The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock.
Is marble igneous or sedimentary or metamorphic?
Marble. When limestone, a sedimentary rock, gets buried deep in the earth for millions of years, the heat and pressure can change it into a metamorphic rock called marble.
What type of rock is marble?
metamorphic rock
Marble is a metamorphic rock. Metamorphic rocks are rocks that have undergone a change in composition due to intense heat and pressure.
Why is marble not a sedimentary rock?
Detailed Solution. The correct answer is Marble. Marble is a metamorphic rock that is metamorphosed limestone. Metamorphic rocks form when sedimentary, igneous, or pre-existing metamorphic rocks are changed by heat, pressure, and chemically reactive waters.
Why is marble A metamorphic rock?
Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.
What two sedimentary rocks can turn into marble?
Slate is another common metamorphic rock that forms from shale. Limestone, a sedimentary rock, will change into the metamorphic rock marble if the right conditions are met.
How is marble different from other rocks?
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
Is marble resistant to weathering?
Marble is composed of a mineral that is resistant to chemical weathering (quartz), whereas granite is composed of minerals less resistant to weathering (like calcite).
Is marble a hard or soft rock?
Marble is considered to be a strong, hard stone, even though its primary mineral, calcite, only has a Mohs hardness of 3. Marble can be scratched with a metal blade.
Is marble the hardest rock?
Answer: One of hardest rock found in India is metamorphic rock. India possesses a wide spectrum of dimensional stones that include granite, marble, sandstone, limestone, slate, and quartzite, in various parts of the country. The hardest rock in India is metaphoric rock which is formed by volcanic eruption.
Is slate a sedimentary rock?
Slate is a metamorphic rock of sedimentary origin. Is mainly composed of quartz, sericite and minerals of the chlorite group. Has been used as a construction material since the ancient Egyptians. Its colour depends on the mineral structure and size of the mineral grains that define its composition.
Is limestone a sedimentary rock?
Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris.
Is shale a sedimentary rock?
shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles. Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth. Shales are often found with layers of sandstone or limestone.
What is marble geology?
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite.In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.
Is marble a foliated metamorphic rock?
Figure 10.19 Marble is a non-foliated metamorphic rock with a limestone protolith.
What type of metamorphism is marble?
This is contact metamorphism. Some examples of non-foliated metamorphic rocks are marble, quartzite, and hornfels. Marble is metamorphosed limestone. When it forms, the calcite crystals tend to grow larger, and any sedimentary textures and fossils that might have been present are destroyed.
How marble rocks are formed?
How Marble is Formed? The formation occurs due to a reaction when limestone is subjected to intensive heat and pressure. The composition of marble consists of various minerals such as clay minerals, quartz, pyrite, micas, iron oxides and graphite, etc. but primarily the calcite.
What kind of rock is marble and granite?
Granite is an igneous rock, which means it was once molten and formed as it cooled deep within the earth. The minerals contained in granite usually appear as small flecks throughout the stone. Marble, on the other hand, was once limestone that changed due to intense heat and pressure.
Is Obsidian a sedimentary rock?
Obsidian is an igneous rock occurring as a natural glass that is formed by the rapid cooling of viscous lava from volcanoes.
Which is an example of sedimentary rocks?
Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock.
Is marble and limestone the same thing?
1. Limestone is a type of rock which is formed when mud, sand, and shells are deposited in oceans and lakes while marble is a type of rock which is formed by the recrystallization of limestone during the mountain-building process. 2. Both come in many colors and are used as building materials and other industrial uses.
