleontology Laboratory) and at the FU-Berlin (Institute of Paleontology -SEM). First core material is already available (November 2000), while a new cruise is planned for the next April with the R/V Aegeon of the NCMR.

Title: Sedimentation dynamic of the Neogene Platanos Basin, NW Crete island

Funding: German Research Foundation, Deutsche Forschungsgemeinschaft (Supported Project: Ke 322/1)

Project Instructor-Leader: Univ.-Prof. Dr. Helmut KEUPP

Main Participant and Representative (FU-Berlin side): Dr. S.M. BELLAS

Objective: Biostratigraphic analysis and correlation of neogene and quaternary deposits of the Platanos Basin (NW Crete). Developmemt of a sequence stratigraphic model and correlation to the Kastelli basin.

Country: Greece

Studied sediments age: Upper Miocene to Recent

Duration of my participation: one year (01.03.1999 - 29.02.2000)

Comment: This project also took place in the frame of the International Continental Drilling Program (ICDP-KTB) mentioned above. The Platanos area is located to the west of the previously studied Neogene Kastelli/Kissamou Basin. A big difference in relation to the Kastelli Basin, is that the newly investigated basin incorporates Pliocene sediments and better Pleistocene outcrops. There, the Mio-Pliocene and Plio-Pleistocene sedimentation were fairly continuous. The project is presently under process (field work was completed in the time-span of 15.03.1999 and 30.04.1999). Five students were appointed to geologically map the southern margin of the basin, to the boundary with the Preneogene strata and to find out the type of geological contacts between the Neogene and the Preneogene. A synthetic publication is in press together with Prof. H. Keupp: see publications list. The geologic-facies map (scale 1:25,000) of the two studied Neogene basins and of a third new one is also going to be published as a separate.

Title: Sedimentation dynamic of the Neogene Kastelli Basin, NW Crete island

Funding: German Research Foundation, Deutsche Forschungsgemeinschaft (Supported Projects: Ke 318/1 & 318/2)

Project Instructor-Leader: Univ.-Prof. Dr. Helmut KEUPP

Main Participant and Representative (FU-Berlin side): Dr. S.M. BELLAS

Objective: Geologic and stratigraphic analysis and correlation of neogene deposits of NW Crete. Developmemt of a sequence stratigraphic model for the last 8.5 Ma. Country: Greece

Studied sediments age: Upper Miocene and Pleistocene

Duration of my participation: Two years (01.03.1997 to 28.02.1999)

Comment: Task of this project, which runs in the frame of the International Continental Drilling Program (ICDP-KTB), was the study of the first transgressive sequences, initiation of sedimentation in relation to the preneogene srata surrounding the basin margins, estimation of the age of the transgression (pre-Messinian-event), development of the Neogene sedimentary Kastelli Basin from Late Miocene to Recent in time-intervals (slides) in steps of ca. 0.5my, and subsequently localisation of the Drilling in order to get best data at a minimum cost (subduction zone between the Aegean microplate and the African Plate, Southern Aegean Island Arc). For further details see under Career Experience. Numerous papers and posters were published during the project. A summary of the basin development is in press under Keupp & Bellas in collab. with Frydas & Bartholdy (2000), see publications list.
