Based on the latest 1∶250 000 gravity data of Delingha area and combined with the relevant known data, the authors carried out the new extraction and inversion interpretation of gravity anomaly. The study shows that the current gravity anomaly characteristics in Delingha area can reflect the basement structure. In this paper, 14 regional fault structures were interpreted by wavelet fault analysis method, and the basement structure of "five depressions and three uplifts" in Delingha area was recognized by the density interface inversion calculation of Parker method. The uplift and depression pattern of the current regional basement in Delingha area was defined, the undulating change and depth of the uplift and depression of the basement were inferred, and the attribution and supplement of some previous achievements were made. The authors hope that the result of this study will play a guiding role in the deep structural analysis, mineralization research and oil and gas resource prediction in Delingha area, especially in the Chaidong basin.
