Coarse grain
Granite is considered a coarse grained rock.
fine grained or coarse grained
The grain of an intrusive rock is typically coarse due to the slow cooling process underground, allowing large crystals to form. This coarse grain size is a distinguishing feature of intrusive rocks compared to extrusive rocks, which cool quickly on the Earth's surface and have fine-grained textures.
Three characteristics of a rock's grain include size (fine, medium, coarse), shape (angular, rounded), and sorting (well-sorted, poorly sorted). These characteristics can provide information about the rock's origin and history.
true mf
The name applied to a coarse-grained felsic igneous rock is granite. It is composed mainly of quartz, feldspar, and mica minerals. Granite is commonly used as a building material due to its durability and aesthetic appeal.

fine grained or coarse grained
No. They are large and visible to the unaided eye.
Large crystals with a coarse crystal grain texture.
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
The grain of an intrusive rock is typically coarse due to the slow cooling process underground, allowing large crystals to form. This coarse grain size is a distinguishing feature of intrusive rocks compared to extrusive rocks, which cool quickly on the Earth's surface and have fine-grained textures.
When all the grains in a rock are large and easy to see, the rock is described as having a coarse texture. This typically indicates that the rock formed from slowly cooling magma deep beneath the Earth's surface.
The texture of the rock product of slow cooling magma is referred to as coarse grained.
The term felsic des derived from feldspar and silica, which are the primary components of felsic rock.
