This article is devoted to new technologies which are makes the solution of the gravity inverse problem less time-consuming. Gravity inverse problems are considered in the structural definition and so may be both linear and nonlinear. The key to increase of the productivity of new technologies consist in use of binary trees representing the hierarchical ordered structure. The application of these structures allows making the decomposition of the intricate computational problem on series problems which have lesser dimensionality. Moreover, we present a new algorithm based on the finite element approach and oriented on the solution of the gravity inverse problem in the linear structural definition.
