Ziningi izikhathi lapho inkolelo ivame ukuya kude kakhulu nokwenza. Lesi esinye seziphetho ezimbalwa esingafinyelela kuzo lapho sibhekene nezindaba ezifana nalezi ezisihlanganisa namuhla kule bhulogi. Ukukubeka kumongo kancane, akutshele lokho eLa Tiera kunamaminerali amaningi ukuthi, ngasizathu simbe noma kwesinye futhi naphezu kokuthi ziningi kakhulu, asikaze sizibone ngamehlo.
Njengoba ukwazi ukubona, sikhuluma ngento engabonakala iyinqaba ngokumangazayo, into egcwele kakhulu eMhlabeni kodwa esingakaze siyibone. Noma kunzima 'ukugaya'. Iqiniso ukuthi lokhu yikho kanye okwenzekayo nge i-calcium silicate perovskite, CaSiO3, kuyafana nanamuhla yi amaminerali wesine amaningi kakhulu kule planethi yethu futhi lokho ngokumangazayo futhi, njengoba ngishilo ngaphambili, sasingakaze sibe nethuba lokukucabanga ngamehlo ethu.
Bathola idayimane elinezinto eziningi kakhulu eMhlabeni
Njengoba kungenzeka ucabanga, kukhona iqhinga lakho konke lokhu futhi akulutho ngaphandle kweqiniso elilula lokuthi i-calcium silicate perovskite itholakala ekujuleni koMhlaba, kanye neqiniso lokuthi uma selikhishiwe futhi lenyukela phezulu, ekujuleni kwamakhilomitha angama-650, iba engazinzile. Ukuphela kwendlela yokuqinisekisa ukuthi le nto ikwazile ukukhuphukela phezulu futhi ngaleyo ndlela ikwazi ukukucabanga ukuthi isampula litholakele ngaphakathi kwensimbi encane yedayimane.
Lesi sampula elincane, noma kunalokho idayimane, latholakala, ngokusho kwemibiko eveziwe, ibanga elingaphansi kwekhilomitha ukusuka ebusweni bomhlaba emayini yedayimane yaseCullinan, eseNingizimu Afrika. Njengoba i-geochemist ibeke amazwana UGraham pearson mayelana:
Akekho okwazile ukugcina lokhu okumbiwa phansi kuzinzile ebusweni bomhlaba. Ukuphela kwendlela ongayigcina ngayo ebusweni kulapho ibhajwe esitsheni esingaguquguquki njengedayimane.
Ingubo engezansi yoMhlaba yakhiwe nge-90% calcium silicate perovskite
Ukuze uthole umbono, udinga nje ukusesha okuncane kwe-inthanethi ukuthola ukuthi kungani i-calcium silicate perovskite ingenye yezinto eziningi kakhulu emhlabeni, ngokusho kososayensi. le ndaba empeleni yakha ngaphezu kuka-90% wengubo ephansi yoMhlaba. Ngokumangazayo, naphezu kweqiniso lokuthi, njengoba ubona, lokho kwabhabhadiswa ngaleso sikhathi nokwakheka kwaso kuyaziwa, iqiniso ukuthi akekho ososayensi abekade bezibona ngamehlo abo kuze kube manje, ngaleso sikhathi, ekugcineni , kunobufakazi obucacile bokuba khona kwaleli mineral.
Okwamanje, njengoba ucabanga nje, kunososayensi nabaphenyi abaningi asebeke baxhumana nabagcini balolu daba ukubenza babanikeze ilayisense ebavumela ukuthi bakwazi zitadishe ngokuningiliziwe futhi ngaleyo ndlela ikwazi ukwazi ukuthi kungani, uma isikhuphukele phezulu, iba engazinzile kangangoba ize inyamalale, into engenzeki ngezinye izinto eziningi ezifana, ngokwesibonelo, idayimane.
Idayimane elitholakele, nalo, lingesinye sezimanga kakhulu esike sembiwa kuze kube manje
Enye imininingwane ethakazelisa kakhulu ngaleli minerali itholakala ngqo esitsheni esenza ukuthi ukutholakala kwayo kwenzeke. Ngikhuluma ngedayimane uqobo lwalo, elingamamilimitha ayi-0 kuphela ububanzi futhi, ngokusho kososayensi, eliyivelakancane ngokweqile kusukela, ngokungafani nawo wonke amadayimane azalwa ebangeni eliphakathi kwamakhilomitha ayi-031 nama-150 ukusuka ebusweni bomhlaba, lokhu kudalwe ngamakhilomitha angama-700 ukujula.
Ukukunika umbono, kulokho kujula ingcindezi cishe izikhathi ezingama-240.000 ingcindezi ekhona olwandle. Le ngcindezi enkulu ibhekene ngqo nale dayimane, ekudalweni kwayo, ibamba i-calcium silicate perovskite ngaphakathi. Ngokusho UGraham pearson:
Amadayimane ayindlela eyingqayizivele yokubona ukuthi yini esemhlabeni. Futhi ukwakheka okuthile kokufakwa kwe-perovskite kulelo dayimane elithile kukhombisa ngokusobala ukuvuselelwa koqweqwe lwasolwandle engubeni engezansi yoMhlaba. Inikeza ubufakazi obuyisisekelo bokuthi kwenzakalani ngesiphetho samacwecwe asolwandle njengoba ehlela phakathi eMhlabeni.
