Those programs provided rock cores from the Chicxulub crater ring. Specifically, this study is based on about 15,000 kilograms (33,000 pounds) of rock retrieved from a bore-hole 1.3 km (0.8 miles


On the basis of the measured thickness of impact ejecta in Haiti and North America, the calculated volume of the impact melt sheet, and the chemical and isotopic composition of the melt sheet, the Chicxulub impact crater is inferred to be ∼180 km in diameter and to contain a ∼3 to 7 km thick melt sheet and breccia sequence within a centrally located ∼100 km diameter region that corresponds to the limits of the transient cavity.

Viewfield Crater Saskatchewan, Canada. Viewfield is an impact crater in Saskatchewan, Canada. It is 2.5 km in diameter and the age is estimated to be 190 ± 20 million years (Late Triassic). This belt is lying on the south margins of the borders of the impact crater, having its semicircular shape a radial distance of 90 km (180 km of diameter; which is the approximately distance from Celestun to Dzilam de Bravo), extending the crater itself its margins into the continental sea, at the same distance north. 19 Mar 2014 1 Introduction.

Själva kratern är begravd mer än 1 km under marken. Den beräknas vara ca 1,5 km djup med en diameter på 180 km. Vissa forskare hävdar att den är betydligt större än så, åtminstone 250 km i diameter.
