What rock is formed when existing rock is altered by conditions of extreme pressure and temperature?
Metamorphic rock is formed when existing rock is altered by conditions of extreme pressure and temperature. This alteration can occur deep within the Earth's crust or during tectonic activity. Examples of metamorphic rocks include marble, slate, and schist.
Is calcareous tufa a metamorphic rock?
No, calcareous tufa is not a metamorphic rock. It is a sedimentary rock formed from precipitation of calcium carbonate from bodies of water. Metamorphic rocks are formed through the alteration of existing rocks under high temperature and pressure conditions.
Metamorphic rocks with the same mineral assemblages belong to the same?
metamorphic facies. This indicates that these rocks formed under similar pressure and temperature conditions despite coming from different locations.
What are metamorphic facies?
Metamorphic facies are groupings of mineral assemblages that form under specific temperature and pressure conditions during the metamorphism of rocks. They provide a way to classify and understand the conditions under which metamorphic rocks formed. There are several types of metamorphic facies, such as greenschist, amphibolite, and eclogite facies, each representing different ranges of temperature and pressure.
What is a metamorphic rock formed from limestone?
A metamorphic rock formed from limestone is known as marble. Marble is created when limestone undergoes intense heat and pressure over time, causing its minerals to recrystallize and form a new, harder rock with a characteristic crystalline texture.
Where and under what conditions are metamorphic rock formed?
Heat and pressure deep beneath Earth's surface can change any rock into metamorphic rock

Which metamorphic rocks are massive and lacking banding?
Marble and quartzite are examples of massive metamorphic rocks that lack banding. Marble is formed from the metamorphism of limestone, while quartzite is formed from the metamorphism of sandstone. Both rocks typically have a uniform composition and lack the distinct layering or banding that is characteristic of other metamorphic rocks.
Are rubies formed in magma?
No, rubies are formed in metamorphic rocks under high pressure and temperature conditions. They are made of the mineral corundum (aluminum oxide) that has been exposed to these conditions, often found in marble deposits.
Can metamorphic rocks turn into diamonds?
Yes, diamonds are formed deep underground under high pressure and temperature conditions. Metamorphic rocks are one of the rock types where diamonds can be formed, typically through the process of metamorphism of carbon-bearing rocks like shale or limestone. However, not all metamorphic rocks can turn into diamonds as specific geological conditions are required for their formation.
Is labradorite igneous metamorphic or sedimentary?
Labradorite is an igneous rock. It is formed from the slow cooling of magma deep within the Earth's crust, resulting in the development of its characteristic iridescent colors.
Is uvite formed by sedimentary metamorphic or igneous?
metamorphic
Gneiss is formed from what rock?
Gneiss is formed from the metamorphism of pre-existing rocks, such as granite or shale, under high temperature and pressure conditions. This process causes the minerals in the original rock to reorganize into distinct bands or layers, giving gneiss its characteristic banded texture.
