| Abstract: | The macrofeatures of rock association and sedimentary structure association of the pre - Sinian Niuwu Formation , DaguyunFormation and Zhentou Formation are described on the basis of the Lantian, Tankou, Jindexian, Qidu, etc. sheets of 1 : 50000 scale regionalsurvey accomplishments and subject study with the Qiashe - Zhaixi profile as an example. A preliminary analysis has been made on thesedimentary facies and sequence strata. And new contents add to the above mentioned lithostratigraphic units. |
