| Abstract | Anorthosite has been discovered at the margin of the M'Clure Bay granite, a large rapakivi granite intrusion (1703 Ma old) in northwestem Somerset Island. It appears to form a sheet, 20 m thick, and is
probably cogenetic with the granite. Substantial sequences of the Proterozoic Aston Formation lie nonconformably on basement adjacent to the Paleozoic terranes on eastem Prince of Wales Island and Prescott and Pandora islands. A representative
section measured on Prince of Wales Island comprises 700 m of shallow-marine rocks: a thin breccia-conglomerate resting on gneiss, 200 m of reddish arkose, and a 500 m-thick succession mainly of more mature quartz sandstone. A 200 m-thick gabbro sill
(1268 Ma) has intruded the section. The section terminates at the high-angle reverse fault juxtaposing Proterozoic and Paleozoic strata at the margin of the Boothia Uplift. The intense deformation evident in rocks on both sides of the fault is
consistent with a compressive tectonic regime. |
