Nickel Iron: Feem ntau cov chondrites muaj cov flecks me me ntawm npib tsib xee hlau uas tau nchuav thoob plaws. Vim li no, cov neeg yos hav zoov meteorite feem ntau siv hlau nteshauv thaj chaw uas yuav pom cov meteorites. Ib tug chondrite cov ntsiab lus siab nickel-hlau ua rau nws ua raws li cov hlau nplaum muaj zog.
Koj tuaj yeem qhia tau li cas yog tias koj muaj meteorite?
Meteorites muaj ntau yam khoom uas pab cais lawv ntawm lwm cov pob zeb:
- Qhov ntom: Meteorites feem ntau hnyav rau lawv qhov loj, vim lawv muaj cov hlau hlau thiab cov ntxhia pob zeb ntom ntom.
- Magnetic: Vim feem ntau cov meteorites muaj hlau hlau, cov hlau nplaum feem ntau yuav lo rau lawv.
chondrite zoo li cas?
Txawm hais tias thaum xub thawj zoo tib yam chondrites feem ntau yog grey, thaum lawv tau hloov pauv mus rau lub xeev sib npaug lawv yuav tshwm sim tawm-dawb, thiab qee zaum maj mam tinted txiv kab ntxwv lossis daj. Xwb, yog tias lawv tau xav tsis thoob los ntawm cov txheej txheem cuam tshuam rau saum npoo ntawm lub hnub qub, ces lawv yuav tsaus heev.
Yog chondrites sib nqus?
Cov qib sib nqus zoo tib yam chondrite feem ntau yog Fe - Ni alloys (piv txwv li, Nagata 1979), uas yog lub luag haujlwm rau feem ntau ntawm cov chondrite zoo tib yam thiab feem ntau ntawm cov magnetic susceptibility..
Koj faib cov meteorites li cas?
Meteorites feem ntau muab faib ua peb pawg raws li seb lawv puas muaj cov khoom siv pob zeb ( pob zeb meteorites), cov khoom siv hlau (hlau meteorites), lossis cov khoom sib xyaw (stony– hlau meteorites).
