Porous and Non-Porous
It is an example of extrusive igneous rock.
The texture would reflect the degree and type of metamorphism which had led to its formation. Rock can experience various stages of metamorphism in its evolution depending mostly on changes in heat or pressure. Texture is also dependent on the composition of the protolith, or parent rock.
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.
The rocks may have different textures
The two main families of rock forming minerals are silicate minerals and non-silicate minerals. Silicate minerals are the most abundant and include minerals such as quartz and feldspar, while non-silicate minerals include groups like carbonates and sulfates.
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.

Textures has two syllables.
Rough and smooth would be the two basic textures.
