Equigranular texture refers to a rock texture where the mineral grains are of approximately equal size, indicating a uniform rate of cooling or crystallization. This uniformity suggests a stable environment during the rock's formation, often associated with plutonic or intrusive igneous rocks.

Equigranular texture

Rock texture refers to the size, shape, and arrangement of the grains or crystals within a rock, which provides insights into its history and formation processes. It is a crucial factor in determining the classification and identification of rocks, influencing their physical and mechanical properties.

Rock Texture

Mineral grains are the individual crystals that make up rocks and can vary in size, shape, and composition, influencing the rock's texture and properties. They are formed through various geological processes, including crystallization from molten rock, precipitation from solutions, or alteration of pre-existing minerals.

Uniform rate of cooling

Crystallization is a process by which a solid forms from a solution, melt, or more rarely, from a gas, where the atoms or molecules are highly organized into a structure known as a crystal. This process is widely used in chemical engineering and materials science to purify substances and to grow crystals for various applications, including pharmaceuticals and electronics.

Rock's formation

Plutonic igneous rocks

Intrusive igneous rocks form from magma that cools and solidifies below the Earth's surface, leading to the development of large crystals due to the slow cooling process. These rocks are a window into the Earth's interior, revealing the composition and conditions of the magma from which they formed.
