Ngezinye izikhathi imvelo isiphonsa izimfihlo ezinjalo, ukuthi azixazululwe hhayi ngeminyaka, kodwa ngamakhulu eminyaka. Enye yalezi zimfihlakalo kwakuyitshe elingavamile endaweni yeNamibia .
Ukutholwa komlando
Kwakuyihlobo elomile lika-1920. Lokhu kwenzeka epulazini laseHoba West Farm eduze kwedolobha laseHrutfontein . Etshala enye yamasimu akhe futhi ecabanga ngezizathu zokuvuna okuncane, umlimi uJacobus Hermanus Brits wangcwatshwa umlimi ngesimo esithile somgoqo. Ilukuluku lwalukhona, futhi wagijimela ezweni lakhe. UJamesbus wazama isikhathi eside ukuthola imiphetho yalokho athola, futhi ukumangala kwakhe kwakungenasiphelo lapho ebona lokho ayekutholile ngempela. Kuleyo mizuzu, umlimi wayengakwazi ngisho nokucabanga ukuthi wayezoqhubeka eqhubeka negama lakhe emlandweni. Ukutholwa akuthola akuyona into ngaphandle kwe-meteorite enkulu emhlabeni.
Igama elithi Goba (Khoba) lamanzi elitholwa ngokuhlonipha umhlaba wokulima, owatholwa. Ngomumo, lifana kakhulu ne-parallelepiped, kanti ubukhulu buyamangalisa: 2.7 ngamamitha angu-2.7 ubude futhi ubude buka-0.9 wamamitha. Esithombeni ngezansi ungabona i-meteorite i-Goba kuyo yonke ubukhulu bayo.
Iyini imeteorite?
I-Goba (i-English Hoba) - i-meteorites enkulu kunazo zonke ezitholakale emhlabeni. Usengaphansi kokuwa kwakhe, eningizimu-ntshonalanga ye-Afrika, eNamibia. Ngaphezu kwalokho, namuhla yiyona insimbi enkulu kakhulu yemvelo yemvelaphi yemvelo.
Amaqiniso anentshisekelo mayelana ne-Goba meteor eNamibia:
- Ososayensi banqume ukuthi imvula yaseGob ingu-410 million ubudala ubudala, futhi ulele esitelekeni sokuwa kwakhe eminyakeni engu-80 eyedlule.
- Ngesikhathi esithola ukuthi unesisindo samathani angama-66, namuhla le nombolo iye yehliswa kakhulu - amathani angu-60. Lokhu kubeka icala lokushisa nezidakamizwa. Ukuze uthole ulwazi, iningi lamameteorite eliwela eMhlabeni lalinesisindo kusuka kwamagremu amaningana kuya kwamashumi ama-kilogram.
- Ukubunjwa kwe-Goba meteorite ingu-84% yensimbi, i-nickel engu-16% enenani elincane le-cobalt, futhi ngaphandle kwalo limbozwe nge-hydroxyde ensimbi. Ngokusho kwesakhiwo sekristalline, i-Goba meteorite i-ataxite ecebile ku-nickel.
- Umlando Wezemvelo WaseNew York ngo-1954 uhlele ukuthenga i-meteorite ukuze uvezwe, kodwa kwakukhona ubunzima bokuhamba, futhi uGoba wahlala elele endaweni yawo.
- Emkhatsini wemvula enkulu kunazo zonke zomhlaba iyimbumbano encane lapho izinkulumo kanye nezenzo zivame ukuhlelwa khona. Futhi ngonyaka odumayo, abantu bendawo bahlela umdanso wesiko eduze kwetshe. Ngeshwa, abaseYurophu abavunyelwe lapho.
Isikhumbuzo Sezwe
Lapho izindaba ze-meteorite ngesivinini sokukhanya zihamba emhlabeni wonke, izinkulungwane zabantu zazithelela eNamibia. Wonke umuntu wazama ukuzibamba inkumbulo. Kusukela ngo-March 1955, uhulumeni weseningizimu-ntshonalanga yeAfrika umemezele ukuthi isikhumbuzo sezwe sikaGob siyisikhumbuzo sesizwe, ngaleyo ndlela sivikela ilitshe eliyingqayizivele ekubhujisweni. Rossing Uranium Ltd. ngo-1985, kwaxhasa uhulumeni weseningizimu-ntshonalanga ye-Afrika ukuqinisa ukuvikelwa kwe-meteorite. Futhi eminyakeni emibili kamuva, umnikazi wepulazi iHoba West wanikeza umbuso i-meteorite iGoba nomhlaba owawuzungezile. Ukuze kube nokuphepha okungcono, kunqunywe ukuthi angayithutheli i-meteorite noma yikuphi, kodwa ukuyiyeka endaweni yeHoba West Farm. Ngokushesha, isikhungo sezokuvakasha savuleka kule ndawo. Njalo ngonyaka ukugeleza kwezivakashi ezifuna ukubona nokuthinta iMeteorite i-Gob kukhula nje, futhi izenzo zokulimaza ziye zayeka.
Izimfihlakalo ze-meteorite
Ososayensi abaningi basabisa ubuchopho babo, bevula izimfihlo zeMogra Meteorite eNamibia. Futhi baneziningana:
- Ifomu le-meteorite i-parallelepiped engavamile, "izivakashi" ezinjalo zivame ukuwela eplanethi yethu, ukugcina ifomu elihle lejometri;
- I-Goba ebushelelezi futhi ifane kahle, iyinhlangano yensimbi enamandla;
- eduze kwalo akusikho i-crater noma yimuphi omunye umkhondo kusukela ekuwa. Lokhu kungenzeka kanjani? Phela, inhlama enjalo kwakufanele ihlakazeke ibe ngamakhulu amaqhezu phakathi nendiza. Mhlawumbe umkhathi womhlaba wehla lapho i-meteorite iwa, futhi kwakungekho ukukhululeka kwamandla amakhulu;
- iningi lishaya phambili enye inkolelo yokuwa kweGob meteorite: ukushaya phansi, uvele nje uvele, uhlasele endaweni yokuwa ibanga elide, ngakho-ke awekho umkhondo.
Kungakhathaliseki ukuthi kwakunjani, kodwa imibuzo eminingi ayisaphenduliwe.
Ungafika kanjani?
Ungaqasha imoto esikhumulweni sezindiza sase-Grootfontein, esitholakala kuphela ku-5 km ukusuka emzini waseHrutfontein . Ukuthutha komphakathi ukuya epulazini laseGoba akuhambanga. Futhi kukhona okuhlukile kokuqasha imoto nomshayeli. Izivakashi eziningi ziyayikhetha, ngoba kufanele uhambe ngaphesheya komgwaqo, ulele endaweni yasehlane. Kusuka eHrutfontein kuya emkhathini weGoba ibanga elingamakhilomitha angama-23, uhambo luzothatha imizuzu engu-20.
