Marine organisms known as coccolithophores, which are single-celled algae with calcium carbonate plates, provide skeletal remains for chalk deposition. These organisms play a key role in the formation of chalk rocks through their accumulation of calcium carbonate plates in marine environments.
What else can I help you with?
What is sand bits of rock and the remains of organisms called?
Sand is composed of small fragments of rock and minerals, as well as the remains of various organisms such as shells, coral, and skeletal debris. The combination of these materials gives sand its characteristic texture and composition.
Is chalk made of microplankton?
No, chalk is primarily composed of calcium carbonate, a mineral made up of the skeletal remains of plankton and other marine organisms. Microplankton are tiny organisms found in the ocean, but they are not the main component of chalk.
Where did you probably find a deposit of limestone what type of setting did it form in?
Limestone is formed on the floor of ancient seas from the skeletal remains of marine organisms such as coral, forams and molluscs, etc.
Which sedimentary rock is made of Skeletal remains of organisms?
Limestones are sedimentary rocks made of skeletal remains. Limestones are recognizable because they react with Acid. Crystalline limestone are micro skeletons with large visible crystals. Micritic limestone is lithographic limestone and it is basically fine grained mud with micro-skeletons. Fossiliferous limestone is made with whole fossils in my experience mostly shells. Coquina is parts of skeletons pressed together. The difference between coquina and fossiliferous is that coquina doesn't have whole fossils. Lastly there is chalk. This is a lot of microorganisms remains pressed together.
What area specializes in the identification and examination of skeletal remains?
biology
Can shells become limestone?
They can, and do. Chalk and coquina are examples of limestone formed from skeletal or shell remains of marine organisms.
Do coral reefs have bones?
Yes. Coral is both the living and skeletal remains of Marine organisms. These in effect are the bones of the animals.
Where did sedimentary deposits come from?
Sedimentary deposits came from and still come from the weathering and erosion of surface features and from the deposition of the remains of organisms.
How is Dolomite formed in nature?
When magnesium carbonate replaces part of all the calcium magnesium in limestone skeletal remains marine organisms.
Is limestone made up of fragments of granitic and andesitic rocks?
No. Limestone is formed from precipitated calcite or from the shells or skeletal remains of marine organisms.
What is sand bits of rock and the remains of organisms called?
Sand is composed of small fragments of rock and minerals, as well as the remains of various organisms such as shells, coral, and skeletal debris. The combination of these materials gives sand its characteristic texture and composition.
What type of sedimentary rock forms from carbonate minerals precipitating from freshwater springs?
various types of limestone. . .including anything from skeletal remains of micro organisms and coral.
Is chalk made of microplankton?
No, chalk is primarily composed of calcium carbonate, a mineral made up of the skeletal remains of plankton and other marine organisms. Microplankton are tiny organisms found in the ocean, but they are not the main component of chalk.

Are coral reefs skeletal remains?
Basically...................yes.
What are the sediments in organic sedimentary rocks?
Skeletal and plant remains.
