Description of the thesis topic

The originality of this thesis will be based on the linking of the unique collection of the Morée Expedition preserved in the rock collections of the National Museum of Natural History, the geology of the marble quarries of the Cyclades (Delos, Rhénée, Mykonos, Paros, Naxos and Tinos) and the construction stones of the site of Delos by a whole range of portable instruments.
It will take place in two stages: 1) creation in the laboratory of a lithothèque of reference of the marbles resulting from the Morée expedition, historical collection that we increment during our missions in Greece with Lorent Jolivet (IsTEP). These samples will be analyzed for miners and traces in laser ICPMS, for isotopes of oxygen and carbon in mass spectrometry; 2) Calibration of a portable X-ray fluorescence instrument and non-destructive in situ analysis of marble in the ancient city and sanctuary of Delos.
• Methods envisaged: ICPMS Laser, X Florescence, X-ray diffraction, Mass Spectrometry, Optical Microscopy and Scanning Electronics.
• Expected results, publication strategy: traceability of the marbles in the structure delien in order to go back to the exchanges (of VII ème before JC to IIème century after JC) between the sanctuary island not only with the Cyclades but also with the mainland Greece (l Attica
mainly). Outlets in terms of publications will be the following journals: Global and Planetary Change, Geomorphology: Embossed Processes and Measurements. Journal of Geological society

• Possibility of reorientation: the constitution of this lithotchic with contemporary analytical instruments is in itself a major objective in the research on collections within the MNHN
• Feasibility in three years, schedule:
-From November 2019 to July 2020: chemical analyzes of the marbles collected in 2017 and 2018 in the outcrops and ancient quarries of the island of Delos outside the archaeological site, in the surrounding islands and in continental Greece.
Calibration of portable X-ray fluorescence.
-Spring 2020: Field mission to Delos with analysis of the marbles in situ in the archaeological building with portable X-ray fluorescence and new reasoned sampling campaign in the marble quarries of the Cyclades
-2020-2021: Confrontation with existing databases and return to the field with a Raman and a portable LIBS
-2021-2022: Summary and writing

Work Context

This thesis dedicated to metamorphic rocks rich in carbon marble will be held at IMPMC on the Buffon site in the ROCKS team whose core business is rock petrography with a strong emphasis on the carbon element. 'IMPMC UMR 7590 of 200 people is spread over two Paris sites and the MNHN (Buffon Polivot island). The thesis will take place on the MNHN site in the Rocks team led by Sylvain Bernard and which has 8 permanent and 6 non permanent (PhD and post doc). The thesis will be directed by Violaine Sautter, research director of 1st class and member of the ROCKS team. Our Engineer Sylvain Pons responsible for Health and Safety on the Buffon site will frame the future Thesard at the level of portable X-ray fluorescence and SEM.

Constraints and risks

This thesis does not include any specific risk with the exception of portable X-ray fluorescence with a nuclear source and for which we are all trained in particular Sylvain Pons who will be in charge of training the future doctoral student.

Additional Information

This thesis will be fincancially supported by the ANR GAD
