2. Exoskarns occur at and outside the granite which produced them, and are alterations of wall rocks.
3. Here, fluids react less via chemical exchange of ions, but because of the redox-oxidation potential of the wall rocks.
4. However, the widest use of the word is in describing the metasomatised zones of wall rock adjacent to granites.
5. Gravity surveying can be used to detect dense bodies of rocks within host formations of less dense wall rocks.
6. In volcanoes, wall rock can often become broken off the wall and incorporated into the erupted volcanic rock as xenoliths.
