6. Deep subduction of the Seve Nappe Complex in the Scandinavian Caledonides
Abstract : This thesis seeks to improve our understanding of the processes involved in continental collision zones, with a particular focus on subduction-exhumation. The main objective of this work has been to define the tectonometamorphic evolution of the deeply subducted Seve Nappe Complex (SNC) in the Scandinavian Caledonides. READ MORE

7. The metamorphic history of Naxos (central Cyclades, Greece) : Deciphering the Oligocene and Miocene exhumation events
Abstract : High pressure, low temperature (HP-LT) rocks observed at the surface of the Earth are evidence ofpast subduction zones. Understanding the tectonics processes that control the exhumation of HP-LT metamorphic rocks in these subduction zones requires full comprehension of the pressure-temperature-time (P–T–t) cycle that the rocks experienced.

8. Influence of the deep petroleum transformation on the CO2 budget of the atmosphere
Abstract : Petroleum is an important component of the Earth’s crust and a necessary agent in human life. Due to fossil fuels usage in human activities, the carbon dioxide budget of the atmosphere is growing on the 4-5 GtC/year. READ MORE

9. Earthquake Sources and Hazard in northern Central America
Abstract : Northern Central America is a tectonically complex zone defined by its borders with Cocos and North America plates. The Middle America subduction zone and the strike-slip motion along the North America-Caribbean plate boundary, in that order, control most of its deformation. READ MORE

10. Geochemical and geochronological constraints on 1.88 and 1.80 Ga magmatic events in the Gällivare area, northern Sweden
Abstract : The Gällivare area is situated in northern Norrbotten, Sweden, and hosts the Aitik Cu-Au deposit and the Malmberget Fe deposit. In addition, more than 17 mineral prospects and mineralizations are present, among these the currently developed Nautanen Cu-Au deposit. READ MORE
