A rebuttal in Astronomy & Geophysics countered that Loeb et al. had ignored that the amount of iridium deposited around the globe, 2.0 × 10 8 –2.8 × 10 8 kg (4.4 × 10 8 –6.2 × 10 8 lb), was too large for a comet of the size implied by the crater, and that they had overestimated likely comet impact rates.
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
Location of the Boltysh crater. The Boltysh crater or Bovtyshka crater is a buried impact crater in the Kirovohrad Oblast of Ukraine, [1] near the village of Bovtyshka. The crater is 24 kilometres (15 mi) in diameter and its age of 65.39 ± 0.14/0.16 million years, based on argon-argon dating techniques, less than 1 million years younger than Chicxulub crater in Mexico and the Cretaceous ...
The volume of the crater is estimated as 230,000–250,000 cubic metres (8.1–8.8 million cubic feet), with a weight of about one million tons. The Patomskiy crater was described by Russian geologist Vadim Kolpakov in 1949, though it was known to the local population before this.
Chicxulub Pueblo Municipality is a municipality in the Mexican state of Yucatán containing (196.72 km 2) of land and located roughly 25 km north of the city of Mérida. [2] The area is directly onshore of the epicenter of the Chicxulub crater .
Chicxulub Puerto (IPA: [tʃikʃuˈlub] ⓘ) is a small coastal town in Progreso Municipality in the Mexican state of Yucatán. It is located on the Gulf of Mexico , in the northwestern region of the state about 8 km (5 mi) east of the city port of Progreso , the municipality seat, and 42 km (26 mi) north of the city of Mérida , the state capital.
The top of the melt sheet, which is the, "crater floor" and base of the post-impact sedimentary fill, ranges from 1.2 to 1.6 km below sea level as confirmed by drilling (Gulick et al. 2013:44). Interpretation of geophysical data indicates that the sedimentary fill on top of the melt sheet is as deep as 1.9 km (Gulick et al. 2013:44).
