In the process of deep geological structure research, gravity and aeromagnetic anomaly data are often used to invert the distribution law of concealed geological bodies. In order to reveal the boundaries of concealed geological bodies and divide structural divisions, this paper adopts fuzzy control simulated annealing genetic algorithm () to superimpose the gravity and aeromagnetic anomaly data in Benxi-Xiuyan area and classify the patterns, and identify the main geological body boundaries and fractures. Comparing the relationship with known geological maps, the two have a higher degree of matching. Experiments show that the application of SAGAFcm algorithm can quickly identify the boundaries of concealed geological bodies and provide a new means for field geological mapping.

The career of Jean-Baptiste-Julien d'Omalius d'Halloy (1783-1875), commencing with brilliant scientific activities and proceeding to his attainment of the highest administrative and political positions, in itself demonstrates that he was an exceptional individual. His scientific career started with a long voyage through the French Empire and adjacent regions, during which he gained an understanding of the geological structure of most of Europe. The geological map he compiled based on his travel notes formed the basis of all future geological maps in the areas that he covered. After the independence of Belgium in 1830, André Dumont was made responsible for the mapping of the whole country, resulting in the publication of a 9-sheet map of Belgium in 1853 on a scale of 1:160.000. In 1878, Belgium decided to produce a more detailed map on the scale of 1:20.000, entrusting the work to Edouard Dupont., but as this appointment was controversial and the mapping at this scale was abandoned and than, the newly created Geological Survey of Belgium published a new 226-sheet map on a scale of 1:40.000. Starting from 1993, after the federalisation of the country, new geological maps of the regional states are mapped and produced.

Cenozoic sediments of the territory of the Brest region is the object of research in this work. The aim of this work is to detail the structure of the Cenozoic stratigraphic deposits by creating a set of structural geological maps. The process of creating maps included several sequential stages implemented using the ArcGIS 10.5 software product. In general, a set of maps for each period of the Cenozoic era was made according to the implemented method. As a result of mapping, the features of the geological structure of the Cenozoic sediments were detailed (based on the use of the most complete materials on the drilling exploration of the territory during the construction). The use of geoinformation systems in the process of building will allow for quick updating of cartographic materials in the future.

A mathematical model was constructed with two objectives. A two-stage hybrid algorithm was developed for solving this problem. At first, the man-hour optimization based on genetic algorithm and dynamic programming method, the model decomposes the flow shop into two layers: sub-layer and patrilineal layer. On the basis of the man-hour optimization,A simulated annealing genetic algorithm was proposed to optimize the sequence of operations. A new selection procedure was proposed and hybrid crossover operators and mutation operators were adopted. A benchmark problem solving result indicates that the proposed algorithm is effective.

The issues of import substitution of geoinformation systems used in the geological industry when creating sets of State geological maps of the scale of 1:1,000,000 and 1:200,000 are considered. The current state of the issue is described. Additional functionality is indicated, which is necessary for the construction and preparation for publication of digital models of the maps of the set. Examples of domestic GIS are given, which can replace the foreign analogues in use. The problems and difficulties arising in this case were revealed. The ways of their solution are suggested.
