Quartzite--sandstone. Marble--limestone. Slate--shale. Gneiss--basalt or granite.
Quartz crystals typically grow hydrothermally, in hot, pressurized, silical solutions.
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.
The specific gravity of quartzite typically ranges from 2.65 to 2.75.
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.
A metamorphic rock changes from one form to another by intense heat or pressue. The parent rock, or protolith, is the rock that undergoes change. It can be any rock type, sedimentary, igneous, and even metamorphic.
A protolith of sandstone is a sedimentary rock made up of sand-sized mineral grains or rock fragments that have been compacted and cemented together over time. It can form from the erosion and deposition of pre-existing rocks like granite, quartzite, or basalt.
"protolith" refers to the original composition of an altered rock. for example, a basalt was the protolith to a rock thats presently a greenschist.
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.
peridotite
Quartzite is often referred to as "quartzite rock" or simply "quartzite." It is a metamorphic rock that is composed primarily of quartz grains.
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.
