The recognition of this kind of strontianiferous aragonite is important in the study of isomorphism and inner structure of aragonite. Its discovery and study are of great significance in the application and exploitation of the mineral. By such means as infrared spectrometer, Raman spectrometer, visible spectrophotometer and SEM, this paper has analyzed characteristics of the spectra, texture, color-causing mechanism, distribution of Sr2+, Ca2+ ,Cu2+ and layering of the mineral. The infrared absorption and Raman frequency of v1, v2, v3, v4 of CO2-3 are found just between aragonite and strontianite, which is attributed to substitution. Meanwhile, there is a splitting peak v4 of CO2-3 in the infrared spectra. EMPA reveals that CuO content is 0.00%～0.39% in blue strontianiferous aragonitebut very rare in white strontianiferous aragonite. It is found that the color mechanism of blue strontianiferous aragonite has something to do with Cu2+ .Surface scanning shows that Sr2+ and Ca2+are distributed along the zonal texture while Cu2+ is in random distribution. In addition，SEM shows that strontianiferous aragonite displays different microstructures and morphologic features. The changes in microelement contents, temperature and pressure cause the formation of different color zonal textures.
