Visible crystals or grains would be referred to as a coarse grained texture.
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.
A rock that has interlocking grains with no specific pattern is known as a non-foliated rock. Examples include quartzite and marble. These rocks form from the recrystallization of minerals under high pressure and temperature conditions, resulting in interlocking grains without a preferred orientation.
Gravel, cobbles and boulders are all individual clasts of increasing size that are larger than sand.
Fine grains of rocks are referred to as "clasts." The word "clast" comes from the Greek word "klastos," meaning "broken."
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.
Coarse grain
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.
Visible crystals or grains would be referred to as a coarse grained texture.
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 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.
fine-grained
When all grains in a rock are large and easy to see, the rock is described as coarse-grained.
We call them clastic rock also referred to us the sedimentary rock.
A rock that has interlocking grains with no specific pattern is known as a non-foliated rock. Examples include quartzite and marble. These rocks form from the recrystallization of minerals under high pressure and temperature conditions, resulting in interlocking grains without a preferred orientation.
