WebIgneous rock texture indicates the rate of magmatic cooling. Crystallization takes place either slowly in deeply buried intrusions called plutons, or rapidly at the earth's surface where magma has been extruded as lava by volcanic activity. Igneous rocks are therefore classified as either intrusive (plutonic) or extrusive (volcanic). In geology, texture or rock microstructure refers to the relationship between the materials of which a rock is composed. The broadest textural classes are crystalline (in which the components are intergrown and interlocking crystals), fragmental (in which there is an accumulation of fragments by some physical process), aphanitic (in which crystals are not visible to the unaided eye), and gl… iphone xr trendyolWebSalt is sometimes crystallized to produce flake-shaped grains which have a unique texture or intensity of flavor.
