Chowopsya kuchokera ku danga - Skhote-Alin meteorite

Pa February 12, 1947, m'dera la Primorye Territory mazana ambirimbiri a chitsulo anagwa pansi. Chifukwa cha tsokali chinali Sikhote-Alin meteorite, yomwe inagwa mumlengalenga ndi kugawidwa m'magulu ambiri. Iye anakhala chimodzi mwa meteorites yaikulu kwambiri yomwe inayamba kugwera ku Dziko. Kuwonjezera apo, meteorite iyi ili ndi zinthu zambiri zomwe zimapangitsa kuti zikhale zosiyana. Mwachitsanzo, ili ndi mankhwala ofanana, koma si crystal imodzi, koma ili ndi makina ambiri, osakanikirana kwambiri, omwe amachititsa kuti pakhale kusiyana.

Zoona za sayansi

Methiorite inagwa makilomita 46 m'litali kumpoto ndi 134 degrees 39 mphindi zakummawa. Zowonongeka zinagwa m'dera la 12x4 km. Pali makina makumi awiri mphambu anayi omwe ali pamwamba pake, omwe mamita ake ndi mamita asanu ndi anai, komanso mapiri ang'onoang'ono. Unyinji wa mankhwala omwe unasonkhanitsidwa ndi matani oposa makumi asanu ndi awiri mphambu zisanu ndi ziwiri. Malinga ndi chiyambi chakumlengalenga kwa meteorite, kunali kotheka kuzindikira kuti iyo inachoka kuchokera pakati pa bwalo la meteorite.

Mphepete yam'madzi yotchedwa Sikhote-Alin inachititsa kuti zinthu zina zisinthe. Mitsinje iwiri pafupi ndi malo a kugwa kwake tsopano ali ndi mayina a Meteorite Yaikulu ndi Yaikulu, yomwe ili pafupi kwambiri ndi malo omwe inakhazikitsidwapo imatchulidwanso mwa ulemu wake. Dera lomwelo linakhala chikumbutso cha chirengedwe.

Zosangalatsa

Mu 1976, panali chochitika chosangalatsa chogwirizanitsidwa ndi meteorite iyi. Mphuno yake inapezeka mu bedi la malasha, koma osati m'dera la Sikhote-Alin, koma pafupi ndi Donetsk, pambuyo pake idasamutsira ku Meteorite Commission, komwe inalembedwa ngati mgodi wa malasha wosiyana ndi dzina lake Marinka. Patatha zaka khumi zokha, pofufuza zomwe zili mkati mwake, cholakwikacho chinapezedwa ndikuchotsedweratu, ndipo izi zisanachitike, chidutswa chimenecho chinkaonedwa kuti ndi chakale kwambiri padziko lapansi.

Panali asayansi ambiri amene anafufuza mokhulupirika Meteorite-Alin meteorite. Ena mwa iwo, E.L. Krinov, E.I. Malinkin, yemwe adachita nawo maulendo khumi ndi asanu, V.I. Tsvetkov, amenenso adatengapo gawo ndikupita nawo maulendo ena. Kuwonjezera pa iwo, Academician Fesenkov, Dokotala wa Sayansi, Dewari, akatswiri a sayansi ya zakuthambo Gorshkov ndi Guskova, Aologne ndi Kestlane, madokotala a Sciences Semenenko, Lavrukhin, masamu a masamu ndi ena ambiri adagwira nawo ntchitoyi. Ambiri mwa iwo anali asayansi omwe anafufuza Tunguska. Choncho, m'mabuku awo, nthawi zambiri zimakhala zofananitsa ndi meteorites zazikulu kwambiri.

Kulumikizana ndi Tunguska meteorite

Mphepete yam'madzi yotchedwa Sikhote-Alin ingatchulidwe, mwa njira ina, yotsutsana ndi Tunguska. Mwachitsanzo:

• Woyamba ankawuluka pafupi masekondi asanu, ndipo chachiwiri - mphindi pang'ono;
• Choyamba chinaphulika mlengalenga, chachiwiri chinagunda pansi;
• Palibe zinthu za thupi la cosmic pa Tunguska;
• Kuwonekera kwa moto kumapiri kilomita 140 ndi 700 kilomita, motero;
• Zambiri za m'mlengalenga za m'mlengalenga ndizomwe zimachitikira mchere wa Tunguska ndipo ndizochepa kuchokera ku Sikhote-Alinsky.

Meteorite yomwe inagwa mu Sikhote-Alin ndiyo yaikulu padziko lonse lapansi, koma kuyendetsa kwake kunatsagana ndi ziwerengero zing'onozing'ono zophatikizapo. Mu Tungus, komabe, palibe zochitika za thupi lakumwamba , koma panali zochitika zowononga zowonongeka mu kugwa.
