The Chicxulub crater (Spanish: [t͡ʃikʃuˈlub] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo (not the larger coastal town of Chicxulub Puerto ). [ 3 ]
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. [10] Its center is located near the town of Chicxulub, after which the crater is named. [11] It was formed by a large asteroid or comet about 10–15 km (6.2–9.3 mi) in diameter, [12] [13] the Chicxulub impactor, striking the Earth. The date of the ...
However, in 1991, scientists found that the Chicxulub crater was the right age to have been formed by a massive asteroid strike coinciding with the demise of the dinosaurs. Over the years ...
Evidence at the Chicxulub crater supports the notion that the crash would have been devastating enough to send deadly vaporized rock and gas into the atmosphere, filling the Earth with dust ...
Shocked quartz was discovered following underground nuclear weapons testing, which generated the intense pressures required to alter the quartz lattice. Eugene Shoemaker showed that shocked quartz is also found inside craters created by meteor impact, such as the Barringer Crater and Chicxulub crater. [1]
Further research identified the giant Chicxulub crater, buried under Chicxulub on the coast of Yucatán, as the source of the K–Pg boundary clay. Identified in 1990 [14] based on work by geophysicist Glen Penfield in 1978, the crater is oval, with an average diameter of roughly 180 km (110 mi), about the size calculated by the Alvarez team.
Chicxulub Pueblo (Mayan pronunciation: [tʃʼikʃuluɓ] Ch’ik Xulub) is a town, and surrounding municipality of the same name, in the Mexican state of Yucatán. At the census of 2010, the town had a population of 4,080 people. The center of the Chicxulub Impact Crater (approx 21°20'N 89°30'W) is off the Yucatan coast, near Chicxulub Puerto
