What rock type has large crystals in no paticular pattern?
Non-foliated metamorphic rock is composed of non-layered visible mineral crystals.
What are the large crystals called in an igneous rock mostly composed of a finer grained matrix?
The larger crystals or masses of larger crystals are called phenocrysts.
Is metamorphic rock crystalline or composed of crystals?
Metamorphic, igneous, and sedimentary rock are all composed of crystals, which vary greatly in size.
What kind of igneous rock usually contain large crystals?
Intrusive or granite.
Does melted rock that cools quickly result in igneous rock with large mineral crystals?
No, melted rock that cools quickly result in igneous rock with large minerals because large crystals take time to form and the rocks that usually have them are the ones that were formed inside the earth.
What kind of rock formation is sometimes filled with crystals?
Geodes are rocks that are lined or filled with crystals. Pegmatites are rock formations that often exhibit extremely large crystals. Just a note--all rocks are composed of mineral crystals, with few exceptions. The crystals in some, however are just too small to see.
What are large crystals known as?
A rock with large crystals indicates that the rock cooled slowly. It is referred to as a phaneritic texture when a rock forms this way.
How do small crystals form?
Answer: Crystals usually form from molten rock as the molten rock gradually cools. If the molten rock cools very rapidly, then either small crystals form or no crystals form. An example of this is when lava is ejected from a volcano. If molten rock cools slowly, then large crystals can form. This happens usually when the molten material is very deep in the Earth. Examples of these types of crystals are diamonds, emeralds, rubies, etc.
A rock with large crystals surrounded by small crystals is called?
porphyry
Large size crystals are known as phaneritic what?
A rock with large crystals indicates that the rock cooled slowly. It is referred to as a phaneritic texture when a rock forms this way.
Can crystals form near Earth's upper mantel?
Absolutely. The mantel is composed of rock. Rock is composed of minerals. Minerals, by definition, have a crystalline structure.
What igneous rock does not have large crystals?
sedimantry
