A rich assemblage of silicate-based minerals forming the igneous rocks that are solidified from magma. The faster the cooling the finer the crystals but the minerals are the same for a specific eruption or intrusion irrespective of cooling rate.
The process is called crystallization. It involves the cooling and solidification of magma, leading to the formation of minerals as atoms within the magma arrange themselves into a crystalline structure.

The rate of cooling of the magma determines the type of mineral formed by the magma or lava..
The type of mineral formed by cooling magma is primarily determined by the magma's chemical composition, particularly its silica content. As magma cools, different minerals crystallize at varying temperatures, a process known as fractional crystallization. Additionally, the cooling rate influences mineral formation; slower cooling allows larger crystals to grow, while rapid cooling results in smaller crystals or even glassy textures. Factors such as pressure and the presence of volatile substances can also impact mineral development.
Slow cooling of magma results in the formation of igneous rocks with coarse-grained textures, such as granite. The slower the cooling process, the larger the mineral crystals that can form within the rock. These rocks are commonly found in the continental crust.
TRUE, Cooling magma forms solid mineral phases
Yes. When magma cools and solidifies, mineral crystals are formed.
The rate of cooling of the magma primarily determines the mineral grain size in an igneous rock. Rapid cooling results in fine-grained rocks, while slow cooling allows for the formation of coarse-grained rocks. Additionally, the composition of the magma and the presence of nucleation sites can also influence the final grain size.
The formation of igneous rock involves two key processes: crystallization and cooling. Crystallization occurs when molten rock material, or magma, cools and solidifies, leading to the formation of mineral crystals. This process can happen either beneath the Earth's surface, resulting in intrusive igneous rocks, or on the surface following a volcanic eruption, leading to extrusive igneous rocks. The rate of cooling influences the texture and mineral composition of the resulting rock.
Yes. When magma cools and solidifies, mineral crystals are formed.
