The Chicxulub crater in Mexico 2, 3, 4, 5, 6, 7, which is the largest known Phanerozoic impact structure, is now widely accepted as the site of this event. The crater is located partly offshore;


Krateren själv är begravd under Yucat-n-halvön och bildades genom inverkan av en stor asteroid runt 10-15 kilometer i diameter. Datumet för denna inverkan 

The Chicxulub impact crater, which is the principal source of impact debris in Cretaceous‐Tertiary boundary sediments, is currently buried by a ∼1 km thick sequence of carbonate sediments. Because the crater is not exposed for direct scrutiny, its size has remained uncertain, and in particular, estimates ranging from ∼100 to ∼300 km have been made on the basis of gravity and magnetic 2020-11-07 The Chicxulub Crater was 150 kilometer wide in diameter.

2,3 There’s disagreement on the crater’s exact size, but its diameter is approximately 110 miles The ~180-km-diameter Chicxulub peak-ring crater and ~240-km multiring basin, produced by the impact that terminated the Cretaceous, is the largest remaining intact impact basin on Earth. International Ocean Discovery Program (IODP) and International Continental Scientific Drilling Program (ICDP) Expedition 364 drilled to a depth of 1335 m below the sea floor into the peak ring, providing a After examining the crater size, the meteoritic content for mass, and the impact models for velocity, researchers find indications to believe that the Chicxulub crater was formed by a short period comet or an asteroid impact that released 0.7-3.4 × 10 31 ergs of energy. [3] One of the greatest scars on our planet is hidden beneath the Yucatán Peninsula and the Gulf of Mexico. The buried crater, over 90 miles in diameter, was created when a massive asteroid struck the Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. It was formed when a large asteroid or comet about 11 to 81 km. in diameter, known as the Chicxulub impactor, struck the Earth 66 million years ago. 35 views · Answer requested by The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico.

With regards to the Siljan impact structure, the pre-erosional rim-to-rim diameter of the crater was estimated to be on the order of 60 km, based on a combination of shock barometry and numerical simulation, produced by a collision between a ~5 km diameter projectile and Earth.

The crater is over 180 km (110 miles) in diameter, located next to the village of Chicxulub in Yucatan.
