Large complex impact craters form by collapse from initial excavation stage of a deep narrow bowl-shaped transient cavity. Fracturing and shattering of solids with finite tensile shear limits occur related to shock-induced damage of target material, with fracturing and fragmentation…

A structural model of the Chicxulub crater is derived from aeromagnetic anomaly modeling, borehole information and magnetic mineral data. Magnetic susceptibility measurements from borehole cores and samples in the crater show that suevite-like breccias have a variable strong magnetic signature,…

Active hydrothermal systems develop in impact structures formed in marine settings, associated with con-vective processes involving hydrothermal fuids and seawater. Here we investigate hydrothermal activity in the Chicxulub crater, which was formed by a large impact on the Yucatan carbonate…
