Web28 Aug 2011 · The heterogeneous nature of the rock results from partial melting (called anatexis) that occurs when a precursor rock is exposed to high pressures and temperatures. The light-colored layers originate from the partial melting and have igneous characteristics– that is, their appearance indicates that they have been crystallized from a melt. WebIgneous Rocks are formed by crystallization from a liquid, or magma. They include two types. Volcanic or extrusive igneous rocks form when the magma cools and crystallizes on the surface of the Earth. Intrusive or plutonic igneous rocks wherein the magma crystallizes at depth in the Earth.
