The type of rock that typically has discrete sections of minerals in coarse grains is called a "granite." Granite is an igneous rock composed mainly of quartz, feldspar, and mica, and its coarse-grained texture allows individual mineral crystals to be easily distinguished. The slow cooling of magma beneath the Earth's surface facilitates this coarse crystallization. Other examples of coarse-grained rocks include diorite and gabbro, which have similar textures but different mineral compositions.
The type of rock that features discrete sections of minerals in coarse grains is called a pegmatite. Pegmatites are igneous rocks characterized by their exceptionally large crystals, often exceeding one centimeter in diameter, and they typically form in the late stages of magma crystallization. This results in a coarsely grained texture where individual mineral components can be easily distinguished.
Millets are referred to as coarse grains due to their relatively larger seed size and tougher husk compared to finer grains like wheat and rice. They are often less refined, retaining more of their nutrients, fiber, and minerals, which contribute to their classification as coarse. Additionally, their hardiness and adaptability to diverse growing conditions make them more resilient, further emphasizing their classification as coarse grains.
The mineral that can have coarse grains or six-sided crystals is quartz. Quartz commonly forms in hexagonal crystal structures and can appear in various grain sizes, ranging from fine to coarse. Its diverse appearance is due to the different environments in which it crystallizes, making it one of the most abundant minerals in the Earth's crust.
Rocks with coarse texture typically form deep below the Earth's surface in the magma chamber of a volcano or in the mantle. As the molten rock cools slowly over time, large mineral grains have the opportunity to grow, resulting in a coarse texture. This process allows for the formation of rocks like granite or pegmatite.
Quartzite is typically coarse-grained, with individual grains visible to the naked eye. This is because quartzite is formed by the metamorphism of sandstone, where the original sand grains recrystallize into larger grains.

Fine grains are harder than coarse grains
Millets are known as coarse grains that can be grown on less fertile and sandy soil.
Jowar, Bajra, Ragi like millets is known as coarse grains.
An intrusive rock typically contains coarse-grained minerals, such as feldspar, quartz, and mica. These minerals were able to grow larger due to the slow cooling process of intrusive rocks beneath the Earth's surface.

Visible crystals or grains would be referred to as a coarse grained texture.
rocks with grains that can be identified with naked eye
Quartzite is typically coarse-grained, with individual grains visible to the naked eye. This is because quartzite is formed by the metamorphism of sandstone, where the original sand grains recrystallize into larger grains.
Metamorphic rocks can have various types of minerals, such as quartz, feldspar, mica, and amphibole, which form grains within the rock. These grains can be elongated or flattened, depending on the degree of metamorphism the rock has undergone. The size, shape, and alignment of these grains provide valuable information about the rock's history and the conditions under which it formed.
