When all grains in a rock are large and easy to see, the rock is described as coarse-grained.
When all grains in a rock are large and easy to see, the rock is described as coarse-grained.
When all the grains in a rock are large and easy to see, the rock is described as "coarse-grained." This texture indicates that the rock has undergone a slower cooling process, allowing larger crystals to form. Coarse-grained rocks are often associated with igneous rocks, such as granite, where the individual mineral grains can be distinctly identified.
Coarse grain
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.
When all grains in a rock are large and easy to see, the rock is described as coarse-grained.
When all the grains in a rock are large and small to see, the rock is described as having a bimodal grain size distribution. This means that the rock contains both large and small grains, with little to no medium-sized grains present.
Texture.
This describes an igneous rock with a coarse-grained texture, likely formed deep within the Earth's crust where cooling is slower, allowing time for large mineral grains to form. This type of rock is typically intrusive, such as granite or diorite, and is characterized by its visibly distinct mineral grains.
The word that describes the shapes and sizes of grains in a rock is "texture." Texture refers to the arrangement and size of mineral grains in a rock, whether they are fine-grained, coarse-grained, or other specific characteristics.
Visible crystals or grains would be referred to as a coarse grained texture.
