Nenhlekelele kusuka isikhala - Sikhote-Alin meteorite

Nambili ngo-February 1947, esifundeni Primorsky wawela phansi, amakhulu ezinkulungwane izingcezu ezincane zensimbi. Isizathu salokhu inhlekelele wakhonza Sikhote-Alin emkhathini hit emkhathini woMhlaba, futhi ahlukaniselwe yizicucu. Waba emkhathini omkhulu kunayo yonke eyake uwela phansi. Ngaphezu kwalokho, lokhu meteorite enezinto eziningi izici ezenza kube esiyingqayizivele. Ngokwesibonelo, it has a iyunifomu amakhemikhali ukwakheka, kodwa hhayi crystal olulodwa, futhi siqukethe zinhlayiya eziningi kabi oxhumene, okuyinto cishe ombangela yokuhlukanisa yayo.

namaqiniso esayensi

Metiorit bawela degrees 46 imizuzu engu-10 enyakatho nenkabazwe kanye degrees 134 amaminithi 39 longitude empumalanga. Fragments kwehla phezu ensimini endaweni 12h4 amakhilomitha. It has amabili nane emgodini ngenhloso ububanzi - amamitha angaphezu kuka eziyisishiyagalolunye, kanye asemigodini eziningi ezincane. IMisa efana okungukuthi ikwazi ukuqoqa, kuyinto amathani angaphezu kuka amabili nesikhombisa. Ngokusho trajectory Oku-asemkhathini of meteorite bakwazi ukunquma ukuthi wavela ngumgogodla ibhande Meteor.

Sikhote-Alin meteorite wabangela ukuqanjwa kabusha kwezinye izici zokuma kwezwe. Ukusakaza ababili etholakala eduze indawo wokuwa, manje esibizwa ngokuthi Small futhi Meteor elikhulu, edolobhaneni eliseduze lase futhi ogama lakhe behlonipha yakhe. Isifunda baba semvelo.

izici ezithakazelisayo

Ngo-1976, kwaba khona isehlakalo ezihlekisayo elihlobene ne meteorite. shard wayo itholwe kumiswa amalahle, kodwa hhayi endaweni Sikhote-Alin, futhi eduze laseDonetsk ke wadluliselwa Commission on emkhathini, lapho yabhaliswa njengoba ehlukile futhi wamnika igama Marinka. iminyaka kuphela ngemva eziyishumi ukuhlaziya iphutha wokuqukethwe ubonakele futhi iqedwe, futhi phambi lokho kwakubhekwa njengobufakazi wesandla omdala we meteorite Emhlabeni.

Kwakukhona ososayensi abambalwa ababezama devotedly kakhulu watadisha Sikhote-Alin meteorite. Phakathi kwabo, EL Krinov, EI Malinkin, owaba nengxenye zonke mikhankaso nanhlanu, VI Tsvetkov, naye waba nengxenye nabo, ngisho nalapho abanye owayehola iqembu elathatha uhambo. Ngaphandle kwabo, isifundo abathintekayo Academician Fesenkov, PhD Divari, Geophysics Gorshkov futhi Guskov, eTallinn izazi zokuma komhlaba Aaloe futhi Kestlane, Doctor of Science Semenenko, Lavrukhina sezibalo Boyarkina nabanye abaningi - ikakhulukazi, bonke ososayensi ababefunda Tunguska. Ngakho-ke, ezisezincwadini zabo ngokuvamile atholakala ngokufaniswa emkhathini ezimbili ezinkulu.

Ukuxhumana ne Tunguska meteorite

Sikhote-Alin meteorite kungenziwa ngokuthi endaweni antipode umqondo tunguska. Ngokwesibonelo:

• kuqala flying mayelana imizuzwana emihlanu, kanti eyesibili - imizuzu embalwa;
• kuqala yamila emoyeni, kanti eyesibili - hit umhlabathi;
• Tunguska umzimba cosmic kungakhathaliseki;
• le sobala trajectory izimoto - ngokulandelana 140 amakhilomitha futhi amakhilomitha 700;
• kwenkululeko anomalies asemkhathini - Global endabeni le Tunguska kwemvula yezinkanyezi ezinomsila, futhi kuphela ngalezi Sikhote-Alin.

I kwemvula yezinkanyezi ezinomsila, okuyinto yawela Sikhote-Alin Ukhahlamba, iyona enkulu kunazo zonke emhlabeni, kodwa lokubikezela yayo kwakulandelwa inombolo encane imihlola ahlobene. I Tunguska futhi komkhondo ka nendikimba ethile esemkhathini angekho, kodwa kwakukhona izenzakalo adukisako ekwindla.
