Abstract: Resent years, high-frequence cycle charged by Milankovitch cycle as an importantmanner for stratigraphic classification, conforming age, and discussing basin evolution, is tried to used to continental rift-subsidence basin.But continental rift-subsidence basin is structure basin, fault structure theory, a lot of sedimentation and structure phenomenon which are on or under the surface show us that there is probably influence which short-period ep isodic rifting control the sedimentation of high-frequence cycle. The influence is need to eliminate before using Milankovitch cycle in continental rift-subsidence basin. In recent period, the primary research maybe be limited some sides. The first is to find out sedimentary response of short-period ep isodic settlementwithin deposit of high-frequence cycle; the second is to research sedimentary feature, lateral change and contrast of tectonic high-frequence cycle with different sedimentary location and source distance; the third is to study accurate index and contrast of paleoclimate and paleo- water depth in lacustrine high-frequence cycle. These sides are very important before to pick-up Milankovitch sedimentary cycle accurately.
