Only four tektite strewn-fields are known, and three of them are sourced from known impact craters. Here we show that the recently discovered Pantasma impact crater (14\u2009km diameter) in Nicaragua is the source of an impact glass strewn-field documented in Belize 530\u2009km away. Their cogenesis is documented by coincidental ages, at 804\u2009\u00b1\u20099\u2009ka, as well as consistent elemental compositions and isotopic ratios. The Belize impact glass share many characteristics with known tektites but also present several peculiar features. We propose that these glasses represent a previously unrecognized tektite strewn-field. These discoveries shed new light on the tektite formation process, which may be more common than previously claimed, as most known Pleistocene &gt;10\u2009km diameter cratering events have generated tektites.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pierre Rochette, Pierre Beck, Martin Bizzarro, R\u00e9gis Braucher, Jean Cornec, Vinciane Debaille, Bertrand Devouard, J\u00e9r\u00f4me Gattacceca, Fred Jourdan, Fabien Moustard, Fr\u00e9d\u00e9ric Moynier, S\u00e9bastien Nomade &amp; Bruno Reynard Communications Earth &amp; Environment, Volume 2, Article number:&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[90,3296],"tags":[944,4897,1955],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/27779"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=27779"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/27779\/revisions"}],"predecessor-version":[{"id":27780,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/27779\/revisions\/27780"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=27779"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=27779"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=27779"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
