What is the difference between calcareous ooze and siliceous ooze?

Calcareous ooze is a type of deep-sea sediment primarily composed of the mineral calcite, which is derived from the shells of marine organisms like foraminifera and coccolithophores. Siliceous ooze, on the other hand, is composed of silica-based minerals such as opal, originating from the silica skeletons of diatoms and radiolarians. The main difference between the two lies in the mineral composition, with calcareous ooze being calcite-based and siliceous ooze being silica-based.
