1 The paleogeography was dominated by the supercontinent of Gondwana to the south, the continent of Siberia to the north, and the early formation of the small supercontinent of Euramerica in between.

2 The Lithofacies paleogeography and the thickness variation of Maokouan Subseries and Wuchiapingian Stage in east part of South China are analyzed and some questions in dispute are discussed.

3 In these lithofacies paleogeography maps, the determination of paleogeographical units is based on quantitative single factor data.

4 Controlled by the normal faults, the lithofacies paleogeography when the Middle Triassic Leikoupo Formation deposited showed differences between eastern and western parts of the researched area.

5 Therefore, the study of the lithofacies paleogeography of Majiagou Age in Ordos has important significance in both geological theory and production.

6 Sedimentary thickness isoline graph,[] litho facies paleogeography graph and paleocurrent rose graph were plotted.

7 Based on the study and correlation of sequences, the stratigraphic framework of the Qingbaikou system of the Yanshan region is set up, and the evolution of paleogeography is discussed.

8 According to the geological characteristics of Liuju copper deposits, the controlling ore-forming factors include stratigraphy, lithology, structure, lithofacies and paleogeography.

9 The Middle Permian Chihsia Formation of South China is featured by nodular chert, which is of implications in the reconstruction of coeval paleogeography and paleoceanography.

10 After initial sediment and consequent concentration, the formation of the phosphorite is related closely to the paleogeography.

11 According to"single factor analysis and comprehensive mapping method", the petrography and lithofacies paleogeography of every formation of Qinglong Group has been studied.

12 The lower sedimentary of Yixian Formation show form basin margin to centre three facies coexistence paleogeography characteristics of planar, linear and relatively quiescence water mass depositions .

13 As only one kind of fossil in Proterozoic, stromatolite is an important material in the paleogeography changing study.

14 Guided by the base level theory, the author tried to analyze the paleogeography of the Middle and Late Carboniferous epoch in North China.

15 The paper describes the sedimentary environment, basin framework and tectonic paleogeography in different regions in the joint of Qinling, Qilian and eastern Kunlun, Northwest China.

16 Studies of the slope carbonate gravity current are of important significance in the studies of paleogeography and paleotectonic environment.
