Cov kws tshawb fawb tau qhia tias vim li cas cov pob zeb liab liab tsis tshua muaj, AFP tau tshaj tawm, hais txog kev tshawb fawb tshawb fawb. Cov pob zeb no pom yuav luag tshwj xeeb hauv Australia. Lawv tus nqi yog siab heev.
Ntau tshaj 90 feem pua ntawm lub ntiaj teb cov pob zeb liab liab yog mined ntawm Argyle mine nyob rau sab qaum teb hnub poob ntawm lub teb chaws, uas tam sim no raug kaw.
Feem ntau ntawm cov pob zeb diamond mining mines nyob rau lwm lub teb chaws - piv txwv li hauv South Africa thiab Russia.
Ib pab neeg tshawb fawb Australian tau ua ib txoj kev tshawb fawb luam tawm nyob rau hauv "Nature Communications", raws li cov pob zeb diamond liab tau tsim thaum thawj lub ntiaj teb supercontinent tawg 1.3 billion xyoo dhau los.
Ob lub ntsiab lus xav tau los tsim lub pob zeb diamond, University of Perth geologist Hugo Olieruk hais rau AFP. Thawj cov khoom yog carbon. Ntawm qhov tsawg dua 150 km qhov tob, carbon yog pom nyob rau hauv daim ntawv ntawm graphite. Qhov thib ob tivthaiv yog siab siab. Nws muaj peev xwm txiav txim siab xim ntawm pob zeb diamond. Tsawg siab ua rau cov xim liab, thiab me ntsis siab dua ua rau xim av, Olieruk piav qhia.
Raws li Olieruk, cov txheej txheem geological ntawm kev sib cais ntawm tib lub teb chaws loj hauv ntiaj teb tau thawb cov pob zeb liab liab mus rau saum npoo ntawm Australia niaj hnub no xws li champagne corks.
