| Abstract: | The Jurassic section in Dameigou, Chaidamu Basin is analyzed by high resolution sequence stratigraphy and the relationship between coal accumulation and high resolution sequence is also discussed. On the basis of the analysis of facies type, facies association and facies series, the Jurassic section is divided into 7 middle term cycles and 10~12 short term cycles by using the theory and method of high resolution sequence stratigraphy. High resolution sequence stratigraphy, which is based on the control of baselevel rising and falling, can improve the precision of stratigraphic division, and it is an effective way to research continental sequence stratigraphy and predict correlation of reservoirs. |
