摘要	The Lopingian is one of the fastest rising periods of seawater strontium isotopic ratios (~(87)Sr/~(86)Sr) in earth history, and its mechanisms and increasing rates of the ~(87)Sr/~(86)Sr evolution were still disputed widely. These disputations among researchers were caused mainly by timeframe selection (sections’ thickness or data of radiometric ages), and different stratigraphic boundaries and un-upmost dated ages. This paper examined published ~(87)Sr/~(86)Sr data of the Lopingian, and projected them on timescales based on evolutionary and age constrained conodonts fossils. ~(87)Sr/~(86)Sr evolution vs fossil constraining timescales was re-established in this period. This research suggests:(1) ~(87)Sr/~(86)Sr excursion projects on fossil zones can truly support ~(87)Sr/~(86)Sr evolutionary pattern in the period; (2) ~(87)Sr/~(86)Sr evolution provides a new approach for stratigraphic research of marine carbonate sections in lieu of biostratigraphic data; (3) ~(87)Sr/~(86)Sr stratigraphy works on marine carbonate sections of different sedimentation rates even between different basins; (4) the ~(87)Sr/~(86)Sr data and its shift was dependent on samples materials and chemical treatment methods; (5) the increasing rate of marine water ~(87)Sr/~(86)Sr in the Late Permian is suggested as 5.4×10~(-5)/Ma or slightly lower; (6) sedimentation age and its ~(87)Sr/~(86)Sr of the Lopingian marine carbonate suggested as:D_(Pro)=259-(RS- 0.70695)/5.4×10~(-5) (Ma).
