Samples for strontium isotopic screened were selected by way of the test of cathodoluminescence , observation of thin sections , and analysis of sr and mn . the mn / sr value of all samples presented in this paper are less than 2 , and the cathodoluminescence is dull , however , the samples from the cambrian underwent diagenetic alteration to a certain degree , and the plotted points of the thickness and 87sr / 86sr value are somewhat discrete . the strontium isotope evolution curve drawn from the data with relatively low 87sr / 86sr value are consistent with other curves based on samples from different areas of the world , supporting the notion of global consistency of strontium isotope composition of marine carbonates
