Field Trip Details
Underground Nuclear Waste Storage and Wine Cellars in the Paris Basin
This one day excursion will combine a visit to a french laboratory for the study of nuclear waste storage with a visit to one famous champagne wine cellar.
The major research facility of the French National Radioactive Waste Management Agency (ANDRA) is situated in Bure (Meuse). Its goal is to study the feasibility of the reversible geological disposal of high-level and long-lived intermediate-level radioactive waste in the 160 My old Callovo-Oxfordian clay formation. The underground laboratory uses 1.5 km of underground galleries 490 meters below the surface. The visit will first start by the visitor center showing the geological context and the history of the development of the project. It will continue in the underground laboratory with the scientific installations in the galleries.
The Champagne region is famous worldwide for producing the famous bubbling Champagne wine. Either on the way to Bure or back from Bure, we will stop in Reims or Epernay to visit a selected famous underground winery where Champagne wine is ageing 30 m below the surface in the typical limestone sub-soil of the region. The 1 hour visit will include a wine tasting.
One day excursion, one on Friday 4 August, one on Saturday 5 August
- depart (7am) from Porte Maillot and return (9:30pm) to Porte Maillot
- private bus transportation
- 25-30 participants
- the fee include transportation by bus from and back to Paris center, admission to the wineries and sandwich-type lunch.
The South Armorican Shear Zone: exhumation of migmatites, emplacement of syntectonic granites and fluid-rock interaction
The South Armorican Shear Zone (SASZ) is one of the major Variscan deformation zones in Western Europe. It allowed exhumation of high-temperature (HT) units in the South. In addition, numerous syntectonic granites were emplaced during tectonic activity either along the SASZ itself, or along low- angle detachments. Finally, evolution to conditions of brittle deformation permitted the infiltration and circulation of surface-derived fluids in upper crustal levels.
During this 3-days field trip, we will visit outcrops symptomatic of these events.
Sedimentary geology in the gold coast vineyard and wine tasting
Geological Background of the gold coast excursion:
- Southeast limestone ridge of the mid-Jurassic (ca. 170 million years ago) Paris Basin
- Eastern Border of the Bresse Cenozoic rift valley
- The geomorphology of the area is controlled by quaternary glaciation
- Outcropping geology is made of limestone deposited during the greenhouse period of the mid-Jurassic in shallow marine environment.
- Abundant remains of well-preserved coral reef, bivalves and gastropods are well exposed between the rows of vines and in quarries.
- Diagenetic processes such as dolomitization and flint nodules formation can also be easily observed.
The field trip will be organized and guided by researchers from University of Burgundy (UMR CNRS 6282 Biogéosciences).
The Variscan Velay migmatite-granite Dome: growth and reworking of the crust through magmatic-metamorphic processes in an orogenic root
The field trip will show a series of spectacular outcrops (mostly polished river beds and similar) featuring:
- Ediacaran ortho-and paragneisses, that are the building blocks of the Variscan belt in Central France;
- LP/HT migmatites and granites recording partial melting of the Ediacaran crust (ortho and paragneisses);
- Mafic Mg-K rocks and associated granites.
We will discuss the origin and evolution of each rock type; their mode of formation, P—T evolution and petro/geochemical signature (based on large data recently produced by our group); and the respective role of crustal growth vs. recycling in an orogenic root.
The trip will be held in the Ardèche mountains of Southern France and will offer opportunities to sample local pleasures including country food, local wine, great landscapes and beautiful swimming holes in mountain streams.

Geology and Mineralogy of the Swiss Alps
Switzerland is an expensive country, but it is well-known for secular traditions of tourism. This feature leads to the best quality transportation system, breathtaking landscapes, and evidence of various tourist attractions for people in every occupation.
The most popular surname in Switzerland comes from the German word that means 'miner.' Thus, it is no marvel that there are many geologic showplaces in the country. We suggest visiting some of them during 4 days.
- Käpfnach Coal Underground Mine in Horgen, and Urner Mineralien Museum in Seedorf
- Lengenbach dolomite quarry and its storage room, mineralogical museum of Andre Gorsatt, and Local Museum of Binn Valley
- Locality with the classic alpine veins in the suburbs of Tchappina Village
- Bex Salt Mine, “Focus Terra” Museum at ETH (Zurich)
- and even functioning Nuclear Power Plant and Radioactive Waste Storage in Aarau Region
The main criteria for choosing tourist attractions for this journey were as follows: a) easy accessibility for people of all ages, b) distinct geological types of rocks/mineralisations and different types of mines (e.g., underground or on the surface, abandoned or operated, etc.), and, c) vast geography of attractions. The last criterion will allow us to see all kinds of Swiss sceneries and cultural peculiarities during the train ride across the country.
Moreover, participants of this trip would have the possibility to explore some points of geological interests that are usually closed to the public (e.g., the inner part of the Lengenbach quarry or storage room of the "Focus Terra" geological museum in Zurich).
The cheapest way for travelling from Paris to Zurich is regular FlixBus (tickets cost 40-50Euro per person).
