Using balanced cross-section and backstripping techniques, we reconstructed the stratigraphic deposition and tectonic evolution histories of the basin. The basin formed from the Eocene and was generally in an extensional/transtensional state except for the Late Miocene local compressoin. The major basin extension ocurred in the Oligocene and Early Miocene （before -16.3 Ma） and thereafter uniform stretch in a smaller rate. The northern and middle basin extended intensely earlier during 38.6-23.3 Ma, while the southern basin was mainly stretched during 23.3-16.3 Ma. The basin formation and development are related to alternating sinistral to dextral strike-slip motions along the Wanan Fault Zone. The dominant dynamics may be caused by the seafloor spreading of the South China Sea and the its peripheral plate interaction. The basin tectonic evolution is divided into five phases： initial rifting, main rifting, rift-drift transition, structural inversion, and thermal subsidence.展开更多

In the context of beautiful countryside,it is necessary to maintain development advantages,transform development disadvantages,strengthen rural infrastructure construction,attract investment,vigorously introduce professional talents,explore more industrial models with the support of the government,and promote the stable and healthy development of characteristic industries.展开更多
