Abstract

A gravity profile, with 0.8 km station spacing, has been established along the Trans-Canada highway between Port-aux-Basques and Come-by-Chance, Newfoundland. A modified "one-base" barometric method gave improved elevation results, yielding a standard deviation which is less than one-half that associated with the traditional "one-base" method. Techniques have been devised to facilitate the determination of various model representation errors, and for making end corrections. A "winding-route" apparent anomaly effect has been studied. -- A qualitative profile interpretation has suggested the presence of unmapped gypsum deposits (south-western Newfoundland) and intrusive bodies (at several locations along the route). A detailed study between Notre Dame Junction and Traytown shows the Ackley batholith to be, in cross-section along the route, a funnel-shaped lopolith and this region to be underlain by an intermediate to basic layer.
