In the course of the work, structural maps were constructed and analyzed on the surfaces of the horizons of the lower and middle carboniferous, as well as maps of the isopachite local uplift of one of the deposits of Tatarstan. Three separate domes, northern, central and eastern, have been installed on the studied uplift of the deposit. To determine the sequence of development of a number of surfaces, when constructing paleostructural maps, the authors used the “isopachic triangle” method, according to the constructed maps, the authors received information about the movements, structural forms and the relationship of these forms at different stages of geological history.

Materials and methods
According to logging diagrams and conclusions of well interpretation, the values of the absolute roof marks of the vereyan, bashkirian, tulian, bobrikovian, tournaian and upino-malevian sediments were removed. Structural maps, as well as isopachite maps between the deposits of the middle and lower carboniferous, were constructed from the removed chops. By using the “isopachic triangle” method, the sequence of the development of the roof surfaces of horizons on the constructed structural maps and isopachite maps is determined.
