Those would be non-foliated metamorphic rocks, like quartzite and marble.
no texture
no texture
mineral grains arranging into layers.
Foliated.
schist
A schistose texture.
Not exactly. Some metamorphic rocks have foliation, which can appear similar to the layers of sedimentary rock. Foliation develops from mineral grains being oriented by pressure, rather than the deposition of layers.
Foliated is the general descriptive term used to describe the layering or banding of metamorphic rock.
Nonfoliated
Lesson 5: Metamorphic RocksScience 7 A Unit 2: Earth's Materials1. All of the following conditions in Earth can cause metamorphic rocks to form except _____. (1 point)(1 pt) exposure to air(0 pts) the presence of hot, watery fluids(0 pts) heat(0 pts) pressure1 /1 point2.Metamorphic rocks that show layers of dark minerals alternating with layers of light minerals are classified as _____. (1 point)(0 pts) nonfoliated(0 pts) detrital(1 pt) foliated(0 pts) intrusive1 /1 point3.Metamorphic rocks with a nonfoliated texture show metamorphic change that involves _____. (1 point)(0 pts) mineral grains arranging into layers(1 pt) growth in the size of the mineral grains(0 pts) mineral grains flattening under pressure(0 pts) mineral grains melting1 /1 point
There are two answers to this question1) gneissicfor bands in such as granitic gneiss2) foliated for thin layers seen in schist.
Metamorphic rocks have their grains arranged in parallel layers or bands that are said to be foliated.
