It spans about 1.85 kilometres. Thus, it&#8217;s the biggest crater on Earth which is under 100,000 years old. Geological dating sediments suggests that this crater was formed between 46,000 and 53,000 years ago.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/scitechdaily.com\/images\/Yilan-Crater-Annotated.jpg\" alt=\"Young Impact Crater Uncovered in Yilan, China\" \/><\/p>\n<p>Meteor or Barringer Crater Meteor or Barringer crater in Arizona is additionally around 50,000 years old.

They found many meters of ancient lake sediments and shattered granite.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/cdn.mos.cms.futurecdn.net\/JVBZtYDmxUvni5xW9TDtga-1200-80.jpg\" alt=\"Scientists uncover the largest crater on Earth under 100,000 years old | Live Science\" \/><\/p>\n<p>They also found unambiguous evidence that the structure was indeed an effect crater. A quartz, glass containing holes formed by gas bubbles, melted granite and tear-drop shaped glass fragments were found by the team . These factors indicate a high-intensity impact event. Presence of lakebed sediments inside this crater highlights that the rim was intact long enough for a significant deposit increase on the bottom. Such deposits produce rich organic soil.<\/p>\n<p>Yilan crater is a sway crater in China.
