Intrusive
large grains
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
Granite has large mineral grains compared to obsidian, basalt, and pumice. Granite is an intrusive igneous rock that forms deep within the Earth's crust, allowing for the growth of large mineral crystals due to slow cooling. Obsidian, basalt, and pumice are extrusive igneous rocks that cool quickly at the Earth's surface, resulting in smaller mineral grains or a glassy texture.

Fine grains of rocks are referred to as "clasts." The word "clast" comes from the Greek word "klastos," meaning "broken."
What kind of metamorphic rock has its mineral grains arranged in planes or bands
Detrital sediment consists primarily of mineral grains that were eroded from rocks on land. These mineral grains are transported by wind, water, or ice and eventually settle and accumulate to form detrital sedimentary rocks, such as sandstone or shale.
