fine grained extrusive rocks can contain Potassium and Plagioclase Feldspar, Quartz, Biotite, Amphibole, Pyroxene and Olivine. these are all the choices for every igneous rocks
No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.
Basalt is known as a type of rock. This rock is a dark-colored and fine grained.
Fine-grained sedimentary rocks are classified by grain size and range from those composed of sub-microscopic particles (chert) to those with sand-sized particles (sandstone).
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.

rock.A2. A fine-grained sedimentary rock.
Traprock is any of the various, dark-colored, fine-grained igneous rocks, such as basalt, that is primarily used as crushed rock for road construction. Granite rock on the other hand, is any of the various light-colored, coarse-grained igneous rocks that is used in building construction and architectural design.
