<p> Geophysical studies of the northwest trending Sudbury olivine
diabase dikes, to the south of Coniston, Ontario establish a
deformation zone, within the Southern province up to 10 km from the
Grenville Front. Paleomagnetics reveal two directional groups
within the dikes; those with a NRM direction of 300°/32°
representing the primary magnetization of the dikes and those dikes
with a Grenville overprint direction of 116°/56°. The deviation in
direction of the two groups, in relation to previous studies
(Palmer et al., 1977) is interpreted to be due to fault block
movement. Aeromagnetics reveal extensive ductile and brittle
deformation in the dikes as they approach the front. The general
orientation of deformation is to the northeast. </p> / Thesis / Bachelor of Science (BSc)
