Yes, and they often are, and appear as foliations.
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.
no texture
It is likely a type of metamorphic rock, such as schist or gneiss, which form under high temperature and pressure conditions leading to the alignment of mineral grains into flat layers.

Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
A rock with long flat mineral grains is likely to be schist. Schist is a metamorphic rock characterized by its foliated texture, with mineral grains aligned in a parallel fashion, giving it a distinct layered appearance.
