What are meta metamorphic rocks?
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
What is Shale’s parent rock?
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.
What type of rock is Geiss?
Gneiss is a type of metamorphic rock that forms when a sedimentary or igneous rock is exposed to extreme temperatures and pressure. When this happens, virtually no traces of the original rock remain. Gneiss rocks are characterized by their arrangement of minerals into long bands.
What type of rock is Blueschist?
Blueschist ( /ˈbluːˌʃɪst/), also called glaucophane schist, is a metavolcanic rock that forms by the metamorphism of basalt and rocks with similar composition at high pressures and low temperatures (200–500 °C (392–932 °F)), approximately corresponding to a depth of 15–30 km (9.3–18.6 mi).
What does the prefix meta and the root morph convey in the word metamorphic?
metamorphic Add to list Share. In geology, metamorphic describes a specific process that some rocks undergo when heat and pressure changes them. The Greek metamorphoun, “to transform,” is from meta, “change,” and morphe, “form.”
Which rock can form in a contact metamorphic zone?
The original rock with thermal contact metamorphism is mainly mudstone, carbonate rock, clastic rock, and igneous rock that can form different thermal contact metamorphic rock types.
What is limestone parent rock?
Definition. Limestone is the parent rock of marble.

Is blueschist metamorphic?
THE high-pressure, low-temperature metamorphic rocks known as blueschists have long been considered to form in subduction zones, where the descent of a relatively cold slab leads to the occurrence of unusually low temperatures at mantle pressures.
