 Stock is a term that is used for a non-tabular body that is exposed for less than 100 km2, and batholith is used to describe anything exposed for larger than 100 km2.This size classification does not take into account the true size of the body, which is why some ambiguity in the use of pluton came about.A non-tabular body can also be classified based on shape, if the bottom of the body is parallel with the underlying country rock then it is termed a laccolith.
