This study represents the precursor and complementary study for the new classification of granitic pegmatites by Wise et al. (this issue) and provides a detailed analysis of existing classifications of granitic pegmatites in terms of applied classification criteria and applicability. The analyses revealed that a new classification scheme for granitic pegmatites is required. In the second part measurable, inferred, and presumed classification criteria applicable for the classification of pegmatites are listed and discussed, including how they should be utilized in future classification schemes. This study records the process of how the new classification scheme for pegmatites was developed.
