Uninzi lwezihlandlo apho ithiyori ithanda ukuba phambili kakhulu kokuziqhelanisa. Ngokuchanekileyo esi sesinye sezigqibo ezimbalwa esinokufikelela kuzo kwiindaba ezinjengezo zisidibanisayo namhlanje kule bhlog. Ukukubeka kumxholo kancinci, ndikuxelele eLa Tiera kukho izimbiwa ezininzi ukuba, ngenxa yezizathu ezithile okanye enye kwaye nangona baninzi kakhulu, zange sababona ngamehlo ethu.
Njengoko ubona, sithetha ngento enokubonakala ingaqhelekanga, into eninzi kakhulu eMhlabeni kodwa esingazange siyibone. Nangona kunzima 'ukwetyisa'. Inyani yile yokuba le yinto kanye eyenzekayo I-calcium silicate perovskite, CaSiO3, iyafana nanamhlanje yesine izimbiwa ezininzi kulo mhlaba wethu kwaye loo nto inomdla kwaye, njengoko benditshilo ngaphambili, asikaze sibe nethuba lokucingisisa ngamehlo ethu.
Bafumana idayimane enezona zinto zininzi kakhulu emhlabeni ngaphakathi
Njengoko unokucinga, kukho iqhinga kuyo yonke le nto kwaye ayisiyonto iyenye ngaphandle kwento elula yokuba i-calcium silicate perovskite ifumaneka nzulu eMhlabeni, kunye nenyaniso yokuba yakuba ikhutshiwe kwaye inyukele phezulu, kubunzulu beekhilomitha ezingama-650, iya ingazinzi. Ekuphela kwendlela yokuqinisekisa ukuba lo mbhalo ukwazile ukuphakama uye ngaphezulu kwaye ke ngoko ukwazi ukuwucamngca ngokufumana isampulu ngaphakathi kwento encinci yedayimani.
Le sampuli incinci, okanye mandithi idayimane, yafunyanwa, ngokweengxelo eziveziweyo, ngaphantsi kwekhilomitha ukusuka kubuso bomhlaba kumgodi wedayimani waseCullinan, obekwe eMzantsi Afrika. Njengoko i-geochemist iye yaphawula UGraham pearson malunga:
Akukho mntu ukwazileyo ukugcina le minerali izinzile phezu komhlaba. Ekuphela kwendlela yokuyigcina phezu komhlaba kuxa ivaleleke kwisitya esingaguqukiyo esifana nedayimane.
Ingubo engezantsi yoMhlaba yenziwe nge-90% ye-calcium silicate perovskite
Ukufumana umbono, kuya kufuneka wenze uphando oluncinci lwe-intanethi ukufumanisa ukuba kutheni i-calcium silicate perovskite yenye yezona zinto zininzi emhlabeni, ngokutsho kwezazinzulu. Lo mbandela ngokoqobo wenza ngaphezu kwe-90% yengubo engezantsi yoMhlaba. Ngokumangalisayo, kwaye ngaphandle kwento yokuba, njengoko ubona, izinto zazibhaptizwa ngelo xesha kwaye ukwakhiwa kwayo kuyaziwa, inyani kukuba akukho nzulu-lwazi ebekhe yakwazi ukuyibona ngamehlo kude kube ngoku, ngelo xesha, ekugqibeleni , Kukho ubungqina obunokubambeka bobukho beli zimbiwa.
Okwangoku, njengoko uqinisekile ukuba unokucinga, zininzi izazinzulu kunye nabaphandi esele benxibelelana nabagcini bezinto ukubenza babanike iphepha-mvume elibavumela ukuba bakwazi bafunde ngakumbi kwaye ke ukwazi ukwazi ukuba kutheni, yakuba inyukele phezulu, iye ingazinzisi kangangokuba inyamalale, into engenzekiyo nezinye izinto ezinje, umzekelo, idayimani.
Idayimani efunyenwe, yona, yenye yezona zimangalisayo ziye zambiwa ukuza kuthi ga ngoku
Enye inkcukacha enomdla malunga nale minerali ifumaneka ngokuchanekileyo kwisitya esenza ukuba ukufunyanwa kwayo kwenzeke. Ndithetha ngedayimani uqobo lwayo, enobubanzi obuyi-0 yeemilimitha ububanzi kwaye, ngokutsho kwezazinzulu, inqabile kakhulu ukusukela, ngokungafaniyo nazo zonke iidayimani ezizalwe kumgama ophakathi kwe-031 ne-150 yeekhilomitha ukusuka kumphezulu womhlaba, oku kudalwe kubunzulu beekhilomitha ezingama-700.
Ukukunika umbono, kubunzulu boxinzelelo malunga nama-240.000 amaxesha oxinzelelo olukhoyo elwandle. Olu xinzelelo lukhulu luxanduva oluchanekileyo kule dayimane, ekudalweni kwayo, ukuloba i-calcium silicate perovskite ngaphakathi kwayo. Ngokutsho UGraham pearson:
Iidayimani ziindlela ezizodwa zokubona okusemhlabeni. Kwaye ukwakheka okuthe ngqo kokufakwa kwe-perovskite kuloo dayimani ibonakalisa ngokucacileyo ukuphinda kusetyenziswe kwakhona ingqweqwe lwaselwandle kwingubo engezantsi yoMhlaba. Inika ubungqina obusisiseko bokwenzekayo kwisiphelo samacwecwe olwandle njengoko besihla singena nzulu eMhlabeni.
