Ferro Silicide, FeSi2

Yuri lavbin, tus thawj coj ntawm lub tungusian cosmological phenomena foundation, tau tshawb pom cov kua roj silicon hu ua "ferrosilicide" uas tsis tuaj yeem tsim nyob rau hauv qhov xwm.

1: Yuri lavbin, tus thawj coj ntawm lub tungusian cosmological phenomena foundation, tau pom lub pob zeb silicon hu ua "ferrosilicide" uas tsis tuaj yeem tsim nyob rau hauv qhov xwm txheej: lub ntuj silicified hlau, piv txwv li disilicite, tau pom thawj zaug hauv Devonian sandstone raws ntug dej hiav txwv ntawm Soviet Union. Lub sijhawm ntawd, nws tau kwv yees tias kev tsim kho pob zeb ntawm lub hnub qub yog meteorite [4], thiab tus neeg tshawb nrhiav kuj yog tus qub tub txawg hauv xeev Soviet. Tsis tas li ntawd, muaj ntau daim ntawv tshaj tawm hauv tebchaws, thiab ntau ntawm lawv tsis yog hnub qub hlau tab sis magmatic keeb kwm ntawm txhua [2], uas tseem tau qhia meej hauv cov ntawv nyeem.
2: Neon, xenon, argon Nws yog tsis yooj yim sua kom muaj kev sib xyaw ntawm cov khoom siv los tsim hauv ntiaj teb ib puag ncig Qhov tseeb: Neon [5], xenon [5], argon [6] feem ntau muaj nyob hauv cov qauv ntsuas geological, thiab tuaj yeem siv rau nws kev kawm tob ntawm cov neeg hlau thiab cov sijhawm thiab cov sijhawm coj ua, tuaj yeem pom.
3: Txawm hais tias cov cuab yeej siv hluav taws xob muaj zog tshaj plaws tsuas yog tso tawm me ntsis ntawm cov hlau silicide Qhov tseeb: Ferrosilicon muaj qhov nyuaj txog li 6.5 [7], nyob ntawm hom, thiab nws tseem nyuaj tshaj li ntawm cov quartz (piv txwv li, siv lead ua, uas muaj qhov nyuaj ntawm 7).
Los suav, cov lus xaiv dhau los uas Tungus nrhiav pom tus neeg txawv teb chaws "hlau ua haujlwm" tau tso los ntawm txawv teb chaws muaj kev tshawb fawb txog kev puas tsuaj, tsis muaj kev ntseeg siab, thiab yuav tsum tsis txhob tshaj tawm xov xwm.
