WebAmphibolite and gneiss are both metamorphic rocks. The main difference between the two is that amphibolite is non-foliated, while gneiss is foliated. Foliated rocks are those that have been formed through the process of metamorphism and have visible layers or bands. Non-foliated rocks do not have visible layers or bands. Is Amphibolite Magnetic?
