Gneiss is course grained but it has a fabric.
Gneiss is foliated and coarse grained
coarse grained
Gneiss, pronounced 'nice', is a coarse grained banded metamorphic rock.
Fine grained has larger crystals and coarse grained has smaller crystals
Fine grained has larger crystals and coarse grained has smaller crystals
Gneiss is generally coarse-grained.
shale is fine grained
The list that orders rocks in increasing grain size and increasing grade of metamorphism is: shale (fine-grained) - slate (fine-grained) - phyllite (medium-grained) - schist (medium to coarse-grained) - gneiss (coarse-grained).
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
fine grained or coarse grained
Slate typically does not have abundant coarse-grained mica in it. Mica is more commonly found in other metamorphic rocks such as schist and gneiss. Slate is formed from the low-grade metamorphism of shale or mudstone, resulting in a fine-grained, foliated rock without abundant coarse-grained minerals like mica.
