Publisher's Synopsis
Excerpt from The Differentiation of a Secondary Magma Through Gravitative Adjustment
Dark-coloured red, brown and gray shales with thin intercalations of gray quartzite conformably overlie the Kitchener quartzite. The series, totalling 1050 meters in thickness, has been grouped under the name of the Moyie argillite. The formation appears but twice in the section and then only in comparatively small areas.
This great group of formations has been strongly dislocated in the building of the mountains. A few open folds broken by faults appear in the eastern half of the belt, but the deformation has been due in general to the tilting of monoclinal blocks separated by normal faults and, more rarely, by thrusts. The tilting of the beds ranges through all angles up to verticality, but the average dip is less than forty-five degrees. In consequence of the deformation and subsequent denudation the edges of more than 6600 meters of well-bedded ancient sediments are now exposed. There have also come to light a number of thick sills of gabbro intruded at various horizons into the Kitchener quartzite and the upper part of the Creston quartzite.
