La De\u00fbme (ou D\u00e9ome) est une rivi\u00e8re qui descend du Massif du Pilat et comme elle se doit elle transporte et d\u00e9pose des galets sur ses berges. Comment \u00e0 partir des observations des \u00e9chantillons r\u00e9colt\u00e9s, puis de leurs observations plus fines aux \u00e9chelles macroscopiques et microscopiques, nous avons pu d\u00e9crypter une partie de l\u2019histoire g\u00e9ologique r\u00e9gionale\u00a0?<\/p>

C\u2019est 10 personnes (8 adultes et 2 enfants) qui sont pr\u00e9sents pour cette d\u00e9couverte .<\/p>

Ces galets, r\u00e9colt\u00e9s, observ\u00e9s sur place \u00e0 l\u2019\u0153il nu et \u00e0 la loupe sont identifi\u00e9s ; ce sont des roches avec des origines diverses .<\/p>

Un atelier (situ\u00e9 \u00e0 l\u2019int\u00e9rieur de la Fnac situ\u00e9e \u00e0 proximit\u00e9) propose le microscope polarisant, des fiches de d\u00e9termination min\u00e9ralogique et quelques panneaux d\u2019informations sur les grandes cat\u00e9gories de roches, des cartes g\u00e9ologiques r\u00e9gionale et locale.<\/p>

Cette approche reconstitue quelques facettes du m\u00e9tier de g\u00e9ologue-chercheur d\u2019aujourd\u2019hui qui arpente les paysages de notre d\u00e9partement, r\u00e9colte des \u00e9chantillons, les analyse avec diff\u00e9rents outils techniques pour fournir une explication de leur pr\u00e9sence ici, et \u00e0 terme, reconstituer une histoire g\u00e9ologique qui s\u2019est d\u00e9roul\u00e9e dans notre r\u00e9gion sur plusieurs centaines de millions d\u2019ann\u00e9es.<\/p>
