Yog li ntawd, Diatomite yog dab tsi?

Diatomite yog hmoov ntxhia muaj li ntawm cov fossilized seem ntawm microscopic ib leeg-celled dej nroj tsuag hu ua diatoms. Diatoms tuaj yeem nqus dej-soluble silica tshwj xeeb los ua ib qho ntxeem tau, tab sis lub cev pob txha nruj ntawm amorphous silica.

Ib yam li ntawd, hom sediment yog diatomaceous ntiaj teb? Diatomaceous ntiaj teb. Diatomaceous ntiaj teb, kuj hu ua Kieselguhr , lub teeb-xim, ntxeem tau, thiab friable sedimentary pob zeb uas yog tsim los ntawm siliceous shells ntawm diatoms, unicellular dej nroj tsuag ntawm microscopic loj.

Ib yam li ntawd ib tug yuav nug, qhov twg diatomite pom?

Nyob rau hauv lub tebchaws United States, loj deposits ntawm diatomite yog pom hauv California, Nevada, Washington thiab Oregon. Ntawm cov xeev no, California thiab Nevada tsim cov khoom loj tshaj plaws diatomite.

Koj yuav paub li cas yog tias koj muaj diatomite?

Diatomaceous ntiaj teb. Diatomaceous lub ntiaj teb los yog diatomite yog ib lub teeb-xim pob zeb sedimentary li ntawm siliceous shells (frustules) ntawm diatoms. Diatomaceous lub ntiaj teb yog pob zeb mos thiab friable. Nws tawm ntawm tes plua plav yog kov thiab muaj lub cev tsis taus zoo li nws muaj qhov muag muag thiab lub teeb yuag sab hauv.
