What is responsible for the accumulation of limestone deposits known as stromatolites?
Sediment trapping and the growth and metabolic activities of matlike cyanobacteria colonies contribute to the creation of stromatolites. Small particles of calcium carbonate settle onto the sticky matlike colonies of cyanobacteria forming thin layers of calcium carbonate. The cyanobacteria then build up over the calcium carbonate layer (so as not to be buried and killed) producing another sticky surface where more fine particles of calcium carbonate can be trapped.
A sedimentary rock that is sometimes formed by deposits of shell fragments?
A sedimentary rock that is sometimes formed by deposits of shell fragments is LIMESTONE!!
What are massive deposits of limestone?
Massive deposits of limestone are the result of calcium carbonate deposition, either precipitated or organically produced in a marine environment.
What can limestone deposits tell scientists about the environment in which they evolved?
ballls
What do limestone deposits tell about there environment they were formed in?
The environment was a tropical ocean

When is Limestone formed?
Limestone is formed mainly through the accumulation of marine shells and coral skeletons over millions of years. These deposits undergo compaction and cementation to form solid limestone rock. The process is typically associated with areas where there was once a shallow sea or ocean.

Which of the mineral has most widespread deposits in pakistan?
Limestone

How can limestone deposits be used to learn about earth's history?
yes
Are limestone deposits are often evidence of ancient tropical seas?
Many geologists believe that limestone deposits on land exist where ancient seas used to be. The moisture, over many centuries, created limestone.

A rock formed by deposits of shell fragments?
A rock formed from deposits of shell fragment is Limestone.
What evidence do limestone deposits from coral reefs provide about Earth's history?
Limestone deposits that began as coral reefs provide how plate motions have changed Earth's surface. These deposits also provide evidence of past environments.
