The pre-Jurassic tectonic events of the area controlled
the nature of sedimentation. These tectonic events were the
result of movements of the members of the tectonic framework.
The nature of the tectonic framework was established during
Beltian sedimentation and was inherited by the Paleozoic era.
During the Paleozoic era, the movements of various members of the
tectonic framework resulted in four sequences or cycles of sedimentation.
Tectonism and its control upon sedimentation from
Beltian to pre-Jurassic time is shown as Beltian sedimentation
and the succeeding sedimentary cycles are discussed. Type localities
are defined for the Beltian and Paleozoic strata of each
sequence as they occur in the area. Problems of age determination
for the stratigraphic units are discussed and the correlation
of these units within and beyond the are presented. These
correlations show the relationship of the stratigraphic nomenclature
of Montana and Alberta.
Since the thesis is mainly limited to published
information, it indicates the present status of published
geological thought in the area. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
