Abstract:

The northern Red River basin and adjacent areas are located both in the mainland and sea of Bac Bo gulf. The paper investigates structural units in this region where generally conducted separately due to the lack and heterogeneity of geophysical data or the different purposes in projects between land and marine areas. In this paper, authors have corrected the two gravity field data on land and marine satellite gravity data that are combined with a 3D process to determine the depth to Conrat basement continuously from the mainland to marine. Analysis process methods combined with the spectral energy density, the correlation linear regression method, the forward and reverse 3D method to determine the Conrat depth. The Conrat depth changes from 14,2km to 17,2km. The main structure trends northwest-southeast direction.
