Dimensional Grain Orientation of Ordovician Turbidite GreywackesOnions, Diane 10 1900 (has links)
This study describes the analysis of orientation of elongate quartz grains in turbidite greywackes of the Normanskill Formation, (Ord.) New York.
No relationship is found between grain orientation and sole features of the beds. No relationship exists between grain orientations taken at different levels above the base of the beds.
Maximum grain size and maximum elongation decrease upwards in the beds. The most elongate grains are those which most clearly show preferred orientation. / Thesis / Master of Science (MSc)

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)
