Ngaphambili, iifestile zemache zephepha zazisetyenziswa eTshayina yamandulo kwaye iifestile zeglasi zezanamhlanje kuphela, nto leyo eyenza iindonga zeglasi zezixeko zibe ngumbono omangalisayo, kodwa amashumi amawaka eminyaka ubudala iglasi iye yafunyanwa emhlabeni, kanye kwipaseji yeekhilomitha ezingama-75. kwiNtlango yeAtacama kumantla elizwe loMzantsi Merika eChile.Iidiphozithi zeglasi emnyama ye-silicate zithe saa kule ndawo kwaye ziye zavavanywa ukubonisa ukuba zikhona iminyaka eyi-12,000, ngaphambi kokuba abantu benze itekhnoloji yokwenza iglasi.Kubekho uqikelelo lokuba zivela phi ezi zinto zeglasi, njengoko kuphela ukutshisa okutshisa kakhulu bekunokutshisa umhlaba oyisanti kwiikristale ze-silicate, okukhokelela abanye ukuba bacebise ukuba "isihogo somlilo" senzeke apha.Uphononongo lwakutsha nje olukhokelwa yi-Brown University yeSebe loMhlaba, i-Environmental and Planetary Sciences lubonisa ukuba iglasi inokuba yenziwe ngokutshisa ngokukhawuleza kwe-comet yamandulo eyaqhuma ngaphezu komhlaba, ngokutsho kwengxelo ye-Yahoo News ngo-5 Novemba.Ngamanye amazwi, imfihlelo yemvelaphi yeglasi yakudala isonjululwe.
Kuphononongo lweDyunivesithi yaseBrown, esanda kupapashwa kwijenali yeGeology, abaphandi bathi iisampulu zeglasi yasentlango zinezinto ezincinci ezingafumanekiyo eMhlabeni ngoku.Kwaye iiminerali zihambelana ngokusondeleyo nokwakhiwa kwezinto ezibuyiselwe eMhlabeni yi-NASA ye-Stardust mission, eqokelele amasuntswana kwi-comet ebizwa ngokuba yi-Wild 2. Iqela laphetha, ngokubambisana nezinye izifundo, ukuba ezi ndibano zeminerali zinokuba sisiphumo se i-comet enesakhiwo esifana ne-Wild 2 eqhuma kwindawo ekufutshane noMhlaba, kunye neenxalenye eziwela ngokukhawuleza 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 yeAtacama kwimpuma yeChile, ithafa elikumntla weChile elimkelwe ziiAndes ngasempuma neeNtaba zoNxweme lwaseChile ngasentshona.Ukungabikho kobungqina bogqabhuko-dubulo lwentaba-mlilo enobundlobongela, igenesis yeglasi ibisoloko itsala igeological and geophysical community kwingingqi ukwenzela uphando olunxulumeneyo.
