Analogue model of rift linkage and inversion with application to the Western Alps

Along-strike segmentation of orogens raises questions because its causes may predate orogeny in relation to structural inheritance. Here we focus on rift/margin linkage domains and their inversion by using analogue models with image analysis to extract the 3D strain field. Extensional models document, depending on the strike-perpendicular offset and the brittle-crust thickness, three types of rift linkage modes: (1) oblique linkage with early T-fault, (2) strongly-oblique linkage with R-fault network and, (3) transfer-linkage with late Y-strike-slip fault. Analogue model of inverted rift basins is used to analyse the misunderstood tectonic evolution of transition zones in the segmented Western Alpine belt

Valoriser les productions locales: Enchevêtrement de démarches ou multi-inscription raisonnée ?

International audienceThe local anchoring of food products is nowadays claimed in many ways. How is this multiplicity of positions apprehended from the point of view of producers, since it is largely they who implement it? Based on two field studies in the former Midi-Pyrénées region, we show how the multi-inclusion of producers in value-adding processes is more structured than it seems, based in particular on a differentiation between a peasant ethic of production and a heritage ethic of production.L’ancrage local des produits alimentaires est aujourd’hui revendiqué de multiples manières. Comment cette multiplicité est-elle appréhendée du point de vue des producteurs ? À partir de deux terrains en Midi-Pyrénées, nous montrons en quoi la multi-inscription des producteurs dans des démarches de valorisation connaît une structuration plus aboutie qu’il n’y paraît, reposant notamment sur une différenciation entre une éthique de production paysanne et une éthique de production patrimoniale
