Chondrules yog pob zeb tsis pom kev pom nyob rau hauv chondritic meteorites, uas yog cov meteorites ntau tshaj plaws pom hauv ntiaj teb. Cov pob zeb no muab kev tshawb fawb nrog lub hnub nyoog ntawm Hnub Ci System thiab muaj cov ntaub ntawv ntawm thawj cov khib nyiab los tsim thiab hloov zuj zus nyob rau lub sijhawm ntxov tshaj plaws ntawm Solar System tsim.
chondrites nyob qhov twg?
Chondrites yog cov chav kawm meteorite ntau tshaj plaws, suav nrog ntau dua 85 feem pua ntawm cov meteorite ntog. Zoo li feem ntau meteorites, chondrites originated nyob rau hauv lub asteroid sivqhov twg kev sib tsoo thiab gravitational perturbations muab lawv mus rau hauv lub ntiaj teb-hloov orbits. (Cov chondrites ib txwm, tshwj xeeb, yog los ntawm S-class asteroids.)
Puas tag nrho cov chondrites muaj chondrules?
Feem ntau chondrites muaj ob hom I thiab Hom II chondrules sib xyaw ua ke, suav nrog cov porphyritic thiab nonporphyritic textures, txawm hais tias muaj kev zam rau qhov no.
chondrules zoo li cas?
yam ntxwv. Tseem ceeb ntawm cov khoom uas muaj nyob rau hauv chondrites yog cov enigmatic chondrules, millimetre-loj spherical khoom uas yog los ntawm kev ywj pheej ntab, molten los yog ib nrab molten droplets hauv qhov chaw; chondrules feem ntau yog nplua nuj nyob rau hauv silicate minerals olivine thiab pyroxene.
chondrules zoo li cas ntawm lub meteorite?
Primitive chondrites
Cov hom meteorites no feem ntau muaj dub grey los yog dub fusion crust thiab lub teeb grey sab hauv… Feem ntau cov ntxhia hauv lub ntiaj teb crust, chondrites primitive yuav tsis xav tias hnyav hnyav rau lawv qhov loj me.
