Siliceous oozes predominate nyob rau hauv ob qhov chaw hauv dej hiav txwv: ncig Antarctica thiab ob peb degrees ntawm latitude sab qaum teb thiab sab qab teb ntawm Equator. Nyob rau hauv siab latitudes cov oozes suav nrog feem ntau lub plhaub ntawm diatoms.
Cov txheej txheem siliceous ooze tsim nyob qhov twg?
Siliceous ooze yog ib hom biogenic pelagic sediment nyob ntawm dej hiav txwv tob. Siliceous oozes yog qhov tsawg tshaj plaws ntawm cov dej hiav txwv sib sib zog nqus, thiab ua rau kwv yees li 15% ntawm cov dej hiav txwv hauv av.
Yuav ua li cas thiaj tsim siliceous ooze?
Nyob rau thaj chaw muaj zaub mov zoo xws li thaj chaw nyob hauv cheeb tsam polar thiab equatorial, silica-raws li cov kab mob xws li diatoms lossis radiolarians yuav ua tus thawj, ua rau cov sediments ntau dua los ua ib qho siliceous-based ooze.
Qhov twg koj xav kom pom qhov muaj siab ntawm siliceous ooze?
Feem ntau, siliceous ooze tsuas yog nyob rau hauv thaj chaw ntawm cov khoom siv dej lom neeg siab heev (xws li txoj kab nruab nrab thiab lub ncov qaumteb qabteb thiab thaj chaw ntug dej hiav txwv), qhov tob ntawm cov dej hiav txwv yog tob tshaj qhov CCD.
Qhov twg thaj chaw diatom ooze tshwm sim?
Ib txoj siv ntawm diatom ooze tshwm sim nruab nrab latitudes 45 ° thiab 60 ° S thiab thoob plaws North Pacific, nruab nrab ntawm Nyiv thiab Alaska Calcareous globigerina ooze tshwm sim nyob rau hauv qhov ntiav ntiav ntawm sab qab teb Pacific, lub zog tawg ntawm cov dej hiav txwv ntawm qhov tob tob txaus kom yaj cov khoom siv calcareous…

Calcareous ooze dominates dej hiav txwv sediments. Cov kab mob uas muaj calcium-raws li cov plhaub xws li foraminifera muaj ntau thiab nthuav dav thoob plaws ntiaj teb cov dej hiav txwv bass - ntau dua li cov kab mob silica . calcareous ooze feem ntau yuav pom nyob qhov twg?
Calcareous ooze thiab siliceous ooze txawv li cas?
Siliceous ooze yog ib hom biogenic pelagic sediment nyob rau hauv dej hiav txwv tob. … Siliceous oozes yog tsim los ntawm cov pob txha ua los ntawm opal silica Si(O 2), as opposed to calcareous oozes, uas yog tsim los ntawm skeletons ntawm calcium carbonate kab mob (piv txwv li coccolithophores).
