| Abstract: | An important fact in the analysis of geochemical stratigraphy is that there is the feature of geochemical cycles with imposed different spatial or temporal scales, which were controlled by enviromental factors with different scales. Therefore, recognizing of different scale geochemical cycles by means of some tools is useful for the study of palaceanography. In the present paper, the author puts forward a tool used universally for this purpose in mining geology and in prognosis of mineral resource, variogram. And by making use of oxygen and silicic istopic composition, the efficency of variogram for recognizing of periodicity of geochemical cycles in deep sea sediments is illustrated. |
