Abstract
The gravity map of the Nabesna quadrangle indicates significant variations in the densities and thicknesses of the rock units that underlie the quadrangle. Most of this gravity relief is indirectly related to regional topographic relief or lithologic variations that are revealed in the rock outcrops. However, some significant features of the gravity map are not easily explained by the map geology, and several important features on the geologic map seem to have little gravitational expression. These failures in correlation suggest that there may be considerable differences between the deep and shallow structures of the quadrangle. Understanding these differences may eventually alter the present estimates of the quadrangle's mineral potential.
