... metamorphism, affecting both the gneiss complex and Gander Lake Group, was associated with emplacement of megacrystic granite and extended from Devonian into early Carboniferous time. The Gander Lake Group may be time-equivalent to the Davidsville Group. There is no direct evidence either for or against...

... during or following oblique collision. Along the margin of the Gander Lake Subzone, the shear zone-hosted belt of sheeted granites and melting increasingly became the focus of deformation during the later stages of sinistral transpression. This suggests significant rheological softening of the crust...

... intruded by abundant mafic (now amphibolite) dykes ( Barr et al. 2002 ). Barr et al. ( 2002 ) proposed that the Kingston Group and related granite formed in an arc setting on the margin of the Exploits-Gander composite terrane (Fig.  1 , inset). The Pocologan metamorphic suite (Fig.  2 ) may represent...

.... The felsic rocks (originally rhyolites and dacites) were likely generated through partial melting of continental crust in response to intrusion of the mafic magma. Relatively low initial ε Nd values for both the mafic (−1.3 to +0.6) and felsic (−4.1 to −3.8) rocks suggest interactions with Gander zone...

... (Red Indian Lake arc) during the Late Ordovician (460–450 Ma). The Salinic orogeny was due to Late Ordovician–Early Silurian (450–423 Ma) closure of the Tetagouche–Exploits backarc basin, which separated the active leading edge of Ganderia from its trailing passive edge, the Gander margin. Salinic...
