The Chicxulub crater (IPA: [t͡ʃikʃuˈluɓ] ⓘ 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 location of the impact was unknown when the Alvarez team developed their hypothesis, but later scientists discovered the Chicxulub Crater in the Yucatán Peninsula, now considered the likely impact site. [4] Badlands near Drumheller, Alberta where erosion has exposed the K–Pg boundary.
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 ...
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.
The impact at the end of the Cretaceous Period gouged the Chicxulub (pronounced CHIK-shu-loob) crater, 112 miles (180 km) wide and 12 miles (20 km) deep. The clay layer is rich in metals including ...
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.
