HUANG Si-jing, SHI He, LIU Jie, SHEN Li-cheng. PROGRESS IN STRONTIUM ISOTOPE STRATIGRAPHY[J]. Advances in Earth Science, 2001, 16(2): 194-200.

Strontium isotope stratigraphy relies on the fundamental principle that the marine strontium is isotopically homogenous world wide at any time and the 87Sr/ 86Sr ratio of strontium in seawater of geological history has varied through time. By means of the 87Sr/ 86Sr ratio of marine carbonate (also phosphate and sulphate) which should record the original composition of sea water, we can date the marine sediments, research global events, such as history of basin subside, sea level change,orogenic events and palaeoclimate variation. The applied expectation of strontium isotope stratigraphy would be very extensive on stratigraphy, sedimentology, petroleum geology and economic geology, which has attained considerable development internationally. However strontium isotope stratigraphy is still in its infancy in China. The focus of strontium isotope stratigraphy is the influence of diagenesis and technology of measurement of 87Sr / 86Sr ratio. Meantime, strontium isotope stratigraphy also needs the support of stratigraphy. The ability of anti alteration of diagenesis of the original component of sample for strontium isotope stratigraphy is very important. The development of strontium isotope stratigraphy needs a great effort from stratigraphers, sedimentologists and geochemists, together.
