Abstract
The descriptions of various methods of geological interpretation of gravity and magnetic supervision are stated at the decision of geological mapping tasks in absence of the seismic data and drilling. The put difficult geological tasks in practically not investigated by geophysics remote area are described. The geological results of researches are stated. Thus, the carried out transformations of abnormal fields have allowed to answer a number of the put questions. At the same time, the significant part of these questions can not be covered extremely by means of transformations. In view of absence of the standards (first of all, data of drilling and seismic data unique effective method of interpretation was the reception of gravitational modeling. The modeling was carried out on six structures. Earth crust was elucidated up to depths in 10km, according to the above described results of upward continuation.
