Gravity measurements in the vicinity of Georges Bank
A total of 97 new bottom gravity measurements on the continental shelf in the vicinity of Georges Bank was reduced to the simple Bouguer anomaly, using a density of 2.80 gm per cm 3 for the correction. Results help substantiate the presence of mafic and felsic intrusive bodies along the northern edge of the bank. A gravity low near the center of the bank, trending northeast, corresponds to the Georges Bank trough. An abrupt change in the gravity gradient near the southeast edge of the bank probably represents the thinning of the crust from continental to oceanic thicknesses. Differences in gravity gradient support the suggestion of a fault along the northern edge of the bank.
