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 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

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

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

Geology of the Athabasca Group in Alberta

The Wolverine Point Formation is informally subdivided into an upper and a lower member.Petrographic studies of the Athabasca Group support the formational divisions and reveal a complex history of diagenesis. The diagenesis affected the porous ... 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

Geology of the Bayonet, Ashton, Potts and Charles Lakes Districts, Alberta

The geology of 308.5 square miles of Precambrian Shield in northeastern Alberta is presented on six colored maps of scale 2 inches to 1 mile. Biotite granite is petrologically distinct and unique in its close association with certain ... Show Abstract

Geology of the Andrew Lake, South District, Alberta

The geology of a 72 square-mile area in the Precambrian Shield of northeastern Alberta is shown on a colored map of a scale of 2 inches to 1 mile. The western part of the area is underlain by granite gneiss containing isolated bands and patches of ... Show Abstract
