  BOX 5B RELATIONS TO OTHER MINERAL SPECIES (IMA)
RELATIONSHIP TO OTHER SPECIES
Pezzottaite is related to the beryl group (see table 2), but differs in having a superstructure involving ordering of Be and Li in tetrahedral coordination (see Fig. P1, P2 and P6).

BOX 6 MISCELLANEOUS (IMA)
NAME
----------------------------------------------------------------------------------------------------------------------------------------------------------------
Named after Federico Pezzotta, Museo Civico, Milano, Italy; born 1967. Dr. Pezzotta has played a major role in characterizing the granitic pegmatites of Madagascar and their constituent minerals. He has made major contributions to our knowledge of the paragenesis of tourmaline-group minerals, particularly in Elba, Italy.
