摘　　要：中国菊花石产于二叠纪栖霞组碳酸盐岩层位中。菊花石经光学显微鉴定、ｘ－射线衍射分析和ｘ－射线能谱仪测试，其原生矿物主要为天青石和菱锶矿，两种含锶矿物后期广泛被方解石、白云石和石英交代。依据其菊花石原生矿物组成，将我国菊花石划分为天青石型（浏阳菊花石为典型）、菱锶矿型（宣恩、来宾菊花石）和天青石－菱锶矿混合型（永丰型菊花石）菊花石三种类型。The chrysanthemum stones in china are located in carbonates of Qixia Formation of lower Permian. Based on the optical spectroscopic identification, x-ray diffraction analysis and x-ray energy spectra aralysis, the main prinary mineral compositions of chrysanthemum stones are celestite or/and strontianite, which are often replaced by calcite、dolomite and quartz in later period. According to the primary composition, the chrysanthemum stones in china are divided into three types:i.e. celestite type; strontianite type and celestite strontianite type.
