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.
