Ib txheej txheem uas dolostone tuaj yeem tsim tau yog los ntawm txhais tau tias nag lossis daus ntawm calcium magnesium carbonate los ntawm dej hiav txwv. Lwm cov txheej txheem yog rau dolomite kom maj mam hloov cov calcite ntawm limestone tom qab cov limestone tau tso. … Dolostone tau tsim nyob rau hauv dej sov, ntshiab, ntiav dej hiav txwv thaum lub sij hawm Paleozoic Era.
Puas yog dolostone chemically tsim?
Dolomite yog ib hom pob zeb tsim pob zeb. Nws yog calcium magnesium carbonate nrog tshuaj muaj pes tsawg leeg ntawm CaMg (CO 3) 2. Nws yog thawj feem ntawm cov pob zeb sedimentary hu ua dolostone thiab cov pob zeb metamorphic hu ua dolomic marble. Limestone uas muaj qee cov dolomite hu ua dolomite limestone.
Puas yog dolostone yog dolomite?
Dolostone yog pob zeb zoo-grained sedimentary feem ntau ntawm dolomite, calcium thiab magnesium carbonate mineral.
Micrite yog dab tsi?
Micrite, pob zeb sedimentary tsim los ntawm cov khoom calcareousqhov ntev ntawm 0.06 txog 2 hli (0.002 txog 0.08 nti) uas tau muab tso rau hauv mechanically es tsis yog los ntawm kev daws.
Ooids hnub nyoog pes tsawg?
3500–4500 xyoo uas tau pom zoo nrog calibrated AMS 14C hnub nyoog ntawm 3370F50 xyoo BP ntawm tib yam khoom. Yog li, cov ooids tau tsim, thauj, emplaced, muaj zog cemented, thiab loj eroded los ntawm ntug hiav txwv dej nyob rau hauv tsuas yog 3400 xyoo.

Yuav ua li cas sau ntawv thiab yuav ua li cas?
Tab sis tiag tiag, sau ntawv tsuas yog txhais tau tias tso tseg me ntsis nyob ntsiag to, tsis muaj sijhawm los zaum thiab xav txog koj lub neej. Nws tuaj yeem yog los ntawm kev sau cov ntaub ntawv ntawm qhov koj tau ua hnub ntawd; los ntawm venting txog ib yam uas koj tsis tuaj yeem tawm ntawm koj lub siab;

Puas pom qhov tseem ceeb yog vim li cas lossis vim li cas ho tsis?
Kev sib txuas lus pom kev pab cov neeg tuaj saib nkag siab cov ntaub ntawv. Nws ua rau kom nkag siab txog cov ntsiab lus. Hom duab ob sab uas pab kev sib txuas lus muaj xws li kos duab, kos duab kos duab, animation, kos npe, typography, graphic designs, thiab lwm yam.
Puas yog dolostone yog pob zeb lossis tsis yog?
Dolostone zoo ib yam li limestone, tab sis feem ntau yog cov ntxhia dolomite (CaMg (CO3)2). Ob leeg yog pob zeb sedimentary uas tshwm sim li nyias mus rau cov txaj loj ntawm nplua-rau pob zeb coarse-grained. Lawv cov xim feem ntau yog qee qhov ntxoov ntxoo ntawm grey, tab sis tej zaum yuav yog dawb, tan, daj, liab, ntshav, reddish xim av, xim av, los yog dub.
Vim li cas dolostone tsim?
Dolostone cov ntaub ntawv thaum magnesium nyob rau hauv pore dej yog hloov rau qee cov calcium nyob rau hauv thawj limestone, los yog los ntawm dej nag ncaj qha. Feem ntau cov limestones ntawm kev lag luam tseem ceeb tau sau nyob rau hauv qhov chaw ntiav dej hiav txwv thiab muaj dav rau kev siv.
