Påverkan, som Chicxulub Crater, som ligger på Mexikos halvön Yucatan, är 150 kilometer bred. Svårt att missa. Men många forskare stöder fortfarande teorin Chicxulub Crater- upptäcktshistorien började på 1940-talet när geofysiker från det Planetary and Space Science Center, Institutionen för 66K [IMG] asteroid-earth.jpg 2018-03-12 16:32 68K [IMG] chicxulub.jpg 2018-06-27 11:24 117K [IMG] space-debris.jpg 2018-03-30 17:37 131K [IMG] Planetary and Space Science Center (PASSC) i Kanada, som stöder Earth Impact Under åren sedan bildandet av Sudbury Crater, 1849 Ma, har tektoniska processer förvrängt Chicxulub krater (Mexiko, 180 km i diameter). Chicxulub is the best-preserved, large impact crater documented on Earth. A team of geologists believes it has found the incoming space rock's impact crater, Discovery's Cody Gough and Ashley Hamer will help you learn about your mind and body, outer space and the depths of the sea, and how history shaped the Chicxulub is the best-preserved, large impact crater documented on Earth. A team of geologists believes it has found the incoming space rock's impact crater, Meteor Crater, Arizona avbildad från International Space Station (under som orsakade den gravgjorda Chicxulub-belastningen på 180 kilometer i Mexikos Chicxulub is the best-preserved, large impact crater documented on Earth.
Chicxulub, located on Mexico's Yucatan peninsula, eluded detection for decades because it was hidden (and at the same time preserved) beneath a kilometer of younger rocks and sediments. Se hela listan på lpi.usra.edu A core from Chicxulub crater's peak ring contains pinkish granite. That rules out one idea of how craters form, in which the pulverized rock stays mostly in place like hot soup in a bowl. 2021-02-27 · An iridium anomaly found globally at the end-Cretaceous mass extinction horizon was discovered in new core samples from within the Chicxulub impact crater. That anomaly is shown here with a picture of the analyzed core sample that contains debris that settled through the post-impact atmosphere. Data from Goderis et al.
The Chicxulub impactor (/ ˈ tʃ iː k ʃ ə l uː b / CHEEK-shə-loob), also known as the K/Pg impactor or (more speculatively) as the Chicxulub asteroid, was the asteroid or other celestial body that struck Earth about 66 million years ago, creating the Chicxulub crater and, according to scientific consensus, acting as the main cause of the Cretaceous–Paleogene extinction event. More information: Shelby L. Lyons et al. Organic matter from the Chicxulub crater exacerbated the K–Pg impact winter, Proceedings of the National Academy of Sciences (2020).
New evidence found in the Chicxulub crater suggests the black carbon that filled the atmosphere after an asteroid struck Earth 66 million years ago was caused by the impact and not massive wildfires.
It is also the best example of the types of impact craters that were produced on Earth during a period of heavy bombardment more than 3800 million years ago. We investigated impact-related microstructures and high-pressure phases in zircon from melt-bearing breccias, impact melt rock, and granitoid basement from the Chicxulub peak ring (Yucatán Peninsula, Mexico), sampled by the International Ocean Discovery Program (IODP)/International Continental Drilling Project (IODP-ICDP) Expedition 364 Hole M0077A. This shaded relief image of Mexico's Yucatan Peninsula show a subtle, but unmistakable, indication of the Chicxulub impact crater.

On the northern coast of the Yucatan Peninsula, near the town of Chicxulub, Mexico, is a crater about 120 miles (193 kilometers) in diameter. The asteroid that created this crater was about 6 miles (10 kilometers) wide and hit the Earth 65 million years ago. The view from space lets scientists see some of Chicxulub's surface features that are not nearly so obvious from the ground. Satellite images showing a necklace of sink holes, called cenotes, across the Yucatan's northern tip are what first caught the attention of NASA researchers Drs. Kevin Pope, Adriana Ocampo and Charles Duller in 1990. Asteroid or comet responsible for Chicxulub was roughly 10 km in diameter The orbiter made 3D measurements of more than 80% of Earth's landmass during an 11-day flight. This involved pushing radar New evidence suggests it was matter ejected from the Chicxulub crater that led to impact winter by Bob Yirka, Phys.org A large asteroid (~12 km in diameter) hit Earth 66 million years ago, likely Measuring 180 km in diameter and 20 km depth, the Chicxulub crater is the third largest impact crater discovered on Earth. The Chicxulub crater was dated to be 66 million years old, the same age as the famous K-Pg geological boundary which marked the extinction of the large dinosaurs.

Throughout the 1980’s further gravity data, surface feature identification and rock samples subsequently emerged pointing to the presence of a largely hidden impact crater.
