| dc.description.abstract | In this project we gathered and interpreted gravity anomaly data at Meteor Crater, and we used these data to constrain the porosity variations across Meteor Crater that were induced by the crater-forming impact event. We performed a gravity survey at the crater and merged these new data with legacy gravity survey data. From the resulting merged gravity data set, we generated a reduced anomaly map and created a model to estimate the gravitational effects of several stratigraphic units across Meteor Crater. Finally, we used a Bayesian inversion scheme to infer the bulk density and porosity of each stratigraphic unit. The models reflect the creation of impact-induced porosity of ~5-10% around and beneath the crater, supporting previous findings with novel methods and data. | |
