However, the recent field mapping has shown that the two plutons are separated by a screen of sedimentary rocks from 300 to 400 m wide and so do not come into direct contact with one another as shown on earlier maps; thus, the Magaguadavic pluton in this area intruded sedimentary and volcanic rocks along its eastern margin--Ordovician quartzose sandstone of the Kendall Mountain Formation (Cookson Group) in the north and Silurian siltstone and mafic volcanic tuff assigned to the Jones Creek Formation (Mascarene Group) in the south--and the Mount Douglas pluton intruded the same screen of sedimentary and volcanic rocks of Jones Creek Formation along its western margin (Fig.
