CHAPTER 5 VOCAB: BIOGENEOUS – pg 135 Hydrogenous – Minerals that have precipitated directly from seawater. Sources are rock & sediment, fresh crust leaching at oceanic ridges, material from hydrothermal vents PG 135, 142 siliceous ooze – Ooze composed mostly of the hard remains of silica-containing oraganisms. Calcium containing material, most common low depths. About 14% or the surface of the deep ocean flr is covered by it. PG 141 142 Calcareoius Oooze – ooze composed mostly of the hard remains of organisms containing calcium carbonate. Coccolithophores – tiny algae. Remains compressed & lithified to form White Cliffs of Dover in England. PG 141 142 Diatoms – Single celled phytoplankton. Contribute to biogenous sediements. siliceous ooze is formed from hard parts of another amoeba like animal from single celled algae called DIATOM. After diatoms die its shell will also dissolve back into seawater. Oozes are most common at high latitudes. PAGE 142 Forminifera – Calcareoius ooze forms mainly from shells of amoeba like foraminifera. PG 141 Radiolarian
