Can metamorphic rocks be formed by the formation of minerals from a solution?
Rock formed from minerals that precipitate from saturated solutions are called chemical sedimentary rocks, such as rock salt and rock gypsum.In some metamorphic rock processes, the loss of fluid due to heat and pressure can cause the transformation of some minerals into other minerals, but this is a different process than that which is causing precipitation from a saturated solution. In retrograde metamorphism, hydration (the addition of water) can also cause the transformation of some minerals.
How garnet break?
Garnet can break under excessive force, impact, or pressure. As a relatively hard and durable gemstone, garnet is typically resistant to scratching and chipping in normal wear. However, sharp blows, extreme temperature changes, or sudden impacts can cause it to fracture or break.
Does pressure usually causes long minerals crystals to align?
Yes, pressure can cause long mineral crystals to align in a process known as foliation. This alignment occurs in metamorphic rocks under directional pressure, which causes the minerals to grow in a preferred orientation parallel to the direction of pressure.
What metamorphic rock is made from schist?
Gneiss is a metamorphic rock formed when intense heat and/or pressure is applied to it's parent rock schist.
Which phenomenon leads to the formation of metamorphic rocks?
Metamorphic rocks are formed when existing rocks undergo intense heat, pressure, or chemical changes within the Earth's crust. These changes cause the minerals in the rocks to reorganize and form new structures, resulting in the creation of metamorphic rocks.
Are metamorphic rocks formed by some combination of heat pressure and mechanical activity?
Yes, metamorphic rocks are formed by the combination of heat, pressure, and sometimes chemical reactions acting on existing rock types. These processes cause the minerals within the rocks to recrystallize and reorganize, resulting in the formation of new minerals and textures.

What b do minerals sometimes form in metamorphic rock?
Minerals in metamorphic rocks can form due to changes in temperature and pressure, which cause existing minerals to recrystallize or new minerals to grow. The specific minerals formed depend on the original composition of the rock and the conditions under which the metamorphic process occurred.
How do high temperatures and pressures cause fossils to change into minerals or rocks to change their nature?
The changes take place because of recrystallization or realignment of existing minerals, or creation of minerals from existing assemblages that that can only be formed under certain specific ranges of temperature or pressure.
During metamorphism of granite into gneiss what happens to the minerals?
With the extreme heat and pressure causing the metamorphism into gneiss, the constituent minerals recrystallize into bands, usually alternating from light colored to dark, perpendicular to the direction of the pressure which is being applied. The exact cause of the banding is not fully understood at this time.
What two forces cause the formation of metamorphic rock?
Heat and pressure.
Metamorphic rock can be formed from sedimentary rocks by the activity of?
Metamorphic rock can be formed from sedimentary rocks through the activity of heat and pressure. The intense heat and pressure cause the minerals in the sedimentary rocks to recrystallize, resulting in a new, more compact rock with different properties.
How is phyllite formed?
Phyllite is formed from the metamorphism of shale or mudstone. During this process, the minerals in the original rock recrystallize and align in a parallel structure, giving phyllite its characteristic foliated texture. The increased heat and pressure cause the minerals to reorganize, forming a fine-grained texture with a silky sheen.
What is formed from shale exposed to great pressure?
Shale exposed to great pressure can form slate, a fine-grained metamorphic rock. The intense pressure and heat cause the clay minerals in the shale to recrystallize, resulting in a denser and more durable rock with distinct foliation.
What are rocks made when other rocks are subjected to intense pressure and heat?
Rocks are formed when other rocks are subjected to intense pressure and heat through the process of metamorphism. This process can cause the original minerals and textures of the rock to change, resulting in the formation of metamorphic rocks such as marble, schist, and gneiss.
How is a hydrothermal vent formed?
A hydrothermal vent is formed when seawater seeps into cracks in the oceanic crust, gets heated by magma underneath, and then rises back to the seafloor. The high temperatures and pressure at these vents cause minerals and metals to dissolve in the hot water, creating unique underwater ecosystems.
