What is siliceous ooze mostly made of?
It is a mixture of water and the silica shell remains of marine plankton.
What type of rock is siliceous volcanic glass?
Siliceous volcanic glass is also known as obsidian.
What is the chemical difference between radiolarian and foraminifera?
The chemical differences between Radiolarian and Foraminifera are in the types of shell casts they have developed. Radiolarians have siliceous shells, whereas Foraminifera have calcareous shells.
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
In what phase can you find iron and nickel in the mantle?
The mantle does not contain free Iron or Nickel. It is made of siliceous minerals.
What is siliceous ooze mostly made of?
It is a mixture of water and the silica shell remains of marine plankton.
What is siliceous ooze mostly composed of what?
It is a mixture of water and the silica shell remains of marine plankton.
What type of rock is siliceous volcanic glass?
Siliceous volcanic glass is also known as obsidian.
What are Calcareous and siliceous?
biogenous
What is the chemical difference between radiolarian and foraminifera?
The chemical differences between Radiolarian and Foraminifera are in the types of shell casts they have developed. Radiolarians have siliceous shells, whereas Foraminifera have calcareous shells.
What is the difference between calcareous ooze and siliceous ooze?
Calcareous ooze is composed of calcium carbonate, while siliceous ooze is made from silicon oxide.
To which Limestone called siliceous Limestone?
The rock tripoli is considered a siliceous limestone, as most of the calcium carbonate has been weathered out or baked out by proximity to a plutonic intrusion.
Which type of sediment is made up mainly of the shells of diatoms and radiolarians?
We know that limestone is made up of those things, and some others. We also know that chalk, a kind of limestone, is composed mainly of tiny shells made of a mineral called calcite.
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 minerals is diatomaceous ooze skeleton composed of?
siliceous mineral
What are the different kinds of siliceous mineral?
quartz, feldspar, and mica.
Which type of sediment is made up mainly of the shells of diatoms?
Siliceous
