Many living things, including coral, clams, oysters, and snails, have shells or skeletons made of calcite. When these animals die, their shells pile up a sediment on the ocean floor. Over millions of years, these layers of sediment can grow to a depth of hundreds of meters. Slowly, the pressure of waveringly layers compacts the sediment .Some of the shells dissolve, forming a solution of calcite that seeps into the spaces between the shell fragments. Later, the dissolved material comes out of solution, forming calcite. The calcite cements the shell particles together, forming limestone.
What else can I help you with?
Is marble and limestone an example of a metamorphic rock and its parent rock?
Yes, marble is a metamorphic rock formed from limestone, which is the parent rock. This process occurs due to the recrystallization of minerals within the limestone under high pressure and temperature conditions.
Where is chert formed and under what conditions does it typically occur?
Chert is formed in sedimentary rocks, often in limestone or dolomite. It typically occurs in environments with low oxygen levels, such as deep ocean basins or shallow marine settings.
Can granite become marble?
No, granite cannot become marble. Granite and marble are two distinct types of rocks formed under different geological conditions. Granite is an igneous rock formed from the cooling of molten rock, while marble is a metamorphic rock formed from the recrystallization of limestone.
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.
What metamorphic rock will limestone turn into if it undergoes contact metamorphism?
If limestone undergoes contact metamorphism, it will typically turn into marble. Marble forms from the recrystallization of limestone under high temperature and pressure conditions.
What type of rock is formed by putting limestone under heat and pressure?
By the metamorphosis of limestone, marble is formed. By the thermal decomposition of limestone, quicklime is formed. Which process depends on the temperature and pressure.
what kind of rock is formed under clam water conditions near the shore?
Various sedimentary rocks but particularly Limestone and Sandstone.
Is marble and limestone an example of a metamorphic rock and its parent rock?
Yes, marble is a metamorphic rock formed from limestone, which is the parent rock. This process occurs due to the recrystallization of minerals within the limestone under high pressure and temperature conditions.
How is concrete formed from limestone?
concrete is formed from limestone by the combustion of the limestone (heating of the limestone)!
What does Limestone under certain conditions may undergo a metamorphosis?
Under certain conditions, limestone can undergo a metamorphosis where it is subjected to high temperatures and pressure, leading to recrystallization and the formation of marble. This process involves the restructuring of the mineral composition of the limestone into a new, more dense, and polished rock.
Is limestone rounded or jagged?
Depends on what kind of conditions it has been under.
Where is chert formed and under what conditions does it typically occur?
Chert is formed in sedimentary rocks, often in limestone or dolomite. It typically occurs in environments with low oxygen levels, such as deep ocean basins or shallow marine settings.
How do stalactites in limestone caverns most likely form?
The limestone caverns themselves are formed by groundwater gradually dissolving the limestone rock. In this process, some of the limestone is taken into solution, and under favourable conditions, it will form a drip on the roof of a cavern. This may eventually build to form a stalactite above, and perhaps also a stalagmite below it.

What is limestone's grain shape?
Limestone typically has a fine to medium-grained texture, with individual grains being mostly composed of calcium carbonate. The grains in limestone can have various shapes including rounded, angular, or elongated, depending on the specific conditions under which the rock was formed.
Can granite become marble?
No, granite cannot become marble. Granite and marble are two distinct types of rocks formed under different geological conditions. Granite is an igneous rock formed from the cooling of molten rock, while marble is a metamorphic rock formed from the recrystallization of limestone.
What part of the rock cycle is marble?
Marble is formed from the metamorphism of limestone, a sedimentary rock. This process involves the recrystallization of the calcium carbonate minerals present in limestone under high temperature and pressure conditions. Marble is an example of a metamorphic rock in the rock cycle.
