Due to the unique location of the Quebec Appalachians in a re-entrant of the paleo-North
American margin and to the fact that the area largely escaped late Paleozoic deformation …

Abstract During the Early to Middle Palaeozoic, prior to formation of Pangaea, the Canadian
and adjacent New England Appalachians evolved as an accretionary orogen. Episodic …

This paper presents new ideas on the Early Palaeozoic geography and tectonic history of
the Iapetus Ocean involved in the formation of the northern Appalachian-British Caledonide …

The Ammonoosuc Volcanics, Partridge Formation, and the Oliverian and Highlandcroft
Plutonic Suites of the Bronson Hill anticlinorium (BHA) in axial New England are widely …

We integrate new and existing age data from ophiolite and subophiolite rocks in the Thetford
Mines region, Québec Appalachians, to determine the timing of:(1) oceanic crust …

The∼ 5 km thick mantle of the Ordovician Thetford Mines Ophiolite is dominated by
harzburgite (≤ 5–6% clinopyroxene), cut by dunitic to orthopyroxenitic dykes. The plutonic …

A combination of deep seismic imaging and drilling has demonstrated that the ocean-
continent transition (OCT) of present-day, magma-poor, rifted continental margins is a zone …

The seabed of the St. Lawrence Estuary is characterized by many fluid releasing features.
On multibeam bathymetric images these features correspond to crater-like depression …

This study presents the results of the reprocessing and geological reinterpretation of a trio of
regional seismic reflection lines acquired by the Ministère des Ressources naturelles du …

Abstract In the Quebec Appalachians, the St-Joseph fault is a major normal fault that mostly
juxtaposes metamorphic remnants of the Laurentian margin in its footwall and the adjacent …
