WHAT IS The original rock before it metamorphoses?
The original rock before it undergoes metamorphism is called a protolith. This protolith can be any type of pre-existing rock, such as shale, sandstone, or granite, that is subjected to heat, pressure, and chemical changes to form a metamorphic rock.
What is the meaning of Protolith in geology?
"protolith" refers to the original composition of an altered rock. for example, a basalt was the protolith to a rock thats presently a greenschist.
What rock type is a protolith of a metamorphic rock?
The protolith of a metamorphic rock can be any pre-existing rock type, such as shale, limestone, basalt, or granite. The type of metamorphic rock that forms from a protolith depends on factors like temperature, pressure, and the mineral composition of the protolith.
What is an example of parent rock?
It means the rock that a small piece broke off from. Outside our local library is a boulder quite different from our local sandstone. It is labelled as 'an erratic block of andesitic agglomerate' which broke off 'from the parent rock in Cumbria some millions of years ago'. It was carried about 120 miles by a glacier.
What original rock undergoes metamorphic changes?
The original rock that undergoes metamorphic changes is called a parent rock or protolith. These rocks, such as shale, sandstone, and limestone, are subjected to heat and pressure deep within the Earth, causing their mineral composition and texture to change, resulting in the formation of metamorphic rocks.
What is the protolith of a quartzite?
The protolith of a quartzite is a sedimentary rock called sandstone. Quartzite forms when sandstone undergoes metamorphism, typically due to high heat and pressure, causing the quartz grains in the sandstone to recrystallize and merge together.
What is the protolith of hornfels?
The protolith of hornfels is typically a fine-grained sedimentary rock such as shale or mudstone. These rocks undergo metamorphism due to high temperatures and pressure, resulting in the formation of hornfels.

What the protolith is of serpentine?
peridotite
What are the protoliths of Schist and Anthracite coal?
The protolith of schist is typically shale or slate, which undergoes metamorphism to form schist. The protolith of anthracite coal is primarily bituminous coal, which is subjected to higher temperature and pressure conditions during metamorphism to convert into anthracite coal.
What was formed?
The protolith of marble was limestone or dolomite.
What was formed from?
The protolith of marble was limestone or dolomite.
What is the protolith of phyllite?
The protolith of phyllite is shale or mudstone that has been subjected to low-grade metamorphism. This metamorphic process causes the rock to recrystallize, resulting in a foliated texture with fine-grained mica minerals like muscovite and chlorite.
