Pob zeb diamond yog ua ntawm carbon thiaj li tsim raws li carbon atoms nyob rau hauv ib tug kub kub thiab siab ; lawv khi ua ke kom pib loj hlob muaju.
Yog li ntawd, nws yuav siv sij hawm ntau npaum li cas los ua lub pob zeb diamond?
Kev kub siab ntawm kwv yees li 725,000 kip ib square inch yog siv rau cov pa roj carbon. Pob zeb diamond nce mus rau lub ntiaj teb saum npoo kom txias.
Ib sab saum toj no, yuav ua li cas lub pob zeb diamond dhau los ua pob zeb diamond? Pob zeb diamond tau tsim ntau dua 3 billion xyoo dhau los sib sib zog nqus hauv lub ntiaj teb lub pob zeb nyob rau hauv cov xwm txheej ntawm cov cua sov thiab siab uas ua rau carbon atoms crystallize tsim. pob zeb diamond . Qhov kev nthuav dav no ua rau lub magma tawg, yuam nws mus rau lub ntiaj teb saum npoo thiab coj nrog nws pob zeb diamond bearing pob zeb.
Ib tug kuj nug, yuav ua li cas yog pob zeb diamond tiag tiag?
Pob zeb diamond yog tsim nyob rau hauv lub ntiaj teb lub mantle, qhov chaw ntawm 1 thiab 3 billion xyoo dhau los. Tsim los ntawm tshav kub thiab siab, pob zeb diamond Tom qab ntawd xa mus rau lub ntiaj teb saum npoo av los ntawm qhov tob ntawm volcanic eruptions los yog txav ntawm subduction zones uas coj cov pob zeb diamond mus txog ntawm ntug dej hiav txwv.
Yuav siv sijhawm ntev npaum li cas rau cov thee los ua pob zeb diamond?
3 billion xyoo

Yuav ua li cas lub pob zeb sedimentary ua ib lub pob zeb metamorphic?
Sedimentary pob zeb ua metamorphic nyob rau hauv lub pob zeb voj voog thaum lawv raug tshav kub thiab siab los ntawm faus. Cov kub kub yog tsim thaum lub ntiaj teb daim hlau tectonic txav ib ncig, ua kom sov. Thiab thaum lawv sib tsoo, lawv tsim roob thiab metamorphose
Lub npe rau lub pob zeb nruab nrab ntawm cov pob zeb uas txias heev yog dab tsi?
Extrusive igneous pob zeb
Vim li cas lub melting point ntawm pob zeb diamond siab dua graphite?
Nyob rau hauv pob zeb diamond valence electrons yog tag nrho covalently bonded. Tab sis nyob rau hauv graphite tsuas yog peb yog covalently bonded thaum ib tug electron yog dawb do txav.Yog li ntawd nws zoo li hais tias melting point ntawm pob zeb diamond yuav tsum siab tshaj li ntawm graphite vim hais tias nyob rau hauv pob zeb diamond peb yuav tsum tawg plaub covalent bonds thaum nyob rau hauv graphite tsuas yog peb daim ntawv cog lus
Dab tsi yog qib siab tshaj plaws rau NFPA pob zeb diamond phom sij?
Number System: NFPA Rating thiab OSHA's Classification System 0-4 0-yam txaus ntshai 4-mob txaus ntshai tshaj plaws 1-4 1-mob hnyav tshaj plaws 4-tsawg kawg nkaus txaus ntshai • Cov naj npawb Hazard tsis tas yuav tsum muaj nyob rau ntawm cov ntawv tab sis yuav tsum tau ntawm SDSs hauv ntu 2
Cov pob zeb hauv av twg tuaj yeem tsim cov pob zeb zoo li lub raum?
Hematite (los yog haematite) Kuj tseem muaj ntau hom hematite, qee yam yog: raum ore, ib qho loj, botryoidal (lumpy) lossis reniform (lub raum zoo li tus) daim ntawv; specularite, micaceous (flaky) daim ntawv; oolitic, ib daim ntawv sedimentary tsim los ntawm cov nplej me me; liab ochre, ib daim ntawv liab earthy
