New depositional environment for the Ile d'Orléans Group, Quebec Appalachians

Detailed logging of the sedimentary structure of the Cambro-Ordovician Île d’Orléans Group near Québec have permitted us to proposed a new interpretation of depositional setting of these sedimentary rocks. It is proposed that the Anse Maranda Formation, with its highly bioturbated mudstone and sandstone was probably deposited at the outer part of a continental shelf. The Lauzon Formation exhibits sedimentary facies like those of a fine-grained turbidite fan. The Pointe-de-la-Martinière Formation shows facies that most likely represent the upper continental slope with contourite and/or tempestite beds. 2001-D14 H. Longuépée and P.A.
