Biogenic ooze, tseem hu ua biogenic sediment, txhua yam pelagic sediment uas muaj ntau tshaj 30 feem pua ntawm cov khoom siv pob txha . Cov sediments tuaj yeem ua los ntawm carbonate (los yog calcareous) ooze lossis siliceous ooze siliceous ooze Calcareous ooze yog ooze uas yog tsim los ntawm tsawg 30% ntawm calcareous microscopic shells-tseem hu ua kuaj-ntawm foraminifera, coccolithophores, thiab pteropods. … Siliceous ooze yog ooze uas muaj tsawg kawg yog 30% ntawm siliceous microscopic "plhaub" ntawm plankton, xws li diatoms thiab radiolaria. https://en.wikipedia.org › wiki › Pelagic_sediment

Yuav ua li cas rau sediment kom cais ib qho ooze?
Ooze, pelagic (dej hiav txwv) sediment uas tsawg kawg yog 30 feem pua yog tsim los ntawm cov pob txha seem ntawm cov kab mob microscopic floating. Oozes yog qhov yooj yim tso ntawm cov av nkos rau hauv av dej hiav txwv.
Dab tsi ntawm cov hauv qab no yog suav tias yog qhov chaw ntawm cov pob zeb biogenic?
Cov khoom xyaw tseem ceeb ntawm cov sediments biogenic yog li calcium carbonate, opaline silica, thiab organic teeb meem; thawj ob ntawm cov khoom xyaw no feem ntau nyob rau hauv cov duab ntawm microfossils nyob rau hauv dej hiav txwv tob (Funnell thiab Riedel, 1971; H. C. Jenkyns, hauv Kev Nyeem Ntawv, 1986).
Yuav ua li cas yog biogenic sediment tsim?
biogenous sediments yog tsim los ntawm insolubleseem ntawm cov kab mob nyob, xws li plhaub, pob txha, thiab cov hniav (Davis, 1985; Cronin et al., 2003). Lawv tuaj yeem muab faib ua peb pawg loj: calcareous biogenous sediments, siliceous biogenous sediments, thiab phosphatic biogenous sediments.
Dab tsi ua rau cov av nkos yog dab tsi ob hom ooze thiab qhov txawv ntawm lawv yog dab tsi?
Zoo cov sediments hu ua oozes.
muaj 2 yam ooze, calcareous ooze thiab siliceous ooze. Calcareous ooze muaj feem ntau ntawm calcium carbonate plhaub, thiab siliceous ooze muaj feem ntau ntawm silica plhaub. ntau lawv yuav yaj ua ntej mus txog hauv qab.

Nyob rau hauv cov pob zeb feldspar pob zeb hauv qhov twg?
Feldspars crystallize los ntawm magma raws li ob qho tib si intrusive thiab extrusive igneous pob zeb thiab tseem muaj nyob rau hauv ntau hom metamorphic pob zeb. Pob zeb tsim yuav luag tag nrho ntawm calcic calcic Raws li ib qho alkaline ntiaj teb hlau, calcium yog cov hlau reactive uas tsim cov txheej tsaus nti oxide-nitride thaum raug huab cua.
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Yuav ua kom cov pob zeb tshiab ua raws li cov pob zeb qub?
Cov cement hauv cov pob zeb sib xyaw tsis muaj cov khoom sib txuas ua ke - yog li thaum cov pob zeb tshiab ntxiv rau saum cov pob zeb uas twb muaj lawm, ob leeg yuav tsis koom ua ke. … Tus tshiab yuav tsis ua raws li qhov qub yam tsis muaj kev pab ntawm daim nplaum nplaum.
Lub sijhawm suav suav suav suav suav cov neeg txawv tebchaws?
Puas yog cov neeg tuaj txawv teb chaws tsis raug tso cai suav nrog cov neeg nyob hauv suav? Yog, txhua tus neeg (cov pej xeem thiab cov neeg tsis yog pej xeem) uas muaj chaw nyob ib txwm nyob hauv Tebchaws Meskas suav nrog cov neeg nyob hauv kev suav pej xeem.
Nyob hauv cov pob zeb tsis pom kev thiab cov pob zeb metamorphic?
Muaj peb hom pob zeb: igneous, sedimentary, thiab metamorphic. Igneous pob zeb tsim thaum molten pob zeb (magma los yog lava) txias thiab solidifies. … Metamorphic pob zeb tshwm sim thaum cov pob zeb uas twb muaj lawm hloov los ntawm tshav kub, siab, los yog reactive kua, xws li kub, mineral-laden dej.
