Abstract

In this article, the authors present an application of new techniques for processing and interpretation of gravity data to determine the structures of the Pre-cenozoic I basement such as: 3D inverse problem to determine density distribution, the analytic I signal of gravity gradient tensor method, the Euler deconvolution of the directional analytic signals, and the curvature tensor gravity gradient. Each method was tested on I model and applied on the real data, and the advantageous as well as disadvantageous I aspects were found out from the results. The combination of these results from all the I methods is allowed US to better understand structures of the Pre-cenozoic basement. In I fact, some structural elements and rock density distributions inside the Precenozoic I basement of the Red River sedimentary basin and its surroundings are more clearly 1 refelected on our results in comparison with the previous studies.
