The sigma sign (Σ, which resembles a sideways M) represents the sum of. Sometimes there are numbers above and below the sigma sign. For example, below the sigma sign can be written x=2, and above the sigma sign can be written 6. This signifies the sum of the numbers between the number below, and the number above.

How is deformation related to metamorphic rock structures?

deformation is related to metamorphic rock structures because deformation can create metamorphic rocks through the stress it creates, and also certain structures in the foliations of metamorphic rocks can indicate stress and stress direction from deformation. Some structures caused by stress are folds and faults, and the resulting indicators in metamorphic rocks include things such as sigma structures, Z structures, mica fish, boudinage structures and many others.
