globigerina ooze
Quick Summary
Globigerina ooze is a type of pelagic sediment found on the ocean floor, primarily composed of the shells of microscopic, floating organisms called globigerinae. These organisms are a type of foraminifera, which are single-celled marine organisms with calcareous shells.123
Globigerina ooze is a calcareous ooze, meaning its skeletal remains are made of calcium carbonate. It is the most widespread type of ooze, found in both the Atlantic and Indian Oceans, typically at depths between 1,000 to 3,000 feet. This sediment forms in areas far from land, where the deposition of these tiny shells is not obscured by land-derived sediments. Holocene-age globigerina ooze can sometimes appear slightly pinkish due to trace iron oxides, distinguishing it from older, grayer deposits.214

Thus, the calcareous oozes include globigerina ooze, containing the shells of planktonic foraminifera, and pteropod ooze, made up chiefly of the shells of pelagic mollusks. The siliceous oozes include radiolarian ooze, comprising essentially brown clay with more than 30 percent of the skeletons of warm-water protozoa, and diatom ooze, containing…
