No. Contact metamorphism will most likely alter shale into hornfels. Phyllite is regionally metamorphosed slate, and slate is metamorphosed shale.

What causes metamorphic rock to change?
An increase in heat or pressure could cause further metamorphism.
What is parent rock of Muscovite schist?
Gneiss is a high grade metamorphic rock, the product of various rock types being exposed to intense pressures and heat under the surface of the Earth. Orthogneiss is a gneiss whose parent rock was igneous, and paragneiss is a gneiss whose parent rock was sedimentary.
When a rock changes due to the surrounding pressure on all sides what has occured?
Metamorphism from recrystallization could occur.
What is the texture of hornfels?
I too would like an answer to this question as it seems hornfels could be of varying grade dependant on the temperature. The facies of contact metamorphism progress in temperature at relatively low pressure from the Albite-Epidote Hornfels Facies to the Hornblende Hornfels Facies, to the Pyroxene Hornfels Facies. It seems that hornfels do have differant grades.
In which rock type are fossils usually founs?
Sedimentary, since the other two types involve extreme heat and/or metamorphism which could destroy any fossil evidence
What is the origin of phyllite?
Phyllite is a type of metamorphic rock that comes from adding heat, pressure, and/or chemically active fluids to slate. Slate is the parent, or originial, type of rock from which the phyllite forms. It could also be said that slate recrystallizes into phyllite. Slate is also a metamorphic rock that starts out as the sedimentary rock called shale. Therefore, phyllite comes from slate, which comes from shale. Phyllite is different from slate because it has been metamorphosed more. As a result, the straight lines/planes (called foliation) that slate breaks along, are absent in phyllite, which is distinctly wavy in appearance. If more metamorphism is applied to phyllite, it recrystallizes into schist.
What metamorphic rock will limestone turn into if it undergoes contact metamorphism?
I suppose it could be marble.
What causes metamorphic rock to change?
An increase in heat or pressure could cause further metamorphism.
Can slate turn into another metamorphic rock?
Yes, slate, which is a fine-grained metamorphic rock formed from the metamorphism of shale, can further undergo metamorphism to transform into another metamorphic rock. The process of changing one metamorphic rock into another is known as metamorphic progression or metamorphic differentiation. If slate undergoes increased heat and pressure over time, it can undergo further metamorphism and transform into a different type of metamorphic rock. The specific type of rock it may transform into depends on the intensity of the metamorphic conditions. For example, if the temperature and pressure increase significantly, slate might progress to phyllite, schist, and eventually, if conditions are extreme, it could transform into gneiss. Metamorphic rocks form through the alteration of existing rocks (igneous, sedimentary, or other metamorphic rocks) due to heat, pressure, or chemically reactive fluids over geological time. The process of metamorphism involves changes in mineral composition, texture, and structure.
What rocks are found during contact metamorphosis?
Contact metamorphism generally occurs relatively close to the surface in a zone of contact between an intruding magma body and the country rock, which could be a sedimentary, igneous, or previously metamorphosed rock. Hornfels is a common resultant contact metamorphic rock.
How could an igneous rock change to a metamorphic rock?
Under influence of pressure and temperature, a rock can change, the process is called deformation or metamorphism, the result is a metamorphic rock. This can happen to igneous rocks as well.
Takes place when magma intrudes rock?
It is called a dyke or dike, and could also be referred to as a discordant igneous intrusion.
Could cataracts change ability to wear old contact lens?
Yes
How can igneous rock disturb sedimentary rock layers?
Igneous rocks can disturb sedimentary rock layers and formations by their movement during ascent through such layer. when they make contact with this sedimentary rocks they could result to folding and/or metamorphism.
What country is Phyllite found in?
Rhyolite is an igneous, rock, of silica-rich composition (> 69% SiO2). The mineral assemblage is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2), Biotite and hornblende are common accessory minerals.
What is parent rock of Muscovite schist?
Gneiss is a high grade metamorphic rock, the product of various rock types being exposed to intense pressures and heat under the surface of the Earth. Orthogneiss is a gneiss whose parent rock was igneous, and paragneiss is a gneiss whose parent rock was sedimentary.
How can one rock be changed from one type of rock to another?
What would most usually happen would be that the rock would under-go something called metamorphism. This is when such natural forces- air, wind, rain, snow, etc.- would interfer with the growing & changing of the rock. E.g.- Sedimentary rock forms when sediment gets compacted & cemented together. If the rock does not get cemented together the "sediment" stays, well, sediment. The only way it could change is if metamorphism were to change its chemical composition, etc.
