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

BUL 045

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

BUL 042

Polyphase Metamorphism in the Canadian Shield of Northeastern Alberta

During the Archean metamorphic cycle, metasediments were metamorphosed under high pressure granulite conditions (M1). Coexisting garnet-biotite and garnet-cordierite pairs in the metasediments allows estimation of P-T conditions during the ... Show Abstract

Geophysical expression of the Canadian Shield of northeastern Alberta

The Canadian Shield of northeastern Alberta has a geophysical expression controlled by lithology and complex structural- metamorphic features. The magnetic field of the Alberta Shield (the exposed part of the Canadian Shield in Alberta) shows a ... Show Abstract
