Ocean Deposits - Learning with 3 Classifications & Mnemonics

Ocean Deposits Meaning

We can classify oceans based on sources, sediments and location of deposits.

Based on Source

On the basis of size of particles and density, Gravel, Sand, Silt, Clay and Mud pattern has been identified.

  • Lithogenous or Terrigenous⚹
  • Hydrogenous
  • Biogenous⚹
  • Red Clay
  • Cosmogenous
  • Volcanic Deposits
  • Inorganic Precipitates

Lithogenous Deposits

Biogenous Deposits

  • Calcareous Ooze
    • Globigerina Ooze
    • Pteropod Ooze
    • Coccolithophore Ooze
  • Siliceous Ooze
    • Diatoms: Derived from bio- decomposition of marine phytoplankton.
    • Radiolarian: Derived from bio- decomposition of radiolarian.
