The round-shaped crater, with a diameter of 3.6 kilometers and borders that rise up to 125 meters above the central swampy plain, was accidentally discovered in 1961 through aerial photographs. The crater possibly resulted from the impact of a fairly big meteorite, or from some other heavenly body that has not been identified yet. Analyses of the rocks and sediments have not elucidated the origin of the crater; however, they indicated that the crater must have been formed at least 2.5 million years ago. Now, it can be stated that the layer of sediment probably goes down to a depth of 275 meters; previous estimates had measured the depth as ranging from 285 to 400 meters. The researchers noticed that a crater in China, described in 2011, was geologically similar to the Colonia crater, although the Chinese crater\u2019s diameter measured only 1.8 kilometers. Geologists believe that these and other craters could contain materials or remains that might provide a better understanding of changes that occurred on the planet during the geological period referred to as the Quaternary Period, when the Earth went through intense climate change.<\/p>\n","protected":false},"excerpt":{"rendered":"Detailed description of geological formation is put together","protected":false},"author":6,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[168],"tags":[240],"coauthors":[785],"class_list":["post-43796","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-geology"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/43796","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=43796"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/43796\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=43796"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=43796"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=43796"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=43796"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
