WebIn structural terms, banding is a foliation with a spacing larger than 1 cm, consisting of coarse-grained minerals that we well visible with the naked eye. A rock which is more fine-grained and more pervasively foliated is a schist (representing also a lower grade metamorphic rock, compared to gneiss). WebOct 7, 2024 · Foliated rock is also known as S-tectonite because it is sheared rock massed. A typical metamorphic rock sequence is made up of slate, phyllite, schist, and gneiss. The fossilization process is similar to the original sedimentary process, but it is frequently oriented slightly different.
