The Chicxulub Crater . The … The discovery of shocked quartz, shocked feldspar, and impact melts in the Yucatán-6 exploration borehole from the interior of the Chicxulub structure, proved it was an impact crater and that it was produced at the Cretaceous-Tertiary (K-T) boundary. The immense Chicxulub crater is a remnant of one of the most consequential days in the history of life on Earth. The Chicxulub Crater, named after the village which lies near its center, spans over 110 miles wide, with about half of it resting below the Gulf of Mexico. This is a radar image of the southwest portion of the buried Chicxulub impact crater in the Yucatan Peninsula, Mexico. It was identified from a nearly circular gravity anomaly along the northwestern edge of the Yucatán Peninsula (Figure 1). The buried structure, which measures at least 180 km (112 miles) across, is thought to be the scar remaining from the impact 66 million years ago of an asteroid or comet … With a force of 100 million megatons of TNT (two million … Molten debris rebounded into the air and crashed back into the crater, causing massive waves of lava to surge outward … Chicxulub crater in Mexico, Yucatan Peninsula, was formed as a result of a meteorite crush about 65 million years ago. The radar image was acquired on orbit 81 of space shuttle Endeavour on April 14, 1994 by the Spaceborne Imaging Radar C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR). In the Chicxulub crater, though, hundreds of feet of sediments built up rapidly, recording impact effects like a high-speed stop-action camera, the scientists said. Hildebrand, A., Pilkington, M., Connors, M. et al. The Chicxulub asteroid was 9 miles wide and changed the course of life on Earth dramatically. 2,3 There’s disagreement on the crater’s exact size, but its diameter is approximately … The Chicxulub crater isn’t visible on the surface because it is covered by younger, relatively undeformed sediments. Chicxulub Impact Breccia. Some 65 million years ago, an asteroid or comet the size of a small city came hurtling toward Earth. Later investigations suggested that this impact structure is dated from the late Cretaceous, about 65 million years ago. Chicxulub Crater is an ancient impact crater buried underneath the Yucatan peninsula, with its center located approximately underneath the town of Chicxulub, Yucatán, Mexico. Here's what we've learned from the Chicxulub Crater samples: The initial asteroid impact blasted a hole in the Earth approximately 30 miles deep and filled with molten rock and super-heated steam. Size and structure of the Chicxulub crater revealed by horizontal gravity gradients and … According to scientists, this catastrophe could have been the cause of the partial or complete extinction of dinosaurs. The asteroid strike triggered the Cretaceous-Paleogene, or K-Pg, mass extinction. Chicxulub crater on the northern coast of the Yucatán Peninsula in Mexico, in a computer-generated image synthesized from gravity and magnetic-field data. Chicxulub is quite young in comparison with other large craters of our planet.
