• How long do they take to settle?
Biogenous• Are source of oceanic hydrocarbons
Lithogenous and BiogenousDeep ocean floor sediments (beyond continental margin)
Clay is most abundant in Pacific
CaCO3 ooze most abundant in Atlantic
CaCO3 ooze most abundant in Indian
World: Oceans: ~ 48% CaCO3, 38% clay, 14% silica ooze
