Kwixesha elidlulileyo, iifestile zemache zephepha zazisetyenziswa kwiChina yamandulo, kwaye iifestile zeglasi zifumaneka kuphela kumaxesha anamhlanje, okwenza iindonga zeglasi zamakhethini ezidolophini zibe ngumbono omangalisayo, kodwa amashumi amawaka eminyaka ubudala iglasi nayo yafunyanwa emhlabeni, kanye Ipaseji yeekhilomitha ezingama-75 kwiNtlango ye-Atacama kumantla elizwe laseMzantsi Melika laseChile.Iidiphozithi zeglasi emnyama ye-silicate zisasazekile ekuhlaleni, kwaye ziye zavavanywa ukuba zilapha iminyaka eyi-12,000, ngaphambi kokuba abantu benze itekhnoloji yokwenza iglasi.Kubekho uqikelelo lokuba zivela phi ezi zinto ziglasi, njengoko kuphela ukutsha kobushushu obuphezulu kakhulu bekunokutshisa umhlaba wesanti ukuba ube ziikristale zesilicate, ke abanye bathi "isihogo somlilo" sakha sabakho apha.Uphononongo lwakutsha nje olukhokelwa yiDyunivesithi yaseBrown yeSebe loMhlaba, iNzululwazi yeNdalo kunye nePlanethi icebisa ukuba iglasi inokuba yenziwe ngubushushu obukhawulezayo becomet yakudala eyaqhuma ngaphezulu komhlaba, ngokutsho kwengxelo kaNov. 5 Yahoo News.Ngamanye amazwi, imfihlelo yemvelaphi yezi glasi zamandulo iye yasonjululwa.
Kuphononongo lweDyunivesithi yaseBrown, esanda kupapashwa kwijenali yeGeology, abaphandi bathi iisampulu zeglasi yasentlango ziqulathe amaqhekeza amancinci angafumanekiyo eMhlabeni ngoku.Kwaye iiminerali zihambelana ngokusondeleyo nokubunjwa kwezinto ezibuyiselwe eMhlabeni yi-NASA ye-Stardust mission, eqokelele amasuntswana kwi-comet ebizwa ngokuba yi-Wild 2. Iqela lidityaniswe nezinye izifundo ukugqiba ukuba ezi ngqungquthela zamaminerali zinokwenzeka ukuba ziziphumo ze-comet kunye nokwakheka. efana ne-Wild 2 eyaqhuma kwindawo ekufutshane noMhlaba kwaye ngokuyinxenye kwaye ngokukhawuleza yawela kwiNtlango ye-Atacama, ngoko nangoko ivelisa amaqondo obushushu aphezulu kakhulu kunye nokunyibilika komhlaba onesanti, ngelixa ishiya ngasemva ezinye zezinto zayo.
Le mizimba yeglasi igxile kwiNtlango ye-Atacama kwimpuma yeChile, ithafa elikumantla eChile kumda weAndes ngasempuma kunye noNxweme lwaseChile ngasentshona.Ekubeni kungekho bungqina bogqabhuko-dubulo lwentaba-mlilo olunobundlobongela apha, igenesis yeglasi ibisoloko itsala igeological and geophysical community ukwenza uphando lwasekhaya olufanelekileyo.
Ezi zinto zeglasi ziqulethe i-zircon component, ethi i-therrmally idibanise ukwenza i-baddeleyite, ukuguqulwa kwamaminerali okufuna ukufikelela kumaqondo okushisa angaphezu kwe-1600 degrees, okungekho mlilo wasemhlabeni.Kwaye ngeli xesha uphononongo lweDyunivesithi yaseBrown luye lwachonga ngakumbi imidibaniso ekhethekileyo yeeminerali ezifumaneka kuphela kwiimeteorites kunye namanye amatye angaphandle komhlaba, njengecalcite, i-meteoric iron sulfide kunye ne-calcium-aluminium-rich-rich inclusions, ehambelana nesiginitsha yemineralogical yeesampulu zecomet ezithathwe kwi-NASA's Stardust mission. .Oku kwakhokelela kwisigqibo esikhoyo ngoku.
