摘要

Small negative gravity anomalies are found in gravity data from along the northwestern shoreline of the Yucatan Peninsula These anomalies are shown to be due to elongate, shallow anomalous porosity zones in-the Tertiary carbonates. These zones are caused primarily by groundwater solution and are presently active conduits for groundwater flow. The association of these small gravity anomalies with known topographic and structural features of the area, which partially overlies the Chicxulub Impact crater, indicates their development was influenced by structures, faults and/or fractures, within the Tertiary and pre-Tertiary carbonates.
