Porphryitic igneous rock is composed of phenocrysts embedded in a finer matrix.
*fine-grained *coarse-grained
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.
An igneous rock that has two or more different sized crystals due to a change in cooling rate is called a porphyritic rock. This rock typically has larger crystals (phenocrysts) embedded in a fine-grained matrix, which indicates that the rock underwent a two-stage cooling process.
Rough and smooth would be the two basic textures.
The process of matching rock layers in two different places is called correlation. Geologists study the lithology, fossils, and relative positions of rock layers to determine if they are the same age and originated from the same geological event. Correlating rock layers helps geologists understand the Earth's history and past environments.

The rocks may have different textures
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
There are two types of cheesecakes: Chilled and baked. They use different recipes and have different textures. Both are good.
Textures has two syllables.
The two main textures of rock are intrusive (coarse-grained) and extrusive (fine-grained). Intrusive rocks form underground and have larger crystals due to slower cooling, while extrusive rocks form on the Earth's surface and have smaller crystals due to rapid cooling.
The displacement between two bodies of rock is called the fault.

It is an example of extrusive igneous rock.
stress that pushes a mass of rock in two opposite directions is called shearing
