Pre-Cenozoic basement structure in the Truong Sa archipelago and sea deep basins
Abstract
The structure of marine Cenozoic basement is a problem that has greatly concerned marine geologists and geophysicists engaged in geological study and oil-gas exploration. In this paper, the author has applied a methodology involving gravity data interpretation including frequency filtering, horizontal gradient and maximum horizontal gradient, to define clearly the structure and form of faults and uplift zones in basement as well as the seafloor spreading axis and crustal boundary in the Truong Sa archipelago and the East Sea deep basins.
These results allow some initial remarks concerning the structure of the Cenozoic basement in the Truong Sa archipelago and the East Sea deep basins to be made.
