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.
Stromatolites are formed by the layering of cyanobacteria and sediment particles, primarily calcium carbonate, over time. The cyanobacteria trap and bind sediment, causing layers to build up and form a characteristic dome-like structure visible in stromatolites.

What was responsible for the accumulation of limestone deposits known as stromatolites?
Stromatolites are formed by the growth of layer upon layer of cyanobacteria (formerly known as blue-green algae) on shallow marine or freshwater environments. The cyanobacteria trap and bind sediments, leading to the formation of limestone deposits over time.
What do limestone deposits tell about there environment they were formed in?
Limestone deposits suggest that they were formed in a marine environment, typically in shallow, warm, and calm waters where the accumulation of calcium carbonate skeletons and shells of marine organisms was prevalent. The presence of fossils within limestone can indicate the past biodiversity and environmental conditions of the area where the deposits formed. Additionally, the purity and composition of the limestone can provide clues about the depositional processes and the source of the materials.
A sedimentary rock that is sometimes formed by deposits of shell fragments?
Limestone is a common sedimentary rock formed from the accumulation of shell fragments, coral, and other marine organisms. Over time, these organic materials can become compressed and cemented together to create a solid rock formation.
What is rocks formed from sediment deposits?
Rocks formed from sediment deposits are called sedimentary rocks. They are formed from the accumulation and lithification of sediment, which can include fragments of pre-existing rocks, minerals, and organic material. Examples include sandstone, shale, and limestone.
Is a limestone made from precipitated calcite clastic?
No, limestone made from precipitated calcite is not considered clastic. Clastic rocks are formed from fragments of pre-existing rocks, while limestone is formed through the accumulation of calcite deposits from the precipitation of calcium carbonate.

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.
WHAT ARE two types of sedimentary rocks and describe what they are made from?
Two types of sedimentary rocks are sandstone and limestone. Sandstone is made from grains of sand that have been compacted and cemented together, while limestone is primarily made from the accumulation of the shells and skeletons of marine organisms.
Which of the mineral has most widespread deposits in pakistan?
Limestone
Can you find gold in limestone caves?
Gold is typically not found in limestone caves. Gold is formed through geological processes such as hydrothermal deposition and erosion, while limestone is a sedimentary rock formed from the accumulation of calcium carbonate. However, gold can be found in certain types of geological formations such as quartz veins and placer deposits.
Do some limestone have pieces of broken seashells that you can see?
Yes, some limestone contains visible pieces of broken seashells. Limestone is formed from the accumulation of calcium carbonate deposits, which can include fossilized remains of marine organisms like shells. These fossilized shells can be visible in the rock as distinct shapes or patterns.
Where is limestone found in nature?
Limestone is commonly found in nature in areas with ancient sea beds, such as marine environments and seabeds. It is formed from the accumulation of marine life remains like shells and coral that undergo compression over time. Limestone can also be found in caves and cliffs formed by the erosion of these marine deposits.
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.
