Abstract
Abstracts of Theses: Statistical Examination of Gravity Anomalies Over Preglaciated Terrains
The statistical analysis of gravity data over the central part of the Canadian Shield and the compilation of free-air anomaly and isostatic anomaly maps, were carried out in an attempt to reveal crustal depression due to ice loading during the last glaciation period. Increasingly negative free-air anomalies towards Hudson Bay reach a value of about -30 mgal and suggest a present crustal depression of about 215 metres. The mean of the free-air anomalies over the entire region is about -16 mgal which indicates that the whole region is overcompensated.
