Gravity data have been used to calculate the mass deficiency and hence the amount of shattered rock under the Deep Bay, Brent, and Holleford craters. The results show good agreement with the crater model computed by Rottenberg as combined with the depth/diameter ratios of Baldwin for meteorite impact craters. The zone of complete rupture is shown to extend to a depth of approximately one-third of the crater's diameter, and impact energy values, derived from energy of crushing, are 6.5×1023 ergs… CONTINUE READING
