I-Zircons yimineral ethandwayo phakathi kwezazinzulu kuba belukhuni. Le micrometer-ubungakanani Ikristali inokumelana nemozulu ngaphezulu kweebhiliyoni zeminyaka ukugcina iimfihlo ze-geochemical zokuzalwa kwabo. Bakwabamba i-Iranium ye-I-UNIRUIUM isuka kwindalo njengoko isebenza njengexesha eliqala ngalo mzuzu i-zircons crystallize.ebony yesondo
I-Uranium isotopes iyonke yokukhokela kumazinga anokuqikelelwa. Ngokubala inani leeatom ezikhokelayo eziye zenziwa kunye nee-Uranium Athom, abaphandi banokusebenzisa ukuba lingakanani ixesha elidlulayo ukusukela i-zircons ehle kakhulu kwi-Molden Sen.lesfian
Ababhali bophononongo bafumana i-zircons engeniswe ngesampulu yelitye lenyanga eqokelelwe ngexesha lika-Apollo 17 ngo-1972, kwaye bakha imephu ye-Atom. Ukutsala i-isotopes ekhokelayo kukhokelele kubudala beminyaka eyi-4,46 yebhiliyoni, oyena mdala wokuqulunqwa kwe-lunar.
Eli xesha laligqitywa ngaphambili ngabalandeli bakaGrisi lukhokelwe nguBhadong Zhang no-Audrey Bouvier ngo-2021, kodwa ingxelo yayitsalela i-trupptism. Abagxeki bakhomba kwinto yokuba ii-atom ezikhokelayo zihlala zifuduka ukuba zenze iipokotho zepokotho ephezulu okanye ephantsi kulo lonke elalini. Kuxhomekeka kwiva apho umntu ajonga khona, bekukho ithuba lokuba bafikelele kwezi ndawo ezikhokelayo ezikhokelayo kunye nokungasebenzisi kakuhle ubudala.
Ukuthintela ezi zinto zixhalabisayo, i-bouvier yaya eGreer Greer ukubala kwakhona iathom kwakhona, ngeli xesha nge-ion probe enokuthi iphinde ilukhuni isisombululo esiphezulu sendawo esisetyenzisiweyo kuphoso oludlulileyo. Iprobe ye-firb iya kuvumela iqela ukuba lichonge imimandla ebiyelweyo okanye i-atom ekhokelayo, ukuba ikho. Kodwa bafumana i-HO.GElina Elden ringner ring toll
"Kwezi zircon, yonke into ibinobukroti, ngenxa yoko sasinganyanzelekanga ukuba sikhathazeke malunga naloo nto," utshilo i-cosmochemist kwimyuziyam yasendle kunye neYunivesithi yaseChicago. Iziphumo ziqinisekisile ukuba iminyaka eyayingalinganiyo ye-4.46 yewaka lezigidi ichanekile.
"Kukufunda kakhulu," utsho kakhulu, "utsho kakhulu. I-Barboni ifunde enye i-isotopes kwi-zircons ye-lunar ukuba ifumanise ukuba i-Inter yangaphakathi iguqukele kwi-4,51 yezigidigidi kwiminyaka eyandulelayo i-Crust Shopted kufunda.
I-Barboni ithi uphando olutsha luhambelana neziphumo zakhe. "Amaphepha amaninzi acebisa ukuba inyanga yayisenziwa kakhulu emva koko, iminyaka engama-4 bhiliyoni, umzekelo," wongeza. "Ayinakwenzeka loo datha."
