The Doushantuo Formation sequence classification of the Eyangye 1 Zidi 1 and Zidi 2 wells show that the Doushantuo Formation consists of three third order sequences Dsq1 Dsq2 and Dsq3 in Fig 2 Fig 3 and Fig 4 respectively and each of the third order sequences consists of a TST and a highstand system tract HST The sequence of Dsq1
The Sichuan Basin is a large marine and continental basin in China with marine carbonate rocks from the Sinian to the Lower Triassic The Sinian strata in the Sichuan Basin can be divided into Doushantuo Formation Z 2 do 700 670 Ma; Wang et al 2006 and Dengying Formation Z 2 dn 670 542 Ma Yang 1994; Mei et al 2006a b The Dengying Formation
Abstract Based on the study of regional geology in Jinning area Yunnan province we suggested that the Jinning movement was an orogenic movement during late period of Middle Proterozoic and it could be compared with the Grenville study of Jinning movement in the Yangtze and Tarim blocks suggested that the both blocks were some kinds of
In the Late Sinian Doushantuo Formation a set of source rocks composed of black shale dark grayish black micritic limestone and carbon bearing mudstone was divided into a second order sequence
A new biota composed of the macrofossils in the upper Sinian deposits at Miaohe is de scribed None of the earlier reports on metazoan fossils from the Doushantuo Formation is compelling In our finding all of the metazoan fossils belongs to worm roughly but the
This study evaluates the pore network systems in the Neoproterozoic Sinian Doushantuo Z 1 d shale from the Yichang area in the Middle Yangtze region All samples were classified based on their lithologies and examined by geochemical and petrographic analysis assisted with carbon dioxide/nitrogen CO 2 /N 2 adsorption mercury injection capillary
The Ediacaran Doushantuo Formation in South China ca 635 541 Ma; [22] after the Marinoan snowball Earth glaciation witnessed fundamental ocean redox changes which was widely recorded in the Rinkabeena and DeyDey Formations of the Centralian Superbasin Australia the Masirah Bay Formation of the Huqf Supergroup South Oman Salt
： In recent years natural gas exploration in the Sinian Dengying Formation and shale gas exploration in Doushantuo Formation have made major breakthroughs in the Sichuan Basin and its adjacent the sedimentary background of the Doushantuo Formation hasn t been studied lithofacies paleogeographic pattern sedimentary

And all of these 4 carbon isotope anomalies are reflections of geologic events the anomaly of the bottom part of Doushantuo Formation is a reflection of "the snowball Earth"in this area; the negative shift of the carbon isotope of the middle part of Doushantuo
Abstract The genus of large sized acanthomorphic acritarchs Tianzhushania was named from Tianzhu Mountain in Changyang County Hubei Province where it was first described and its typical species was first found from chert nodules in thin sections from the Sinian Doushantuo this paper the authors summarize the reports and
It reveals the sedimentary micro facies characters of Weng an biota in Doushantuo Formation from bottom to top the Doushantuo formation experienced three times paleogeographic environment of low tidal flat middle tidal flat up tidal flat which the water power

Finally we propose that large scale distribution of high quality source rocks developed in the interglacial Datangpo and Doushantuo formations while fluvial deltaic reservoirs occurred in the Gucheng Nantuo and Doushantuo formations thus showing favourable resource potential and exploration prospects within the Sichuan Basin
