On the basis of this analysis,the authors analyze the origin of the complexity of sedimentary basins of China and point out that the special tectonic position,small and less stable continental block,large-scale and active mobile belt and complex plate tectonic framework and tectonic evolutionary history are the root-causes for the complexity of sedimentary basins of China and caused these basins to have their distinguishing characteristics of petroleum occurrence.
1. The deposition-tectonics evolutionary history in the west margin of Ordos basin include 6 stages: crystalline basement formation stage in the Archaean-Terminal Palaeoproterozoic, stable continental-margin deposition stage in Middle-late Proterozoic-Ordovician, starting stage in the Caledonian thrust nappe structure, marine-continental alternation and inland lake basin formation stage in the late Palaeozoic-Triassic, dominant development stage of the thrust nappe structure in the Jurassic-Neogene period and continuously thrusting nappe stage in the Cenozoic period.
On the basis of the regional stratigraphic correlation, rock association characteristics, isotopic age, mutual relation with adjacent intrusive rocks and combining with the comprehensive analysis of the crust evolutional history, it should be early Proterozoic and established as Guanghua Group.
The ice-free areas in circum Antarctica appear with the climate becoming warm and the ice sheet retreating ,which are the ideal sites to study on the environmental evolutional history in Antarctica ,even on the global environmental change.
According to a report by Wetmore in 1934, the earliest fossils of crane in China were excavated from the stratum of the Eocene Epoch in Inner Mongolia and they were named as Eogruidae, there is a very long history of evolution of cranes in Inner Mongolia.
Geobiology, probing the interaction between the life system and the earth system, provides new principles in deciphering the whole dynamic processes related to the organic evolution history from living biomass to organic burial.
Geological structure of the Curonian Spit (of the Baltic Sea) and its evolution history (revised)
The origin and evolution history of the Curonian Spit in the Baltic Sea are discussed based on geological and geomorphologic data.
Maturity, evolution history, and distribution of effective source rocks controlled hydrocarbon richness.
This article examines Codes in terms of their evolution (history), expectations (from possible to impossible), and enforcement (the area of greatest difficulty).
Widespread geographical distribution as well as a long history of evolution mean that they possess a relatively adaptive anatomy.
Gaia, god, and the internet: The history of evolution and the Utopia of community in media society
Some argue that plant communities on these high-elevation summits reflect a long history of evolution in isolation, while others surmise that there has been substantial biotic interchange with the surrounding lowlands during glacial times.
Mammals, including man, can be regarded as diploid species with a polyploid history of evolution.
The time history of evolution of the temperature at the plate centroid and through-the-thickness distribution of the temperature computed with the fifth-order plate theory are found to agree very well with those obtained analytically.
