Plant microfossils are extracted from strata of Upper Devonian
age occurring at two previously uninvestigated localities in Eastern
Canada and in the Canadian Arctic. The extraction procedure includes
a new permanent palynological mounting technique using corn syrup and Permount, a synthetic resin. In addition, a method of eliminating by-product in residues after hydrofluoric acid, is also described. A number of miospore and acritarch form species are described
and figured; nine new form species of miospores are proposed. The
miospore species recovered from both localities indicate a geological
age of early Upper Devonian (Frasnian) for the enclosing strata. A new way of assessing qualitative, regional palaeofloristic
changes is provided by tabulation of morphological characteristics of
individual miospores. The use of miospore species in defining Upper
Devonian microfloral provinces and Upper Devonian-Lower Carboniferous migration of parent forms is demonstrated. / Thesis / Master of Science (MSc)
