What is siliceous ooze mostly made of?
It is a mixture of water and the silica shell remains of marine plankton.
How can you determine whether a spicule is calcareous or siliceous?
You can determine whether a spicule is calcareous or siliceous by performing a simple reactivity test: immerse the spicule in dilute hydrochloric acid (HCl). If it fizzes and dissolves, the spicule is likely calcareous (made of calcium carbonate). If there is no reaction, the spicule is likely siliceous (made of silica).
What is an example of a sedimentary rock that is biochemical (organic)?
Limestone and chalk are formed from organic material Limestone - Clastic shell fragments Chalk - Microscopic shells of calicum carbonate plates formed by single celled algaes Chert - Microscopic siliceous organisms, recrystallized silica
What type of rock is siliceous volcanic glass?
Siliceous volcanic glass is a type of rock known as obsidian. It forms when molten lava cools quickly, preventing the formation of distinct mineral crystals and resulting in a smooth, glassy texture. Obsidian is typically dark in color and is commonly used in tools and jewelry due to its sharp edges and attractive appearance.
Where is Siliceous sediment found?
Siliceous sediment is commonly found in areas with high biological productivity, such as offshore continental margins and deep-sea deposits. It can also be present in diatomaceous earth deposits and in shallow marine environments near volcanic islands.

What minerals is diatomaceous ooze skeleton composed of?
siliceous mineral
What are the different kinds of siliceous mineral?
quartz, feldspar, and mica.
What are slimy deposits at the bottom of the ocean?
The bottom of the ocean that is slimy is called a biogenous bottom. Some scientists refer to this kind of ocean bottom as an ooze. They are the result of a dominance of calcium shells and siliceous shell pieces which dissolve at the bottom of the ocean.
What are Calcareous and siliceous?
Calcareous refers to rocks or soils that contain a high proportion of calcium carbonate, while siliceous refers to those containing a high proportion of silica. Calcareous rocks are more associated with limestones and chalk, while siliceous rocks are more associated with materials like quartz and chert.
Which type of sediment is made up mainly of the shells of diatoms?
Siliceous
What is an example of an organize sedimentary rock?
Limestone and chalk are formed from organic material Limestone - Clastic shell fragments Chalk - Microscopic shells of calicum carbonate plates formed by single celled algaes Chert - Microscopic siliceous organisms, recrystallized silica
To which Limestone called siliceous Limestone?
The siliceous limestone that is commonly found is known as chert or flint. It is a type of limestone that has a high silica content, giving it a distinctive appearance and often used for various purposes such as construction, decoration, and tool-making.

Which type of sediments is made up mainly of shells of diatoms and radiolarians?
Siliceous
