Meteorite Craters: Impact Phenomena

Scientific paper

Using Gauss's theorem, the authors estimate the mass deficiency of the Chicxulub impact structure (Yucatán, México) from its gravity anomaly. They estimate the equivalent total mass and volume of breccias and sedimentary rocks responsible for the gravity anomaly. These figures represent lower bounds on the mass and volume ejected from the impact crater. They represent estimates made from geophysical principles and data, and compare well with independent estimates based on other principles such as scaling relations. According to actual estimations of the sulfur dioxide mass generated by the Cretaceous-Tertiary impact, only a small fraction (about 1%) of the anhydrite in the target strata was vaporized.
