Tichifunga nezvemashoko ari mundima inotevera anotaura nezvezvinhu zvakaita semarara, zvinhu zvakaita semarara zvinotsanangurwa sei?
Context:Siliceous ooze rudzi rwebiogenic pelagic sediment inowanikwa pasi pegungwa rakadzika. Mvura ine silica ndiyo isingawanzowaniki mumakungwa akadzika, uye inoumba inenge 15% yepasi pegungwa. MaOOZs anotsanangurwa semadhaka ane zvisaririra zvisingasviki 30% zvezvipembenene zvehutachiona hwepellagic. Mafuta ane silica anonyanya kugadzirwa nemapfupa ezvisikwa zvomugungwa zviduku zvikuru zvakadai sematomu nemapuraneti. Zvimwe zvinoriumba silicaous oozes pedyo nemakondinendi miganhu zvingasanganisira terrestrially yakabva silica particles uye siponji spicules. Siliceous oozes inoumbwa nemapfupa akagadzirwa neopal silica Si ((O2), kusiyana necalcareous oozes, iyo inogadzirwa nemapfupa e calcium carbonate organisms (i.e. coccolithophores). Silica (Si) chinhu chinokosha uye chinoshandiswazve zvinobudirira mumhoteredzo yegungwa kuburikidza nekutenderera kwe silica. Kure nenzvimbo dzevhu, kudzika kwemvura uye kubereka kwemakungwa zvose zvinhu zvinopesvedzera uwandu hweopal silica mumvura yegungwa uye kuvapo kwemvura ine silica.
MaOOZs anotsanangurwa semadhaka ane zvikamu makumi matatu kubva muzana zvezvisaririra zvezvipuka zviduku zvinogara mumvura.
