BUL 051

Petrology and geochemistry of the Canadian Shield of northeastern Alberta

The remnant, central belt of granodioritic to quartz-monzonitic gneiss, of I-type granitoid composition, is flanked on its western argin by fairly homogeneous protons of biotite quartz monzonite to granite (Slave and Arch Lake Granitoids), and on ... Show Abstract

Geology of the basement beneath the Athabasca Basin in Alberta

The basement beneath the unconformity can be subdivided into four granitoid rock types recognized as part of the Wylie Lake pluton, and two mylonitic rock types derived partly from the granitoids and partly from a metasedimentary or metavolcanic ... Show Abstract

Polyphase Deformation in the Canadian Shield of Northeastern Alberta

Two generations of structures can be distinguished in the granite gneisses and intercalated high-grade metasediments of the basement neiss complex, which has been shown to be Archean by radiometry dating. In some areas, D2 folds form parts of domes ... Show Abstract
