This leaves scientists to wonder, how  and where to all the xenon vanished in the mean time. David S. Brock and  Gary J. Scholbrick, chemists from McMaster Universtity in Hamilton,  Canada, now shed light on this mystery. Obtaining Xe(IV) oxide by  hydrolysis of Xe(IV) fluoride allowed Brock and Scholbrick to obtain  detailed Raman spectra of Xe<sup>18<\/sup>O<sub>2<\/sub> and Xe<sup>18<\/sup>O<sub>2<\/sub>. Suprisingly, these  spectra are in line with earlier studies of xenon doped siliciumdioxide,  which is the most plentiful mineral in the earth&#8217;s crust. Thus, all the  xenon in the earth&#8217;s atmosphere might have vanished by being inserted  into SiO<sub>2<\/sub> minerals under extreme conditions.<\/p>\n<p>Read more:<\/p>\n<p><a href=\" http:\/\/pubs.acs.org\/doi\/abs\/10.1021\/ja110618g \"><\/p>\n<p>http:\/\/pubs.acs.org\/doi\/abs\/10.1021\/ja110618g <\/a><\/p>\n<p><a href=\" http:\/\/www.nature.com\/nature\/journal\/v471\/n7337\/full\/471138d.html \"><\/p>\n<p>http:\/\/www.nature.com\/nature\/journal\/v471\/n7337\/full\/471138d.html <\/a><\/p>\n<p>The <a href=\"http:\/\/de.wikipedia.org\/w\/index.php?title=Datei:QuarzGeruest_a1-a2-Ebene.svg&amp;filetimestamp=20100107224854\">picture<\/a> shows the general structure of tetrahedral siliciumdioxide<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Of all the gaseous xenon the earth&#8217;s primordial atmosphere contained, only roughly 10 % is left today.
