Esikhathini esidlule, amafasitela e-paper mache ayesetshenziswa eChina lasendulo, futhi amafasitela engilazi atholakala ezikhathini zanamuhla kuphela, okwenza izindonga zamakhethini ezingilazi emadolobheni zibe umbono omuhle kakhulu, kodwa ingilazi yeminyaka eyizinkulungwane eziyishumi nayo iye yatholakala emhlabeni, khona kanye umhubhe ongamakhilomitha angama-75 woGwadule lwase-Atacama engxenyeni esenyakatho yezwe laseNingizimu Melika eChile.Idiphozithi yengilazi ye-silicate emnyama ihlakazekile endaweni, futhi ihlolwe ukuthi ibe lapha iminyaka eyi-12,000, ngaphambi kokuba abantu basungule ubuchwepheshe bokwenza ingilazi.Kube nokuqagela ukuthi lezi zinto eziyingilazi zivelaphi, njengoba ukushisa okuphezulu kakhulu kuphela obekungashisa inhlabathi eyisihlabathi ibe amakristalu e-silicate, ngakho abanye bathi “isihogo somlilo” kwake kwenzeka lapha.Ucwaningo lwakamuva oluholwa uMnyango wezeNyuvesi yaseBrown, i-Environmental and Planetary Sciences luphakamisa ukuthi kungenzeka ukuthi ingilazi yakhiwe ukushisa okuphazima kweso kwenkanyezi enomsila yasendulo eyaqhuma ngaphezu komhlaba, ngokombiko we-Yahoo News wango-Nov. 5.Ngamanye amazwi, imfihlakalo yemvelaphi yalezi zibuko zasendulo isixazululiwe.
Ocwaningweni lwaseBrown University, olusanda kushicilelwa kuphephabhuku iGeology, abacwaningi bathi amasampula engilazi yasogwadule aqukethe izingcezu ezincane ezingatholakali eMhlabeni njengamanje.Futhi amaminerali ahambisana eduze nokwakheka kwezinto ezibuyiswe eMhlabeni umkhankaso we-NASA we-Stardust, owaqoqa izinhlayiya zenkanyezi enomsila ebizwa ngokuthi i-Wild 2. Ithimba lahlanganiswa nezinye izifundo ukuze liphethe ngokuthi lezi zinhlanganisela zamaminerali cishe ziwumphumela wenkanyezi enomsila efana ne-Wild 2 eyaqhuma endaweni eseduze noMhlaba futhi kancane kancane yawela oGwadule Lwase-Atacama, yakhiqiza ngokushesha amazinga okushisa aphakeme kakhulu futhi yancibilikisa indawo enesihlabathi, kuyilapho ishiya ezinye zezinto zayo.
Lezi zindikimba eziyingilazi zigxile oGwadule Lwase-Atacama empumalanga yeChile, ithafa elisenyakatho yeChile elizungezwe izintaba zase-Andes ngasempumalanga kanye neChilean Coastal Range ngasentshonalanga.Njengoba kungekho bufakazi bokuqhuma kwentaba-mlilo okunodlame lapha, i-genesis yengilazi ihlale iheha umphakathi we-geological and geophysical ukwenza uphenyo lwasendaweni olufanele.
Lezi zinto eziyingilazi ziqukethe ingxenye ye-zircon, ebuye ibole ngokushisa ukuze yakhe i-baddeleyite, ukuguqulwa kwamaminerali okudinga ukufinyelela emazingeni okushisa angaphezu kuka-1600 degrees, okungewona ngempela umlilo wasemhlabeni.Futhi kulokhu ucwaningo lweNyuvesi yaseBrown seluphinde lwahlonza inhlanganisela eyinqaba yamaminerali atholakala kuphela kuma-meteorite namanye amadwala angaphandle komhlaba, njenge-calcite, i-meteoric iron sulfide kanye ne-calcium-aluminium-rich-rich inclusions, okuhambisana nesiginesha ye-mineralogical yamasampula enkanyezi enomsila athathwe kumishini ye-Stardust ye-NASA. .Lokhu kwaholela esiphethweni samanje.
