The alteration zone and its sequence of greisen, composed of muscovite, quartz, topaz, elbaite and fluorite, can be expessed by the(OH, F)-Si-A1 com- position-paragenesis diagram. According to the difference of combination of these five paragenetic minerals (paragenetic phases) in greisen, five alteration types can be recognized, which can be differentiated each other by their own characteristic paragenetic mineral assemblage and sequence of alteration zone. The boundaries between the adjacent types are examined by the change of the arrangement of tie lines between coesisting phases (a kind of univari- ant reactions).These five alteration types constitute a petrogenetic grid, char- acterized by 2, 2, 1 pencil of says. Each alteration type corresponds to a diva- riant field. Further more, twa evolving series of alteration type can be set up, according to the reduced order of chemical potential of O2.
