英文摘要	From geology and geochemistry studies on four typical large-superlarge nonmetal deposits in eastern Zhejiang Province, it is concluded that nonmetal mineralization is an in situ reduction process in which SiO2 and Fe2O3 are lost, and Al2O3 and K2O are enriched. Moreover, incompatible elements are depleted in zeolite but enriched in alunite. Rb-Sr isotopic age of zeolite and K-Ar isotopic age or micro-area Ar-40-Ar-39 isochron age of alunite are coincident with their geological data, respectively. Comparison studies of various chronology methods indicate that K-Ar and Rb-Sr methods are effective for zeolite and alunite, but should be carefully used for pyrophyllite, dekite and illite. From isotopic ages of ore and wall rocks of zeolite and alunite, it could be deduced that the age difference of metallogenism and volcanism is about 10-20 Ma.
