Palaeobotanical Analysis of Certain Upper Ordovician Sedimentary Rocks Emphasizing Microfossil FragmentsThorne, William 10 1900 (has links)
Several methods for the palaeobotanical analysis of inorganic rocks are developed and through the employment of these methods both microfossils and macrofossils have been recovered from certain Upper Ordovician Strata. These fragments are assigned to series, basing such designation upon their sources and individual morphological characteristics. The problematical identity and biological importance of these fragments is discussed, and their practical usage in problems of correlation is considered. / Thesis / Master of Science (MSc)
