How does contact metamorphism work
WebContact metamorphism happens when a body of magma intrudes into the upper part of the crust. Heat is important in contact metamorphism, but pressure is not a key factor, so contact metamorphism produces non-foliated metamorphic rocks … WebDec 16, 2014 · 1 Answer Julian M. Dec 16, 2014 Foliation in metamorphic rock is formed by uni- or bi-directional strain, often under high temperature and pressure conditions, that allow laminar deformation along planes of weakness between layers, mineral grains, and molecular bonds.
