| description | Based on the analysis of the geological records of different tectonic units, and combined with plate reconstruction and geodynamic background, the evolution and their geodynamic background of Myanmar petroliferous basin group are discussed in this paper.The study shows that the basement of Myanmar petroliferous basin group is a metamorphic complex developed in the Late Cimmerian period.From Late Cretaceous to Eocene, the Neo-Tethys oceanic crust subducted towards the NNE under the West Burma block.Accretionary wedge developed on the western edge of the West Burma block, and volcanic arcs, fore-arc rift basins, and back-arc rift basins formed in the West Burma block.Since Oligocene, the Neo-Tethys closed down, and then the Indian block and the northern part of the West Burma block collided, and the basins in the northern part of the West Burma block evolved into back-arc foreland basins.The Indian Ocean crust subducted towards the NEE under the central and southern parts of West Burma block, and the accretionary wedge developed on the western edge of the West Burma block gradually uplifted to the Indo-Burma range.The central and southern basins of the West Burma block on the east side of the Indo-Burma range all evolved into back-arc compressional basins, while the Rakhine basin on the west side of the Indo-Burma range evolved into fore-arc basin.The results of this study have certain indicative significance for the prediction and exploration of oil-gas and mineral resources in the Myanmar basin group. |
