The unique clastic formation preserved in the Yangtze Craton provides excellent material for studying the mid- Neoproterozoic evolution, and the abundantzircon U- Pb ages of tuff interlayers within also provide effective geochronological constraints for the mid- Neoproterozoic evolution of the Yangtze Craton. However, the evolution of the Liantuo Formation in the Yangtze Craton still lacks geochronological constraints, which restricts study of sedimentary evolution of the Yangtze Craton in the late Tonian. In this study, field geological investigation and LA- ICP- MS technology were used to obtain 763.1±6.2 Ma (Shennongjia) tuff zircon U- Pb concordant age at the bottom boundary of the Liantuo Formation, 761.8±7.1 Ma (Hefeng) tuff zircon U- Pb concordant age in lower part of the Liantuo Formation, 764.1±3.5 Ma (Tongshan), 751.5±6.3 Ma (Changyang), 752.1±6.5 Ma (Shennongjia) of tuff zircon U- Pb concordant ages in marine- terrestrial strata of middle and lower part of the Liantuo Formation, 729.6±9.2 Ma (Xiuning Formation), 722.4±4.5 Ma (Shennongjia) tuff zircon U- Pb concordant ages in marine strata of upper part of Liantuo Formation, and 712.4±6.4 Ma tuff zircon U- Pb concordant age in middle part of the Longtanhe Formation. These data and stratigraphic sequence show that: 820~770 Ma Yangtze Craton was exposed to erosional environment, terrestrial deposit began ~770 Ma, after 750 Ma Yangtze Craton completely transitioned to marine deposit that continued until Cryogenian. The strata framework during the late Tonian shows that the evolution of Yangtze was controlled by Rodinia supercontinent breakup process, and may be closely related to deep mantle plume induced extensional rift, magmatic mantle plume cooling. This study provides effective geochronological constraints for the late Tonian strata in the Yangtze Craton, reveals synergistic relationship between sedimentary evolution and tectonic background of Yangtze Craton during the mid- Neoproterozoic, provides effective data support for evolution of Yangtze Craton during Rodinia breakup.
