The wide range and quantifiable covariation of the concentration and isotopic composition of strontium may be the parameters of precipitation rate, media environment, crystal growth mechanism and biological effects. With the advancing analysis technique and the improving theoretical modeling of Sr concentration and isotopic variation, the study on the trace element and isotope geochemistry of Sr become increasingly important tools for understanding the hydrological cycle and carbonate diagenesis, and for evaluating the paleoenvironment and modern environmental problems. This paper reviews the study on strontium' s trace element and isotope geochemistry and offers new perspectives into their applications.
